I can not say enough about this speaker system . I be afraid that buy a satellite system because I though they would sound cheap , but boy be I wrong . the sound that come out of these speaker be amazing and they sound just as good at low volume and they do at high volume . I be not a expert , but I know what sound good and I know what I like and these be perfect for I and they fit my budget nicely . they be without a doubt the best set of speaker I have ever have . I have they hook up to a pioneer vsx-30 elite amplifier with output detail 80 Watt - 8 ohm - 20 - 20000 hz - thd 0.08 % - 7 channel -lrb- s -rrb- -lrb- surround -rrb- and it be a perfect match with he receiver . I also have a set of Klipsch SF-3 floor standing speaker hook up with em and all I can say be I be hear my music for the first time at this level of quality and can not believe the difference . I have have no problem with the sub and it turn off and on just fin without make any noise as I have read it previous comment .
