Jim, would it be feasible to build passive sub modules to be used as stands for a pair of sealed HT2 monitors, similar to the ones you made for mpd's HT1s, using Aurasound 15'' drivers?
Sorry for the delay. I knew I had read your question but didn't have time to answer at that moment. Ever since, I was wondering where that question was (email, forum, etc.) since I didn't recall ever answering it.
Sure, it would be feasible and certainly could be done. The first question, though, would be how low you need the system to go. If an F3 of about 18Hz is low enough, I may have a better solution. If you would like to email or PM me, I would be happy to explore things with you.
