I've been reading up on subwoofers and need some guidance on the best hookup method. My receiver has one preout for a subwoofer (im guessing its LFE) and I've read this is the easiest way to hook it up. But does this send bass to the woofer if im listening to stereo sources or does it only work for digitally encoded 5.1 surround sources? I've also read that you can connect your speaker outs to the subwoofer and have the sub decide what to send to the mains. Is one method better than the other? Any help would be appreciated. Thanks, Paul.
