Does anyone use a RUMBLE filter?

I am having way to much cone movements on my main speakers and Sub when I play vinyl. Someone suggested I purchase a rumble filter from KAB audio. I notice that a lot of the cheaper phono preamps have these filters built in. When I purchased a more expensive better sounding unit ..it dosent have one. So I am wondering why dont a lot more companys sell these things if they are so important? I need to buy one and they dont seem to be very expensive $170 + another IC cable.

IME the most frequent cause of 'woofer pumping' is an arm/cartridge mass mismatch. This problem should be cured by proper matching and set up, not a rumble filter.

A rumble filter would help with sub-sonics that are present on the recordings. I've heard these on some British recordings where the studio was near an underground/subway. But I'm not so sure they are all that common. If you have a tape loop on your pre-amp you could stick one there and only use it when needed.
