Just pulled a pair out of the box (no, I don't own them...just setting them up) the finish is exquisit and they even come with a level on the back end to properly balance the speaker!

Had a wee listen to them...definitely gonna need more power (using a couple Arcam amps currently) cuz they are begging for more juice to reproduce some bottom end. Obviously they're gonna need a good break-in period, but it looks/sounds promising (I guess it should for 24K a pair right??!!)

Besides Kef's IQ series I've always found their speakers to be truly fugly. I like their sound though and they are one of the few I've heard (IQ) that I've considered buying.

You can get a hell of a lot of other good stuff for a lot less than 24K.

Break-in? You're kidding right?

As for amp power; it looks like they are fairly sensitive at 91dB. Nominal 8ohm impedance is not a problem and the min impedance of 3ohm may not be if it hits that in the higher frequencies.

I should get into the speaker business, I guess. Don't get me wrong, the speakers look lovely and I assume they perform well. But $24K per pair? I did a little calculating and my guess is that the speaker systems cost around $1500 to manufacture in 1000 pair quantities figuring just materials and labor - and half of the labor figured in furniture finishing. There should be some serious discounts from list available somewhere along the line, I would think. No?

I guess the only thing that bothered me about the web site is the fact that they put veneers above specifications in the menu. That tickles me a little. I think the specs are honest. 2 10" woofers should provide 26 hz at minus 6 db in an ideal enclosure. I'm sure they work very well and sound terrific.

I don't know the price these days but I once had a pair of B&W matrix 802 speakers that cost me about $6000 for the pair. They had the famous matrix (read anti-resonant) enclosures and a pair of 12" woofers in a cabinet that was very nicely finished, if not as exotically designed as these KEF. They were also a 3 way system instead of 4 but had quality components throughout - with one driver fewer, of course. The sound was as accurate as anything I've ever heard from any other speakers. Those look like a real value to me when compared to these KEF and I'm making an assumption that they will keep up pretty well with the 802 system except in the bass where the 802 will go a little lower.

I'm just saying from an observer's point of view...these look great. They do sound very accurate, just a little weak on the bottom end. 24K is wayyyyy beyond what most people would even look at for speakers...I can buy a nice car for that coin.

Well, I've never understood how people prefer the look of most Kef's; considering I can get the 802D here for about 20% less there's no contest as far as I'm concerned.

Yeah...I much prefer the look of the 802's as well. These KEFs are definitely an esthetic step up from the previous series however.

What I like about their manual is that they list the speaker's MAX spl capability. This will do reference level at reasonable listening distances.:D
Now to overcome that high price:eek:

I agree they are pretty. But should $24K speakers have a weak bottom end?

Like I said, we have them underpowered for sure with the Arcam. Even the N.American rep for the reference line said they like gobs of power. We're gonna try to hook up a couple Krells and see what changes.

I like the looks of the KEF Q and newer iQ ... but these higher end models really look ugly to me. I mean, I wouldn't pay Q/iQ prices for those!

i like the b&w diamond series marlan heads better. these look like cheap imitations.

I like the look of them just fine, it's the price I find hard to swallow. And weak at the bottom end? They shouldn't be weak anywhere with that price tag.

Must listen list when I get the chance

Those speakers are very interesting to me. KEF are a good stable. A coaxial driver has a lot to recommend it, especially for the center channel. See my previous posts.

One of the interesting things about this speaker, is that the two woofers are in separate enclosures with slightly different tuning. I assume this is to spread the area of bass reinforcement. I'm a committed transmission line enthusiast. See my other posts on this. The TLS has broader and greater bass reinforcement than reflex or sealed enclosures.

