Anyone wish they had a rumble subsonic filter?

I sort of do. I see my woofers moving due to ultra low frequency signal when I play certain LPs. Doesn't affect the sound, but I don't like it. Anyone have a solution for rumble, since modern preamps no longer seem to have subsonic filters? Scoutmaster on a Gingko Cloud 10 on a solid rack on a cement floor, is what I have.

Eldartford.....no but I figure about the price of a Corvette. I am with out a cartridge for the moment, so woofer problems have to wait till I solve that issue.

don't need one because the Bugle RIAA response is 30Hz to 60kHz with a Bandwidth of 15Hz to >150kHz which is gives enough headroom for the sound to stretch out but prevents any woofer pumping.

The Cornet does the same thing: RIAA response is 25Hz to 25kHz. Bandwidth = 15Hz to 30kHz.

The old Audiocontrol C-101 equalizer has a Rumble reducer button(Low frequency summing) and a subsonic filter. They regularly show up on ebay and sometimes here.
