I'm wondering if I could use my HT receiver to also drive other speakers spread out across the house for music or whatever. Is that even possible? (I don't have a particular receiver yet, but take something like the Pioneer VSX-74TXVi for example) Is it possible to output audio to just the other speakers? Both sets at the same time? I know most receivers have a 'B' channel for the fronts, but is this good enough to power multiple speakers at the same time? Would I just run regular speaker wire to the additional speakers to power them, or is something else needed to power them?
