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 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.

I said in a previous answer I use the KAB rumble filter. I consulted the manufacturers of both my turntable and speakers, and after I told them everything I tried, other than changing the cartridge and or arm, I was advised that the rumble filter was the best option without degrading the audible sound quality. The speaker manufacturer told me you can severely damage the woofer if it oscillates so much that the woofer cones exceed their parameters.

Try out the KAB filter, you have nothing to lose. You can always return it within 7 days or sell it here.
