Some words.
My cheap tweaked and second hand AV Marantz SR4500 (class AB) sounds better after a warm-up too. I use white, pink and brown noise from computer, with low volume -> high volume in the amplifier. I use a soft player only to them, 1by1, with low volume fixed. JRiver and foobar2000 to play music.
And to warm-up the rigid suspension of my coaxial speakers, KEF Q100. News, without very long burning, they lack of bass. That is why many compulsive buyers returned them and had little success during their early years.

News, with a subwoofer is all OK off course.
After the long burning: classical, baroque, jazz, folk... without a subwoofer the sound is very good. I do not need a sub in my room. You can up the bass with a good soft equalizer if you listen modern music with too bass.
In a big room, I would try with two subwoofers at 130 Hz or more. With one sub, f > 65 Hz. Why? Because 65 Hz is the woofer fs - resonance frequency - (and the 130 Hz the second harmonic). With the front bass-reflex plugged with the sponge.

Update 01/26/2013:
I’ve been using these Kef Q100 speakers (driver and cabs) as my reference/experimenting setup with dolby, L7, etc recently and I can say unequivocally, these are by far the best set of speakers I’ve heard in their respective size range. The imaging and soundstage along with vocal acuity is incredible. When I first fired them up I was extremely impressed. Walking around the speakers, there is no dramatic drop in response; the sound power response is excellent.
I had every intention on selling these to get funds back but at this point I’m making every effort to not have to sell them. I’d like to make them my new reference setup.
A sub to pick up below 50hz mated to these would make a very potent and worthwhile setup rivaling many tower based setups I’ve heard. And this is coming from the guy with a set of Zaph ZRT 2.5’s. the cool part is its extremely portable so I can take it to meets and demo for others.
Kef really nailed this speaker. For its price I have yet to find anything I think could beat it.

Z Review - KEF LS50 [SOUND DEMO]
https://www.youtube.com/watch?v=FVPSlrWYvdY
Amazing again.
The expensive KEF LS50 has rear bass-reflex. Somewhere I read that they need at least 90 cm / 35" away from the back wall and the side walls to sound properly.
KEF Q100, with front bass-reflex is less problematic.

By Mr. CPRon January 15, 2018
Nice looking speakers, but I wish I would have listened to them in person locally prior to buying them on Amazon. I'm new to Prime and thought everything had free returns and I was going to be able to listen to them risk-free, but now I'm out the cost of return shipping. Oh well. About the speakers, though, I thought they were a bit unnatural-sounding with voices and bass. I used to run sound boards for concerts, events, and have done some recordings and there are some musicians whose voices I'm intimately familiar with. These speakers have a more "tinny" sound to the voices that my other home speakers don't have. When listening to an upright bass, kick drum, or any other bass-producing instruments, you really need a subwoofer to fill in what's missing. I wouldn't count on these KEF Q100s to produce anything below 100 Hz accurately. I know picking out speakers is highly personal and these are only my opinions, but I hope it helps emphasize the importance of going to listen to speakers in person first before ordering online, even if the reviews for those speakers are glowing.
Again, KEF Q100 needs a long burning. And power too. With 80 watts at 8 ohms or more like my cheap tweaked and second hand AV Marantz SR4500.
Somewhere over the rainbow I wrote:
I bought Boston Acoustics A25 to a familiar (new and € 135, I won a bid -eBay- from a UK shop). It does not need burning. I had just bought the KEF Q100 (€ 399), and the Bostons sounded better because they had more bass. But after a long burning the first are much better and with more bass.
Trust me, KEF Q100 is the best option. I LOVE them after my cheap tweaks. 5.25″ KEF coaxial speakers are magics. But you need power. Better 80 watts or more at 8 Ohms.
The Boston Acoustics A25 and second hand AV Marantz SR7500. Very good amplifier. I bought first my second hand AV Marantz SR4500.
They have rear bass-reflex. ELAC and Wharfedale too. (*)
KEF Q100 or Focal Alpha 50. Or you need to spend much more money.

