Oh yeah, and it probably won't be a sonotube - I've got a bud who is putting together a room, and I owe him a present... This'll be my first (electronic) project, but I've built (some nice, if I say so myself...) furniture before. I figure I may have $25-30 in the MDF at the most, right? Which basically leaves the driver, and maybe $25 or so for wire, laminate, plugs, feet, etc.. So - What driver would you go with in the $200ish range? Or cheaper, if it'll work - hey, I'm not proud. He'll probably be running it with half of a Phase Linear 700 (the other half should be destined for the center channel), unless someone tells me that this is a Bad Idea.
