Okay, just checking. I've got a couple of 12" subwoofer drivers sitting idle in the blackhole that is my hall closet. One of these days I'll get somebody to build a couple of enclosures for them. I do have an active crossover and power amp sitting around too, so maybe I'll try out stereo sub thing.

But I think that is a separate issue from the whole large/small vented/sealed speaker issue that made me post my initial question. I was hoping more people would respond. Guess I'll just continue to wonder why folks set their systems up as they do.
