I am definitely going to try multiple subs, having followed the discussion concerning them by both you and Earl Geddes. I have assumed that corner mounted woofers with a time-aligned playback above 250hz or so was the best possible (ala TacT/Lyngdorf)-- but that may not be the case below Schroder frequencies.

Thanks also for the various plans. I admire your approach to bringing good sound to the non-engineers (includes me)-- and your "good value" approach.

Time to get some enclosures built.