Its too bad the LS50s
By Jason Diddayon February 22, 2018
I decided to upgrade my Peachtree D5s to something new and considered these KEF Q100s and the Elac UB5s. The KEFs won out hands down. Considering the praise received on the UB5s and the fact that they are almost twice the price, I'd have expected a tougher decision. It is important to point out that I am running these on a Peachtree 220se amp so I have plenty of power. I am listening to these in a super-near-field setup where I sit practically 3 feet away. And they are placed into my office bookshelf against the wall - so the front porting is a major positive. Its too bad the LS50s, the Q150s and 350s (and UB5s) are all rear-ported.
These KEF Q100s are crystal clear, extremely accurate and quick, with a deep bass (when called for). Ive listed to Notorious BIG, Live After Death where I get nice bass and Toto's 40 Trips Around the Sun where you get great vocals and musicality. Absolutely love these for $300...its really hard to believe they cost so little. If you need rear porting, pick up a pair before they're discontinued.

Talking about KEF K350...
KEF Q350 loudspeaker Measurements
https://www.stereophile.com/content/kef-q350-loudspeaker-measurements
My estimate of the KEF’s sensitivity was 86.6dB(B)/2.83V/m, which is within experimental error of the specified 87dB. Though the impedance magnitude (fig.1, solid trace) drops just below 4 ohms at 180Hz and there is a combination of 5 ohms and a –39° electrical phase angle at 125Hz, the speaker is a relatively easy load for the partnering amplifier…

Best $250 i've spent on audio thusfar
By James Sasseron April 5, 2018
Do yourself a favor and buy these before they're gone! KEF's already campaigning the replacement Q150's @ $549. Say what you will about "burn-in" time. . . these deliver a very pleasant sound that's slightly more focused (tighter with more coherent bass) than B&W CM1. While I love the lush sound of the CM1's, the KEF Q100's lower treble and mids create an engaging experience during the very 1st hour. No complaints whatsoever.
These are in a medium sized living room approx 15x25, and they fill it up without a challenge. Used with an Emotiva A100 @ 50WPC. Very VERY satisfied.
-
Finally, the last tweak. I have added mass to the speakers => Sound more defined, detailed, separation of instruments... Loss of bass = bass less rumbling. The boxes disappear a little more.

PD: the true sensitivity is between 84 dB and 85 dB I suspect.

The sound of one person posting...

I am not an audiophile and I did a bit of research and was undecided between the Q100 and LS50 and eventually bought both. I agree with the hype around the Q100 since I have directly compared with the LS50 with the same setup (NuPrime amps in a large room). My unscientific observations:
- Q100 is a bit brighter than the LS50
- the LS50's bass is a bit tighter
- Q100 can be driven very easily with 30-50W amps, the LS50 loves current!
- LS50 looks way more cool
- Q100 is front ported hence it can be placed on a bookshelf or on a computer table
The Q100 is not as good as the LS50 but they better not be! Its 80% of the LS50 at 1/4th the cost (I bought the LS50 for 999). For now the beautiful white LS50 is in my living room while the Q100 is in my garage, on a table against the wall (thx for the front ports). If money is not a huge deal, I would always recommend the LS50s!
I am done with speaker purchases for a while. Thanks to KEF!
-
With my cheap tweaks the KEF Q100 sounds much better than original, much better.
Bit brighter -> With a good soft equalizer you can soften the trebble (with Q=0.7 is the best). Or more easy, turn the speakers a little to the walls.
KEF LS50 needs more separation from all the walls, not just from the back. 79 Hz at -3dB -> you need a subwoofer.
KEF LS50 has true 83 dB and the minimum impedance is almost 3 Ohms -> it needs more power to sound OK.
Both sound better on supports.
KEF LS50: 7.2Kg (15.8lbs)
KEF Q100: 5.9Kg (13.0lbs). You can add mass to the case.

iZotope RX 6 Hum Removal VSTplugin
https://www.izotope.com/en/products/repair-and-edit/rx/features/de-hum.html
The De-hum audio plug-in and module in iZotope RX automatically identifies the base frequency of unwanted hum and precisely removes it from the recording along with harmonics -ensuring a clean overall sound without electrical interference.
For more complex hum and buzz removal, the module also automatically recommends when to use De-noise instead, so you'll always have the best tool at hand for the job. The Adaptive mode removes hum that changes in frequency over time.
I like more the sound with Suggest.

