Black is cheaper in Amazon.com. Walnut has the same price.

By the way, yesterday I wrote:

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.

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.

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.

(*) ELAC B6 and Wharfedale Diamond 10.1

Focal Alpha 50 is an active pro monitor.
