Thanks sholling.....the review models look close enough to the present models to get the idea...the tweeter control is interesting....perhaps if they discounted these things, a few folks would take a shot....per my audition, I was impressed with what seemed to be a high efficiency with loud sound at -35 on a Yamaha RXV 663 modest amp....The owner used 3 of the identical units for R, L, and center....the identical center being another unusual touch....
