MTX 15 with upgraded amp (the MTX died, put in a monoprice 200, IIRC)
Infinity Mains with a 12 in each.
basically, the mains provide the "musicality" & tone, and any bass image steering.
the MTX is corner loaded and is a JACKHAMMER for the last few hertz of gut churning bass.
it is amazing to me how well it works together, invite some other guys to come critique it. it really blows away everyone who comes over.
outside the house, it sounds like a car stereo driving by, with the pounding bass & muted high's
