Subsonic filter noise??

Greetings. I just recently wrote about some questions about my Linn Axis. Basic Plus Tonearm and Signet MR/ ME cartridge (AWEFUL).

Another problem that I have encountered is that I have a lot of subsonic noise. I don't particularly hear it, however the drivers in my speakers move a lot even when playing at a low volume and I am afraid I will damage the speakers if I turn up the volume slightly. I am using an Aragon 47k from the mid 1990's which does not have a subsonic filter switch and I think it sounds OK. The rest of my rig is: Classe 6L MK II Preamp, Krell KAV 250 A,
Pioneer TAD S-2ex (amazing speakers and very underrated). Cardas Cross By wire speaker cable and miscellaneous Audioquest cables. Can you buy a dedicated subsonic filter or should I look at another phono preamp with that feature?? The 47K has variable gain and load adjustments but no Subsonic switch.
I am considering a new cartridge and was wondering if this would eliminate or alleviate the problem.

Thanks in advance.
