I had exactly the same problem early on. Turntable & rack isolation cured it.
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.

@dman777 , I used a ZU/Denon DL103, Gold Note Vasari Gold MM cartridge and a Benz Micro Glider. Same happened with all of the cartridges, excessive woofer pumping. I tried 3 different platforms for the Prime, a solid granite sitting on Cones, a large base custom made by Audiophile Vibration Control and a Mapleshade platform. Nothing helped except moving the turntable to a different room. My Technics SL1200G has excellent chassis damping and all the cartridges mentioned work very well with the Technics. |
@andyhifiman can you tell me please, was that a techniques turntable where the screws are loose? And what model? |
Hello dman777, In my situation I am using a Clearaudio Performance DC turntable with a Universal 9 inch tonearm and this happens to be a belt driven model. The issue in your case may still come from some part in the turntable not properly affixed. Yours being a direct drive turntable may still have something loose or rubbing against another part. |
@andyhifiman if I can ask please, how did you find out? Did you take it to the shop and they found the issue? Was it the original place you bought it from or a repair shop? |
