HELP-woofer moves alot when playing lps

Hi-
When I play a record on my TT, I get an excessive amount of woofer movement, even when no music is playing. When I lift the arm off the record with the finger lever, the movement stops, and the phono stage is dead quiet. Its only when I drop the needle and turn it up a bit, the woofer starts to move in and out. I dont get this when playing cds, only lps. I have my system on a shelves, with the table onto and my integrated amp directly under my TT. Might this be an isolation issue? Thanks in advance.

no, just play your music and ignore the woofer movement

It is a problem. Years ago I blew woofers twice on Vandersteens before addressing the arm cartridge mismatch. I use a test record (SHURE TTR115) that will let you know at what frequency the cartridge resonates at. It should be around 12 hz - well below and above the warp region. These are jus the facts my friend, just the facts!!

Yogiboy-
How do I address the mismatch? Should I get a different cartridge? Thanks.

Yes or a different arm.

I solved that issue in my ported speakers (and sub) with some "old stock" Nakamichi rumble filters (30hz) seemingly with no audible effect on the rest of the frequencies...you can still buy filters pretty cheap on Ebay...when I switched to a line stage preamp I bought a Cambridge 640P with its 20hz switchable filter that works really well, again with no audible issues.
