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.

I have a Musical Fidelity integrated amp-there is no subsonic filter...how about a inline filter to remove rumble...does anyone have experience with such a filter?
I have experience with the KAB rumble filter. I had the same problem in my system with my VPI turntable. The filter attaches through the tape loop and I can hear no difference in the sound quality with or without the filter engaged. It totally stops the woofer pumping/oscillateing.

There was one for sale on here a while ago. I bought mine new from KAB. The insides are stuffed with audiophile parts, so it isn't a cheap piece of junk.

Are your speakers sealed or ported.

This is a very common problem.
