anyone heard zu definition speakers?

Tbg No I have not, I like the Duo's a lot however, but yeah for integration definatly the Zu's are much easier to deal with and more natural I guess, and CHEAPER!! But for the type of package you get with the Zu's I think they have it down pretty good mainly because at 4500.00 a piece where are you gonna get speakers with 16hz bass (4) 10" adjustable, and (2) full range very capable 10's? They are super simple which I like, and am sure the Beauhorns or Lowthers can do a lot of it, but then you get like (1) 9" driver or something in a full range, no matter what they will not compete on the full frequency spectrum or surface area sound up agains 6 10" woofers, but I could be wrong :) Mainly I speak on a value for the money with this, but It all depends on the music you like, I am mainly a Rock guy so Set based amps with single drivers will not perform as well for me is all, but there is something for everyone.

Matrix, the woofers on the Definitions are only from 40 Hz down as I recall. The Lowthers are only good down to about 64 Hz. You do need a subwoofer with them also.

As you suggest, the Beauhorns are not for big group sound such as swing big bands, opera, or symphonies. When I got the Acapella LaCampanellas, I realized what I had been missing in the midbass area.

Tbg, not the front woofers, they are True full range crossoverless 10"'ers and respond from 40hz up to 12khz perfectly, the 4 rear 10's are in fact only 40hz Down on their own amplifier, the supertweeter picks up the range at 12khz up to who knows, but something in the 30khz or something but yes beyond 20khz... they will also put out 130db no sweat, but you will :) So they are basically a 2.5 way I guess would be a good explanation, maybe a 3 way but with no filters. They are super natural and very dynamic and extremly powerful sounding, I would not get into a street fight with them they might punch you thru the backwall.

Yeah, these buggers will play obscenely loud. And, bass doesn't get compressed when they're loud. There truly is no substitute for driver surface area. I live in a 3-story house. The stairwells don't match up. Last week, the family was playing in the upstairs bedroom with the stereo playing in the basement and Jack Johnson was clear. The sound was excellent, not compressed or distorted. Wowsers.

These speakers do something I've never heard. They turn the air in the room into another medium. Not air, not water, the room's atmosphere becomes more dense, like something you could touch and ripple by running your hand through it. Like if it was just a tiny bit denser you could see it. It's utterly amazing.

They won't do this with all amplifiers. My Clari-T with its reduced gain gets it a little bit. The AudioZone AMP-1 doesn't really do it at all, but with the hi-gain Clari-T, the result is astounding. Mine has been sent back to reconcile the gain.

So, I wouldn't assume these will be perfect with every gear combination, but if you get it right, the result transcends hi-fi.
