I have a pretty generic sound system.  I have an RCA pro-logic surround sound receiver with pro-studio front's and rears.  While I have thought about purchasing a new system, I have come to the conclusion that for now this does all we need it to do.  It does help when you have pretty terrible sounding theater's around you (it makes your sound system sound so much better :>)

Here is my RCA Pro-Logic Reciever.	I have 2 of these speakers for my fronts and they are as big as they look
	I have 2 of these for my rear speakers.
