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.
@audphile1 I tried an experiment. I only used one speaker furtherst from the turntable. I had my sub off. I still got the woofer excursion on that single speaker that was on....so I don't think it's coming from the speakers or sound waves.
Could the lid on my turntable be causing it? I tried it with lid closed also and still had the problem. |
Try this @dman777 put your table and luxman on the floor in the center between speakers run just the table no digital. No sub. See what happens and if it still continues there is nothing much left to suspect besides mismatch between table/arm/cartridge/phono stage

@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? |
