I have these these hooked up to a Denon x4800 AVR. I bought 4 and the center channel. After adjusting the speaker angle and distance from the wall and using the Audessy room correction it has been fantastic. These can really crank up I pushed them past 100db and they could likely go even higher but my Sub was already struggling to keep up. I got these for $489 a pair which is a great deal. Some reviewers say they are a bit too bright but with DSP/equalization you can level these out to your taste. I'll be rocking these until they die.

Decided to upgrade my nearing 20 year old Home Theater System and went with a KLIPSCH all around speaker system. These bookshelf speakers a larger than the picture make them seem. Be prepared to house these monsters on speaker stands as wall mounting may prove challenging to newbies. The speakers sound really good and even have a bit of a bass feedback reverb. I did a calibration test and they actually have decent sounds they are able to process. These have a bit of weight to them also.
