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?
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.

@slaw I don’t have my table on the floor behind the speaker. It sits on solid steel amp stand between speaker and integrated. Concrete floor. Zero issues. I do plan to move it out of there eventually but I’m not in a hurry. The Sabrinas are rear ported. They are placed about 4ft from the wall and there are bass traps behind the speakers. It’s all taken care of. To add…there’s no defined rule for a best place for a turntable. Wall mounting eradicates issues with suspended floors but the bass that travels along the room boundaries might still impact it. Heavy table on a rock solid stand is the key in addition to finding a good location. |
@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. |
Thx for your replies @audphile1 😊 |