I really doubt these speakers are bass deficient. As I have previously stated very few people have heard speakers with a really extended AND accurate last octave. People are just used to the horrible problems most speaker create in the bass, that they accept it as "normal." I have found that listeners first impression of a speaker with a really accurate last octave is that it is bass deficient. Also as far as amps go with that speaker, with these two woofers, I bet the impedance drops at the lower end. You need an amp that can supply lots of current to low impedance loads. If you don't have that, I don't consider it a fair listen. Also listen long enough to get used to an an accurate and properly balanced bottom end.

I have a close friend who has just purchased the B & W 800Ds. They are about the same price, but he got the them for $16K. They are very good speakers. Their bottom end was good, but I was aware of the port output cutting in. This gave them a VERY SLIGHTLY heavy footed bottom end compared to my TLS rig, and the owner agrees.

The right and left speakers use three amps to each speaker, one passive and two electronic crossovers. Perhaps hardly a fair comparison. The cost of producing these commercially would be absolutely astronomical.

In terms of cost, have a heart for the manufacturer. The cost of developing a world class design is huge. I bet even with a team it takes a long time. With me working by myself it takes a very long time. I seriously doubt the materials can be provided for that speaker for $1500. I would say that is well under the mark. The labor involved here I would think is prodigious, and we are not talking cheap Chinese labor here. Those speakers I imagine weigh plenty, so the cost of freight must be very significant. The cost does not surprise me at all. Everyone involved in getting a product like this in the hands of the customer has to make a profit, or we won't have sophisticated designs like that. Also this is going to be a pretty low volume speaker at these prices, so there will be fewer units to spread the R & D over. Actually when you look at the history of flagship products, the manufacturer often never turns a profit on them. For instance we now know that Garrard never made a profit on their famous 301 and 401 turntables.

Please keep us posted it you get a chance to hear those speakers with a better amp. Also play some program with some deep bass content, like a big pipe organ with some 32 ft stops pulled!

I feel that the "accurate bottom end" you refer to is just a rolled off response curve and not necessarily accuracy. This is often referred to as "audiophile bass" which is a slowly rolled off response on the lower octaves (3db-6db/oct.) from about 40hz-50hz on down. It is a preference that many people find to sound nice and attribute to "accurate bass response". When a person is used to that type of a roll off on the low end, a system that has accurate, even frequency response down to 20hz or so may sound inflated on the low end to that person. They may say the speaker sounds boomy or other buzz words, when in fact, they are just not used to the properly reproduced lowest two octaves at an even output level.

What I am saying, is do not associate even output response down to the lowest octaves as inaccurate simply because it is not something one may not be used to hearing.

To the OP:

Have you tried messing around with the Uni-balance control for the speakers? It is supposed to help with bass response depending upon room acoustics.

Bass not rolled off.

I can assure you the bass of this rig is not rolled off! The F3 point of the big lines is 27 Hz. The big pipe organs will rattle your internal organs, and it does not have to be at high sound pressure levels. It is just that the bass just flows naturally and spaciously just like real life.

When the owner of the window treatment firm was down he noted that the bass was nice, but he though it gentle and light. He wanted me to put on the battle scene from Master and Commander. He was soon white knuckled gripping the arms of his chair. He had a different view after that. He was the owner of a very good system himself with very high end equipment. He was astounded and thoroughly impressed.

They might make some of the cheaper units in China. But I know for a fact they are still based at a factory on the banks of the river Medway at Tovil Kent, a suburb of Maidstone the county town of Kent. They have large production facilities there.
I grew up about 15 miles from there in the Medway towns.

I remember when Raymond Cooke put his last pennies into purchasing an old foundry there. Raymond Cooke became the development engineer for Wharfedale under the owner and managing director Gilbert A. Briggs. Gilbert was self taught, but still one of the great audio pioneers. He was also a great pianist.

When Raymond Cooke felt it was time to go his own way he did it with GAB's blessing, and they remained good friends. Raymond Cooke moved down from Yorkshire to Kent. When he was sorting through the site, he came across an old casting labeled "Kent Engineering Foundry." The name KEF was born and the rest is history.
