I'm building a home theatre 30'x 22' x9.5' and want to use one of the 22' walls between theatre and mechanical room for a house wrecking sub and want true infrasonic capability. Was originally lookin IB but thought having furnace in room with that much air displacement might lead to bigger explosions than planned. Do you have any thought, suggestions, ideas, recycled plans? Oh,also liked what was said about fast articulate, effortless sound of horn. I have dipole speakers at the moment that don't marry well with most box subs, just makes mud.
