Is it possible? I got swallowed up by the new fad a while back, but I am only concerned with 35Hz on down. I know these tapped horns are amazing, but I don't like how they perform better as you get higher in the FR. If I build one large enough to go low enough, this might just be my thing. Otherwise, I am still looking at dual 21's in 128 cubic feet each, 16" port each, 10Hz-15Hz tune. The portion of the room I'll be placing them in is over 8' x 12' in a 4' section... actually a little over 6" play in each direction. Is that big enough to be able to implement such a driver with such a bandwidth?
