Well if we're gonna start showing off... hehe...
This is what I have now. Keep in mind my living room is only about 200 sq ft.
My fronts and rears: JBL S-38's
Center: JBL S-Center
Sub: JBL PB10
I spent about $950 to snag all of this, and in my humble opinion, sounds fricken awesome. As Leon once said, it is very important to have matching fronts and center, and I feel rears as well. My rears are a little overkill yes, but hot damn they make up for it in sound...
