Dayton Audio DVC310-88 12" DVC Series Subwoofer 295-185

Not bad @$112.46 each. I'd buy two if I hadn't already sank over $1.5K on car audio stuff this month already. Great bass for the car in about 1.2~1.5 cu.ft. sealed and stuffed per driver, and wired in parallel - parallel for a 2 ohm load to the subwoofer amp.

I've thought about getting two (or 4) of the 15's in the past for a large IB project (I have a "root cellar" that I could use as the box)...

Glad they're not $112, I might be tempted.

I have similar project going on.

Just remember that root cellar enclosure will have some strong internal room modes because all surfaces are very solid.

Neat! That's an impressive amount of work.

My root cellar is ~3.5*5.5*6 feet high. About 3200 liters. Lowest Axial mode of 94Hz. Three walls are unpainted cinderblock, which is an amazingly good wideband absorber. The floor and ceiling are solid concrete. One wall is open, I thought of making a very solidly braced wall/door and mounting the drivers on it.

It could double as a tornado shelter / storage room.

Then there shouldn't be problems under that.

94Hz null in room side will probably just make low-pass filter to work better.