[KEF] LS50 vs Q150 audition

...The cabinet is the biggest difference, the LS50 is like knocking on marble, these are your typical cheapish cabinets with a vinyl finish but they aren't bad by any means, just not at the level of the LS50. The Q150 actually digs deeper which isn't too surprising since I believe it has the bigger cabinet.
When the KEF Q100 is out the KEF Q150 promises. The same cheap tweaks that Q100. Considering that it need more space behind because of the rear bass-reflex.

No. This summer I want to build a furniture to my second system. Maybe I can add a new case outside the original or only the two sides -> more rigid like "marble".

They tried it years ago, when they could freely buy the coaxial as spare parts. KEF reacted and since then it asks to demonstrate that the cases were bought.
Each coaxial about $120 !!!

Went from 1 to 5 stars
By bentnailon April 28, 2018
I had prepared a very long review of the the KEF Q100's, an extremely critical one in fact with all kinds of audiophile gibberish. I just deleted that review because something has happened to my speakers. I've never been a big believer of breaking in components, but the transformation in sound from breaking in the suspension on theses UNI-Q drivers...well, this a first for me in 20 years of wasting money in this hobby...a whole different speaker I'm listening to now!
KEF should just put a giant sticker on the box that reads "these are going to sound like ass for the next few days". I was this close to sending the Q100's back because of the thin metallic sound and face melting shrillness.
Reviews got this one right! Break them in HEAVILY, feed them a quality signal, and pair them with a sealed subwoofer...quite addicting now!

Again, these speakers are very good and more at this price. Soon what is left for sale will be over!

Amazing speakers
by Anon9998 on May 11, 2018
These sound incredible! Now that they are broken in, they have extended bass you would not expect from a speaker this size. They also have a very accurate sound with minimal coloration. Sometimes I have to check to see if I left our 12" subwoofer on! We have never owned KEF but have always wanted to. We were concerned about the tweeters being metal because usually metal tweeters have a harsh S sound. We cannot tell these are metal tweeters.
We also own a pair of the Fluance SX6 which we also really like. The Fluance sound amazing but they do not have the accuracy of the KEF's.
We mostly watch movies and use these in our 2.1 setup. We also listen to Josh Groban, Andrea Bocelli, Lindsey Stirling, and other material that requires an accurate speaker like the KEF Q100. These speakers are worth every penny.

Maty, why the polystyrene bypass? Why not just replace the crappy Bennic cap completely? And replace the resistor with a good wirewound like Mills/Mundorf, etc. In fact since there are so few parts it wouldn't cost much to just replace all of them. With such a poor crossover you are going to want all those parts to be as high quality as possible. Replace that cap with a ClarityCap and you won't need to equalize. Same with the resistor. Replace that resistor.
The ferrite on the coil is interesting. Never seen that before. My guess? Inductor gauges that small (20awg probably) carry higher frequencies than thicker gauges. Since that inductor crosses over high and shallow that means its letting too much of the upper mids and higher through. And with a crappy quality inductor that means harsh highs and mids, maybe even over saturated. So the ferrite works because its removing those higher frequencies from the coil. A better solution may just be to get a good 16awg inductor instead. Or replace the coil with a good quality 20awg one.
-
It was trial and error. One day looking at another thing on eBay I found a French NOS caps seller and offered them very cheaply, so I could not resist doing the test. I was just about to buy Jantzen red, recommended by Tony Gee (very gentle person). I liked so much the improvement in the treble so much that I decided that is how it stayed.
http://www.humblehomemadehifi.com/Cap.html
My idea was to change the resistor too with an expensive Mundorf. Tony says me do not change the coil.
I also wanted to change the internal wiring for another one from Neotech SOCT-16 hookup wire (recommended by Danny Ritchie, very gentle person too) but I was unable to dismantle the speakers because the external rings must be very glued!

