Has anyone heard the KEF Q900 loudspeakers?

KEF Q900 2.5-way Q Series floor standing speaker with Uni-Q array - $1,800 pair

These speakers look interesting to me, but I have no way to audition them. I was wondering if anyone knew at what frequency the 8” Uni-Q midrange unit is passively crossed over to the passive radiators. I would guess around 100HZ. Does anyone know for sure?

Am I correct that there are no KEF dealers in the USA and that now KEF is a direct Internet sales product mass produced in China?

The design looks like it should have very little crossover distortion and they have saved costs by avoiding real wood veneer and by using a rectangular box instead of the fancy curved boxes so common these days.

Does Pioneer, Polk, or other cost conscious manufacturer make anything better that is available on the Internet for $1,800 a pair?

I heard a 32 mm aluminum dome tweeter I liked on a Celestion mini-speaker back in the late 1980s. The 38 mm aluminum dome on the KEF, I hope, may be even better. I think the added surface area makes for a more natural sound. Aluminum dome tweeters have gotten allot better lately, and I was wondering if KEF had cured the hard, steely, cold sound commonalty associated with aluminum domes.

If I purchased a pair I guess I would have to do it deaf, as there is no way I can audition a pair.

Comments?

Yea, I know, but there is a point where the midrange unit naturally rolls off and the passive radiator passively rolls in.

The design is strange in that they have a real dedicated woofer driving one passive radiator and the second passive radiator is energized by the midrange unit. They have separate sub-enclosures. That crossover point requires a low pass filter so the dedicated woofer does not produce midrange sounds.

I am guessing the midrange unit is designed to roll off at about 100hz.

The only Uni-Q speaker I ever heard was the original version back in the 1980s I guess. It had a 8" black plastic cone, but I do not remember what the tweeter was made out of. I listened to it off-axis and did not like it at all. Your reasoning sounds about right. Thanks for the warning and the reminder. They use a similar design on the TAD speakers which cost as much as a house. If that speaker also has that problem, I do not understand why people would buy it.

For wide dispersion the best combination I have found is to use a 5.25" cone midrange combined with a 1" dome crossed over at 2,000 Hz. That gives you a wide dispersion point source.
