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.

Eh... it is with a Nagaoka Mp-500 cart and ortofon mm black lvb 250 cart. The tonearm is stock on the Technics 1200g. These are common carts for the Technics 1200g so I doubt it would be a mismatch. 

The turntable sits by itself on a turntable stand.

Wow, this scares me. Any ideas on what else?

Is that floor suspended? If it is that would cause a problem!

No, is a solid concrete foundation

Also, I get psychosomatic about my speakers. Could I have damage them already? What damage would I look for? Sometimes it feels like the base isn't as tight as it was before. But it could be in my head because I get pretty fanatical about damaging my speakers.

Lower the arm on a record that is not moving and tap the rack that the table is sitting on. Do you hear the tapping? Since you have no problem when streaming I doubt that you damaged your speakers!