Würth 150kHz RF ferrite.
It was trial and error too. I have a lot of in my house, and Schaffner RF/EMI FN9244B inlet filters too.
If you put the RF ferrite in the speaker cable (outside the box) -> sound equalized like "U" -> too much highs :(
The same effect, U, with my big 3-way speakers (woofer: 10.8") of the big room, kidnapped by TV and family.
I do not have a logical explanation. I asked in the diyaudio.com forums and silence. As some of you already know, I am very inquisitive. Of course, first I try to find the answer for myself before bothering others.
Trust me, with my cheap tweaks and now with more mass these speakers sound very good, amazing. That is why I insist again and again on recommending them before they run out. They are a safe bet. Both for music and as auxiliary speakers in cinema system (the front bass-reflex is very interesting).

I'm confused. You say trial and error, but it sounds like you didn't actually try the Jantzen or change the wire or inductor, correct? You put on the polystyrene and that was it, right?
I'm going to agree with Tony Gee. A Jantzen 'Red' if you want to crisp clear highs and dimensionality. Claritycap if you want smooth, relaxed highs. Etc. IMO using the polystyrene is putting lipstick on a pig. That Bennic cap is terrible. I used to use them. Get a claritycap and use the polystyrene with that instead. Change the resistor. Those resistors add grain and harshness. You can replace the coil, just measure the value with any multimeter and buy the equivalent in good copper or even foil 20awg. IMO you can get much better sound quality from that speaker with just a little more effort.
-
I did not buy nothing more, only the styroflex aka polystyrene film caps.
And after I optimized the W10 Pro for multimedia, and the soft players. Sometimes I forget a step and immediately notice the difference. Even with movies or series!
As long as the voltage does not exceed 238 Vac I have a great sound especially at night and wekends when my horrible mains is more clean.

They don't have an answer because it's not clear what problem you are trying to fix. And without measurements there's no way to know what's happening. Which is why you'd be better off just starting by replacing with good quality parts first and then proceed from there. Ferrites are undpredictable when is placed in proximity to other components. If the ferrite sounds different INSIDE the speaker as opposed to OUTSIDE (I think that is what you are saying) that means it is affecting the other components. Maybe even the woofer magnets inside.
-
I did not buy nothing more, only the styroflex aka polystyrene film caps.
Replace that cap. Replace the resistor. Don't need anything fancy either. ANYTHING will be better than what is there now (look at Tony Gee's rating for cheap Bennics. Some of the worst ratings in his list). After that remove the ferrite and compare. That would be my suggestion.

Hey Maty, if you are building stuff, get those plans from Decware and build a pair of DNA Horns. My buddy Rex did for about $300 plus his labor and those easily was better than his KEF LS50's. The plans cost him $20 at the Decware site. You can then use your KEF's for your second system.
-
They are yet my second system, where I can listen my musics, you know: classical, baroque, jazz, acoustic, traditional, world music...
In the future only I will want a very good coaxial speakers or tweeter with logarithmic waveguide. The sound is different in front traditional speakers, coherent/time aligned and big soundstage too. Great dispersion.

* Up: frequency response with incredible good dispersion.
* Down: phase response almost flat < 7 kHz
And crossover without any resistors!

If you go fullrange with no crossovers, you will never go back. Vocals are the very best with no crossovers. :thumb:

But with orchestral music is bad choice. And you need a subwoofer too. I listen to few sung music.

Replace that cap. Replace the resistor. Don't need anything fancy either. ANYTHING will be better than what is there now (look at Tony Gee's rating for cheap Bennics. Some of the worst ratings in his list). After that remove the ferrite and compare. That would be my suggestion.

The Best or Nothing
By Coachman30555 on May 20, 2018
These sound so good you think you have an extra pair of floor standing speakers in the room. They make you think twice about adding atmos speakers. I decided on these instead to give the room deeper sound and I'm glad I did. Paired with a Yamaha CX-A5100 & MX-A5000. I could swear I had birds in my living room while watching a golf tournament on tv the other day. Things you don't hear from basic speakers.

Not my cup of tea
By aczn on May 22, 2018
Not my cup of tea. Listened without a sub-woofer using SMSL SA-98E for power. A lot of details in the sound, but the sound was harsh and ear piercing to the point of being uncomfortable. Bass was present but lacking. Developed ear fatigue in about an hour of listening. Was directly comparing them to ELAC B5. B-5 sounded smoother, fuller, and, dare I say, warmer, and I could listen and enjoy them for hours...
How many times have I commented on the need to burn in these speakers? That new sound very bad, without bass, that make you want to return them!
Now is very easy to use the search engines and inform us well before spending money. If not -> compulsive buyer.

