Apogee Acoustics Synergy 1.5

[E-Stat]

However, let Joe decide what he wants and can buy. He loves Apogees and Acoustats but the smaller E-Stats dont have the bass and the big ones wont touch the bass region of the Synergy or the big ones and a dynamic subbass system is very difficutlt to integrate unless you go to length like some do.

Now we agree. As for me, I find response down to 24 hz in the U-1s to be sufficient. Coupling direct radiator dynamic subs with bipolar planars makes the coherency issue even more problematic.

SL's answer for bass freaks is adding a pair of UB-1s. They are electrostatic subs using the same steel frame, but with thicker diaphragms and greater stator spacing for more excursion. They have the same 82" height, but are a touch wider. They are the units in the center of the pic.

I know the UB's ;-)

But there we have the problems with the room size and acoustics, time differential and phasing issues. Nothing is perfect, but for me a system needs to do 20Hz flat and below with pure raw power. The Grand moves a huge amount of air just for 250 to 70 where all the acoustical power is. A fascinating system :-) Not to mention the fully activated system and no passive components.

All large systems require space for optimum performance, especially bipolars. I suspect the Grands were likewise intended for a large space.

No doubt. HP's big Nolas are likewise very entertaining since they are flat to about 16 hz with their eight 12" drivers driven by a separate amplifier.
