With a .75cu.ft. box I take it you mean sealed. The sub works well in 2 cu.ft. tuned to 22 hz. Here is the WinISD file for the Dayton 10" Reference HF Subwoofer 4 Ohm:

and also the 10" Titanic Mk III

Are there any acoustic disadvantages to making a triangular sub box?

Not really. If porting you might have to get a little more creative. Other then that, just make sure the cabinet is the proper internal volume. Here's a build like what you're talking about only a bit bigger.

You're welcome. Now post a build thread when you get started! :bigsmile:

Good call Phil! I forgot about that one. Definitely worth considering.
