Turntable Causes Speaker Cones To Excessively Move Rapidly

I have a Technics 1200G turntable, Luxman 595, and I use MM carts. For some reason, when I play my turntable I see my sub woofer cone (REL sub) and my Focal Sopra N1 cones move violently. There is a subsonic filter on it where helps cut down on it. But I am wondering... does anyone else have this issue?

If I didn’t have the subsonic filter would the violent moving of my cones damage my speakers? I ran it for about 2 hours total of turntable music before I noticed. 

Not a issue with my streamer... they stay almost perfectly still. Just with turntable.

I just made a mismatch of an excellent high compliance cartridge (V15VxMR) on an arm made for Medium Compliance Cartridges. I didn’t realize my prior arm (SME 3009 II) was an ideal match for that cartridge, I had just gotten lucky.

OK, so, now unlucky.

I decided: solve the problem, learn something, I encourage you to let us know what tonearm you are using, and get some recommendations of cartridges for it.

My local friend just returned from having his Rega RP10 fitted with his supplied 

low hour Ortofon Cadenza Black lomc. 

Experiencing hum, right channel only. 

Thoughts?

Had the exact same problem w my Linn LP12 Klimax (and Wilson Alexia speakers).  A $180 Kab RF1 subsonic filter did the trick.  Sounds identical with/without but it stopped the woofer rumble.