160 watt + 160 watt dual BTL class D audio amplifier
More aproppiate to 4 Ohms nominal speakers and not with 8 Ohms nominal like KEF Q100 (4.7 Ohm min).
4. Characterization curves, page 11
Power, in SS, we must look at 0.1% THD always. (Tubes, at 1% THD). The best you can see is at 1% THD because the manufacter hide the curve at 0.1% THD -> much less power. And at 8 Ohms -> even less. KEF Q100 speakers love watts.
Figure 7. FFT performance :( :( .... like the cheap/old class D amps -> a lot of noise at HF -> very bad idea with tweeter, only with subs or woofer.
Very probably the frequency graph at 8 Ohms has a great peak at HF, like other cheap/old class D amps.
But you know, many audiophiles think that specs/measures are not important. They are a necessary condition but not enough. But necessary.
-
To finish, why to hide power at 0.1% THD?
Because this chip is to work with bass frequencies. At low frequencies, the human ear is much less sensitive to the noise -> power graphs at 1% - 10% THD are logical in the PDF.
The problem are the chinese manufacturer and diyers that use an amplifier for another frequency range for which it was not designed. And buyers who do not inform themselves before buying, looking for information or asking in the audio/electronic forums.
Btw, talking about the human ear. It less sensitive with phase shift at LF -> a good active subwoofer you can modify the phase up to 180 - 200 Hz to integrate better with the speakers.
< 180/200 Hz, modifying the phase will not alter the sound quality.

Yup, just get them
By zKi Compon May 27, 2018
There can't be a better speaker set for $250 out there right now. I set these up in sub-optimal conditions and A/B'd them real quick with my recently purchased R500's. Neither are fully broken in, but the Q100 was fresh out of the box.
The R500's sounded better, of course, but the small margin by which they differed was startling. They have similar midrange and soundstage. Q has smaller but tighter bass, as to be expected, but it was still way more bass than this little driver should produce. It really is interesting to put your ear up to one driver and hear nearly the whole spectrum. The R has more clarity and sparkle.
I bought these as side surrounds and now I want to buy another set for my office as a stereo set. At this price, it's super tempting, especially because they won't last forever.

For a small footprint these speakers KICK ASS!
By Allen Woodon May 29, 2018
Wow! After these speakers are broken in the sound is phenomenal! In my small living room which is @ 12X12 with my Adcom GTP 500 preamp and GFA 535 60W per channel amp these speakers offer outstanding imaging and DEEEP Bass. I don't understand how other reviewers can say these speakers don't exhibit good bass. In my environment they do an outstanding job with excellent clarity across the full frequency range.
Don't expect stellar performance right out of the box, but after a good 30 hour or so burn in these speakers really start to open up.
One thing to mention is that these speakers will not do well with sub standard amplification. They will show you very quickly when you have a crappy source. They are brutally honest. Fit and finish is outstanding! These speakers look good in just about any environment, and the sound they produce proves it.
https://www.hifiengine.com/manual_library/adcom/gtp-500.shtml
https://www.stereophile.com/content/adcom-gfa-535-power-amplifier-specifications
Description: Two-channel, solid-state amplifier. Output power: 60W into 8 ohms (17.8dBW). Input sensitivity: 970mV RMS. Input impedance: 100k ohms. Frequency response: 10Hz–20kHz, –0.25dB. S/N ratio: 110dB. Power consumption: 300W.

Note: poweramp with input impedance > 50 kOhms works well with a passive preamp.

As far as the bookshelves, I thought the R300 was better sounding than the LS50 that gets all the press. But I liked the Ascend Sierra and the Klipsch 160 better overall.
-
KEF LS50 passive have a lot of problems:
* At -3dB: 79 Hz -> they need a subwoofer yes or yes.
* Rear bass-reflex. Over there I read that these speakers need at least 90 cm of separation to all the walls.
* True sensitivity is only 83 dB -> you need a powerful amplifier.
* Minimum impedance is 3.3 ohms. Really they are 4 Ohms nominal and not 8 Ohms. More watts.
* High price but cheap components in the crossover, like Q and R series. Very widespread practice in the sector.

