Yeah, they might sound great, but they sure are ugly.
Looks like it came out of the 1930's.
Just sayin'.....
Looks like something granny would put in her ear.

I listened to the Acapellas in Atlanta at AXPONA. I think the initial review was more accurate as I couldn't stay in the room for more than a few minutes with the set-up in what should have been a great room.

"That ionic tweeter offers a high-frequency clarity that is rarely equaled by conventional drive-units, but even at the factory setting, its sensitivity is a little too high for a completely neutral on-axis response."

For all their qualities, I cannot keep from thinking why not audition these speakers with Tact's excellent Room Correction preamplifier, the RCS 2.2x or xp. Granted speakers at this price level ought to perform without it, but if they don't the RCS is made so that tweaking can be made without exchanging amplifiers, cables and such and then really get to evaluate what the speaker could be capable of.
