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 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

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.
