My only complaint of these wonderful speakers is that they cannot be bi-amped, having only a singular speaker connection. I have a Yamaha RX-A810 AVR but I am powering these with an Emotiva XPA-3 200WPC amp. Barring that quibble, they are great speakers. Like another review on this thread, they are not tuned for low bass, but with a high crossover, a subW can make up the difference. I cannot tell this bass deficiency while watching movies, only when listening to music, at which point I change the listening mode to " 7 channel stereo".
