Axiom Home Page Forums General Discussion Advice from Axiom Owners What speaker for sixth channel

A single rear without the sides would end up missing a lot of content. It would be up to the receiver to detect a single surround, and then run in the old Prologic 4.1 mode. I don't think any current models do that. But if you picked up an old non-II model, it would work to hook up just a single surround and feed it with matrix stereo audio only. (It isn't much of an option, really.)
