Hey anyone sell a varible subsonic filter?

Not sure if you can just buy a standalone subsonic filter.

You can use the Kicker KX3

Or this: http://store.xmfanstore.com/linedriver.html

The old Phoenix Gold Bass Cubes had a subsonic on them as well, fixed @ 25 hz.

It is also a bass boost, so just wouldn't want to use that part much. The subsonic actually has a switch between fixed at 25 hz or variable at 1/3 octave below where you set the bass boost center frequency at. Interesting feature/idea, but I'm not sure how practical it is. I guess you could just set the bass boost frequency wherever you need it to be so that the 1/3 octave below is the subsonic crossover frequency you want, then just don't increase the boost.
