Any subs that calibrate for the room?

Joseph Audio's new sub does. Not sure about any others.

Velodyn has a nice pricy new digital subwoofer that does this. Havent heard it myself, but i hear it is incredible.

there was a thread about a month ago with a title something along the lines of "Throw out your subwoofer" or something. Do a search vs Velodyne, apparently this thing has some real good calibration functions

This assumes you like the calibration assumptions made by the designer.

calibrating is so easy, there's really no reason to break your neck looking for self-calibrating speakers or subs. Don't know that I would trust it
to be set correctly for the room, etc. If a goof like me can calibrate --
believe me -- anyone can.

What you *should* be looking for is a sub that gives you the ability to
integrate it into your system, with control over crossovers, and maybe an
equalizer to set it to room your room. In that case, I would choose a
Revel B-15 performa. Great Sub. You can calibrate it yourself or, if you
buy from a dealer -- have them come calibrate your system for you.
It ain't hard to do. I know, I know...I already said that above.
