30Hz

30Hz will work. They also have an adjustable one with 4 or 5 settings (also with 30 Hz). Only issue with the Harrison as a stand alone is the shallow filter (12dB per octave). When used with some of the other amps with preset 28 and 25Hz filters (RF and Kicker) that are 12dB they work well as an eliptical filter. 2 Hz off from 32 to 30 will be good considering its 12 dB. Rather it be 24... but not the case.

No one really seems to make a stand alone subsonic filter... easy enough to do, but nothing really out there.

earthquake amps are really underrated, i would've gone with something else. as for the filter i would defintly go with 30hz.
