Great overview, Peter. It sounds like these would actually be reasonably easy speakers to drive - maybe not insanely high-efficiency, but certainly not huge power-hogs like some speakers can be.


This is an interesting question. I wonder how small a cabinet could be to incorporate a somewhat larger driver (maybe an 8" instead of 5.5"), amp, and the "labyrinth" of internal gyrations involved? The question then would be how it would compare on cost and specs to the smaller sealed subs that have been around for years now. If it worked, it would be rather entertaining to see a modest-sized ported sub with an 8" or 10" driver that did things we're used to seeing from monster subs.
