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
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.
