I have recently installed a 7.1 channel setup of Definitives: UIW
75s for the front and for the rear centers,
UIW BPZ/A rear channel effect speakers, and a C/L/R 2300
center. (I already have a 15" powered sub.) I am
driving these with a Yamaha RXV-995 5.1 channel amp, but
have planned the purchase of a B&K AVR-507 in January.
Quite simply, these speakers are amazing! The depth of the
C/L/R 2300 has to be heard to be believed. Resolution of this center channel
is nothing short of amazing. The UIW 75s are great for home theater, but
are also very fast and musical. And the UIW BPZ/As... These things create
a soundstage that is massive! Run and get these things for yourself.
