Excessive woofer movement with a VPI JMW 9 ?


Anyone else experience excessive woofer movement with a JMW 9 tonearm ? I guess it is rumble. I've heard it is endemic to arms with a single point of contact. Just wondering if anyone had any solutions. Thanks

I've owned both the KAB and DB Systems units in the past - both effective without any negative sonic impact to my ears.
KAB rumble filter worked for me too. HW-19, Audioquest arm and Sumiko Blackbird, Wright pre/phone.
Thanks guys. I had a local guy (Morgan Sound, seattle...really great techs by the way...) build a 20 and below filter for my sub, which is where i had the problem.
It worked great. Thanks again. sm2727
Ported speakers or ported sub + vinyl = subsonic filter. It doesn't matter how well the cartridge is matched to the tonearm or how well the table is isolated. You will benefit from a decent subsonic filter.