As is they sounded better than the others I heard, like Elac and Wharfedale. I'm sure the new xovers sound even better. The Ascends I heard had the ribbon tweeter. Very nice, maybe too much for fans of a laid back sound.

Hi folks,
This topic has been fun, but it has strayed far beyond the scope of this the Sweet Deals Circle. It really belongs in one of the more technical circles at this point. I'm not going to lock it for now, but I would like to see any further posts more on the value of the KEF, rather than the technical and engineering aspects.
On the upside, I am absolutely positive that this will be the longest thread of all time in the SDC! :lol:

Again, KEF Q100 needs a long burning. And power too. With 80 watts at 8 ohms or more like my cheap tweaked and second hand AV Marantz SR4500.

Hi, I had (still have) a pair of Boston Acoustics A25s and I love how they sound, but wanted to try something else. So I bought a pair of Kef Q100s last week and liked them out of the box; as stated by others before me they're crystal clear, the timing is amazing, the sound of the drums is amazing... but after around 25 hours of burn in I don't know if I should send them back. Yes, they do sound amazing with balanced and punchy recordings, but they're terrible with harsh or poor recordings, and I mostly listen to punk rock so I'm afraid many of my favorite records are unlistenable with this Kefs... the Bostons are much more forgiving with bad sounding recordings, still having decent detail though.
Also, they're positioned 10 cm from the back wall (I can't put them further out) and the bass is boomy with a bunch of songs/records. I had to use foobar equalizer (never used before!) to turn down the 110Hz frequency because the bass was piercing my ears. The A25s had kind of the same problem cause the same bad positioning, but it was a little less prominent.
If I paid $229/200 euros for the Kefs, I would probably keep them, but here in Italy they costed me 300+ euros.
So, my question is: do they really improve that much after like 100/200 hours of burn in? I've only have 2 weeks to send them back, so I can't test it for myself. I've also bought a pair or Tellurium Q Black II cables (used) that will arrive next week; could those cables solve the problem?
My setup is: Marantz PM6006 amp, Schiit Modi 2 DAC, Audioquest Big Sur signal cable.
Thanks!
-
Give it 200hrs. My q100 sounds quite like my ls50 except for the lower end and a tiny more glare for 1/5the the price
-
I don't doubt they're amazing speakers, I was amazed by them just out of the box; I'm just not sure if they're the right speakers for my ears and (a big part of) my record collection. I'd love a more detailed and "refined" sound than that of my Boston A25s, but I also need warm/non-fatiguing/forgiving-with-cheap-recordings speakers too. :duh:

Having listened to low to mid to hi fi equipment (very rarely super expensive) for about 40 years now, I'm fairly sure that this is the trend today > super-detailed equipment, warts and all from the digital source onward.
My suspicion is that since most equipment is designed and manufactured by older males whose hearing is rolled off from listening to lots of loud music over the decades, their preference is for "highly detailed" high frequencies.
-
I would send them back if I did not like them before the owner trial ends. But I have too many speakers that I like now, so I would never buy a pair of KEF's. Bright speakers sell better in dealer showrooms, so manufactures tend to tilt the highs up a little too much.
A friend owned the LS50's, they were not bright when I listened to them, but sounded just OK.
-
I'm going to return them. And then I'll wait to find the right speakers to upgrade my Bostons.
-
..My setup is: Marantz PM6006 amp, Schiit Modi 2 DAC, Audioquest Big Sur signal cable.
KEF Q100 and LS50 love power. The true sensitivity of Q100 is between 84-85 dB. LS50 only 83 dB.
Marantz PM6006: (8 / 4 Ohm RMS) 45 W / 60 W
With this amp you need speakers with 88 dB or more.
-
Now the speakers are longer sold. The alternative, but with rear bass-reflex, is the KEF Q150 (with grill -> more money) (maybe the speaker's suspension will also need a long "burnout" like its predecessor).
I have this VSTplugin: iZotope RX-7 De-Hum (https://www.izotope.com/en/products/repair-and-edit/rx/features-and-comparison/de-hum.html) in foobar2000 (32 bits) and J River MC 24 (64 bits):

