All colors except black. Through the KEF Store @ Amazon https://www.amazon.com/gp/offer-listing/B00CE3LHSK/ref=olp_twister_child?ie=UTF8&mv_color_name=3
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.https://en.wikipedia.org/wiki/Colors_of_noise
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.
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.
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 LS50sBy Jason Diddayon February 22, 2018I 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.
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…
VituixCAD is free engineering and simulation software for passive and active multi-way / multi-driver loudspeakers. It is one of my DIY projects and personal challenge in programming, acoustics and mathematics. Program provides some important features which are not available in all speaker simulators on the market.
Best $250 i've spent on audio thusfarBy James Sasseron April 5, 2018Do 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.
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.
...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.
