Just toying around with ideas, as usual, to get a feel for what each alternative for the new HT would involve. For the moment, the idea I'm toying with is magnepan's all around in a 7.1 setup. Assuming I already have a really nice sub system in place to handle L/C/R lows + LFE information... I'd be using smaller magnepans for side and rear surrounds - MMG's or SMGc's most likely. These speakers certainly need low bass suplementation, and can actually use some reinforcement up to around 120Hz or even higher. For HT I'd just set them as small, and live with the minor directional cues being sent to front L/R or sub at these mid-bass frequencies, but I'm more concerned about multichannel audio. I'd hate to have a trombone that should be in the rear corner sound like it's coming from up front. OK... so, supposing I wanted to add mid-bass reinforcement to each surround channel, to keep directional cues intact, what would you recommend? Assume I already have amplifier power to spare (I actually have four spare channels at 130w/8ohms, so that part is taken of), and suggest something for the actual driver and enclosure. I've never really been a fan of ported enclosures, and I don't think they would be the best match for magnepans, but if you disagree tell me why. If you think sealed is best, what size/brand driver? I could still cross over the lower frequencies and pass them to the sub system (say, somewhere between 40Hz and 60Hz), so low end extension wouldn't be a primary concern. I would be looking for something that is accurate, flat within the ~40Hz to 150+Hz range, and clean. Good phase characteristics (active crossover suggestions are welcome), etc.