Well, I am listening KEf Q150 and Q350 in Youtube and they sound very bad.
https://www.youtube.com/results?search_query=kef+q150
https://www.youtube.com/results?search_query=kef+q350
Surely the same happens to them as in the previous generation: new sound very bad, bright because there are no bass.
The KEF Q100 need a very long burning, 200 hours or more.
KEf Q300, with 6.5" coaxial is worse than Q100 with 5.25" coaxial. KEF Q350? I do not know.
Remember, these speakers LOVES watts. Q100 and Q150 better with SS amps with 70-80 watts at 8 Ohms, 0.1% THD (more watts at 4 Ohms). More true with the LS50 (83 dB/W/m).
Nominal 8 Ohms but I think is more true: nominal 4 Ohms. At least nominal 6 Ohms.
-
About the power we need with speakers with 85 dB/W/m and minimum 3.9 Ohms, I just read:
https://www.soundstagehifi.com/index.php/system-one/1237-nads-d3045-a-d3020v2-on-steroids
New speakers from a new amp?
Although the D 3045’s new feature set is significant, for me the biggest benefit is the power output from the D 3045’s class-D power-amp section. The change from 30Wpc to 60Wpc shouldn’t have amounted to a hill of beans -- no surprise to those who know that every doubling of power results in a volume increase of only 3dB from the speakers. That difference in SPL is only just noticeable, even if achieving it requires substantial upsizing of an amplifier’s power supply, output transistors, etc. Nonetheless, the differences I heard were dramatic -- far more than just being able to play music louder.
The night before I unboxed the D 3045, the D 3020 V2 was still in my system, hooked up to the Paradigm Monitor SE Atom speakers ($300/pair) I wrote about in my first two columns. When fellow writer Philip Beaudette came over, wanting to hear the system he’d been reading about, I played him some tracks. He agreed that it sounded really good -- then said, “What more would most people ask for?”
The next morning, I unboxed the D 3045, swapped out the D 3020 V2, and put on the same track. I got a jolt as if I’d been shocked with 500V. “Rockin’ in the Free World” now thundered with dynamics that simply hadn’t been there the day before. Chad Cromwell’s bass drum hit like a punch in the stomach, the entire audioband was reproduced with much more clarity -- and I could turn it up louder. It was as if I were hearing a different pair of speakers.

83.9dB and about minimum 6 Ohms -> they need similar watts than Q100/Q150, something less.

94db from an 8in woofer in such a small enclosure that hits 50 hz? I'm a little skeptical. I think there's some fine print missing from those specs.
-
Audioholics reviewed and measured them
Hsu reports the CCB-8 sensitivity in half-space at 94 dB at 1 meter for 2.83v, and our measurement of 93.8 dB largely agrees with their specification. Of course, half-space sensitivity converted to full-space sensitivity means a drop of 6 dB, which puts the CCB-8 at 88 dB sensitive full-space by their own specifications. That is above average for a bookshelf speaker, but do not mistake its half-space spec to mean it is a high-powered speaker that can handle THX Reference levels in a large room. The half-space sensitivity specification is simply the result of the setting it was measured in. In a medium-sized room, the CCB-8s can get louder than most people would ever want, but those who like loud-listening in a large room are going to need some much larger speakers.
https://www.audioholics.com/bookshelf-speaker-reviews/ccb-8-bookshelf/measurements
It sounds like they may be imaging champs.
-
Ah, 88db in full space. That makes more sense though the 50hz still sounds optimistic. The 94db makes them seem more efficient than they really are. The 1500khz crossover and coax would give them an edge in imaging for sure.

Add four cheap components but it seems to work quite well. Point of crossing over and slopes remain virtually the same. You can buy resistors say 1R, 1R5, 2R2 and 3R3. Given the tolerances in LS50 drivers i don't expect anything less in Q100. Additional benefit is that you can set the level of the tweeter per your liking.

I don't know how everyone is using there q-100s I have 3 pairs. My local hifi shop was blowing them out for 179.00 cdn.
The smallest amp I have powering them is a onkyo txnr 838. And you would swear I have a small subwoofer in the system (there isn't).
