big Stereo speakers for surround back?
I have these old Kenwood stereo speakers and I have been trying to set them up for surround back due to the lack of bass in my original surround back speakers. I hooked the Kenwwood speakers (they have 8" woofers with a 1' tweeter they can handle 100w) to my onkyo receiver which can handle 130w per ch. and they dont sound loud like my the rest of the system I had to go to level CAL and put down the volume of the rest of the speakers (front right center surround r and L) so that I can hear the Kenwoods. But the volume between the surround backs and the rest is to wide it I have to turn the receiver gain almost all the way up so i can heear them . I know its not the speakers because they sound very good in there kenwood stereo receiver.Is there anything in the receiver menue I can do to enhance the surround back speakers? Is it even a good idea to hook up stereo speakers to surround sound?
