Has anyone built (or tried to build) an Infinite Baffle subwoofer? I could use our laundry room as an IB but I think this type of project is too much for me.

A buddy of mine mounted two 12 inch subs in his ceiling, so his attic is the IB.

You know, I always wondered about the backwave on those attic IBs. Does the whole neighbourhood hear a whump thumpata-whump coming from the roof of your house?

Yeah, I'm pretty sure most eave vents are not flared or vortexed, so they're bound to chuff badly.

maybe sound coming through the roof sounds better than coming through the walls.

I never thought to walk outside when he had it going. But now I want to.
