He has also chosen 3 subs using different crossover regions with each sub, this sounds like a pretty extensive DIY project or at the very least a lot of research to get the correct subs so they will play nicely together.
I think the majority of us are just looking to plop something down and have it play smooth with very little effort.
Those are good points (among others you make). I don't know exactly how Dr. Geddes makes his living, but I get the impression he is a pro at speaker building and room setup. When he says his subs are inexpensive, he seems to be counting up only the costs of materials, because he makes them. They might seem pretty expensive, to me.
And I agree that his methods take more equipment, time, and expertise than I, or many of us, could muster.
