Turntable/subwoofer blues

[Kingman]

I have the dreaded shakes!  When I use my sub and turntable at the same time the sub begins to have a heart attack and overload. I switched out turntables with a little success but still not satisfactory. I have been told a lot of things to do...have some sorbothane coming to help isolate TT. Hard to get sub any further away because of limited space. Any ideas or snake oil treatments I can apply?

Can you wall mount your shelf?   Physical separation of the table and sub is the only real answer.   Taking the dust cover off when you play back can also be beneficial.

No, turntable is in worst place on top shelf of stereo rack which is only about a foot from sub...

a wall shelf would be the best step, but a sandbox might be equally as effective.  Have dealt with this problem myself recently and found that the majority of the problem was vibration through the turntable RCAs.

I have some sorbothane on the way. Hoping this helps.

The whole rack acts like the soundboard of a guitar, sending vibrations into the cartridge.   If you can't move either device, your only solution is to turn off the sub when playing vinyl.

Back in the day some pres would have a subsonic filter on them.   If you could find a pre or an EQ with one that could possibly help you out some.

The sorbothane should work IF the resonance is coming through the TT base. In the short term, maybe adding mass under the table can tame it? Or get real nuts and chain it from the ceiling!

If the bass is shaking the arm, I don't know of a solution for that other than turning off the sub or turning it down.

Chaining from the ceiling is basically the same as wall mounting.   I had a friend who did that in his dorm room.   It worked great.

Unfortunately past the dorm phase 🎶

Not if you're a "slinger"

What about something like this... https://www.ebay.com/itm/1-Harrison-Labs-FMOD-30Hz-Hi-Pass-Subsonic-Filter-Rumble-Reducer-RCA-USA/273442843730?epid=1350975286&hash=item3faa76ac52:g:zZMAAOSwjuFbjx24:rk:6:pf:0

Free shipping.  Sure, looks like an easy fix.     

I am thinking of hanging a shelf on the wall for the turntable, after I decide on the amp/speaker combo once and for all.

It's worth a shot.   In theory it should help.

I mounted a shelf above my equipment rack.
