Unfortunately the table and speakers sit on a big media cabinet from Design Within Reach which is not ideal.Sounds like the media cabinet isn't doing its job. Can you hear foot falls when you walk past the turntable while its playing?
Turntable feedback rumble problems with new sub
I have a Technics 1200 M3D and KEF LS50s. No issues. I just added a REL T7i and have a runaway feedback rumble problem at high volume. I added Isonoe footers to the table which didn’t do much. Unfortunately the table and speakers sit on a big media cabinet from Design Within Reach which is not ideal. Not sure what the right next move is. More turntable isolation, put footers under the cabinet legs, new turntable, new furniture, or new house?

Other than placing the Table in another room its a hit and miss scenario. I assume your not using the table with the dustcover down while playing or have the sub level and crossover adjusted to high? As noted there are lots of tweaks but what many people continue to look the other way from is adequate room treatment which will ameliorate room modes. |
All you need is a couple inches of sand in a box. Pack the sand, put something on top of the sand- can be one big sheet of MDF or four small ones, hardly matters- and put the turntable on that. The footers you have may work better under the sand box, or under the turntable, you will just have to try them to see. If you have the space and the funds you can do even better with a granite machinists plate, which is what my table is on. Between the granite and the concrete rack is an inch of sand. On the bottom shelf the phono stage is on sand and if you look close you will see the square MDF footers the phono stage is on.

@atmasphere Sounds like the media cabinet isn't doing its job. Can you hear foot falls when you walk past the turntable while its playing? Not really, but if the needle is on the record and you walk in front of the cabinet you can see the subwoofer flutter, so it’s definitely picking it up. It’s a wood floor. I don’t have anything under the cabinet legs, which are metal. |
If you have Isonoe it should be fine even if there is 10 000 Watt speakers near. Do not screw Isonoe tightly to the Technics cabinet you will kill its spring effect. It must be like this. Move your SUB somewhere (away from the turntable). |
