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.

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?
 

@slaw Move all sources of EMI/RFI away from the phono cables and phono stage - transformers inside amps will impact it, power conditioners, wifi extenders, power cables. And plug the phono stage and the table into the same circuit with preamp or integrated to avoid ground loop.

Glad audphile1 was able to offer his thoughts...hope that helped resolve the issue.  I haven't ever experienced hum from one channel.  All I would know to do is check all connections and replace cables where possible.

After some trial and error, found out his JC3+ has an issue. Thx for responding.
