Vibration Issues / Turntable Decisions

Why not just remodel the whole house?

I’d opine it’s a little more complicated. The resonant frequencies of tonearm, cartridge and platter which are circa 10-12 Hz means they’re liable to be affected by seismic I.e., low frequency vibrations including, but certainly not limited to, those produced by footfall, subways, traffic, and Earth crust motion. In addition, this seismic vibration is in six (count em!) directions, including horizontal plane and vertical and a bunch of rotational directions. Therefore, the walls are moving too. The whole house is moving in all 6 directions! You can run but you can’t hide. Everything is relative so for trampoline floors the wall might very well be better than the floor. But there’s really no substitute for real vibration isolation, i.e., decoupling.

Here are the facts:

The Op initially said the wall mount was ("out of consideration").

Based upon his use of an antiquated console, (which I presumed to be of importance) most here seem to want him to remodel it and affix to the wall. I can only assume his wall is out of consideration as far as hanging stuff on it?

These "initial words" by the OP and the fact that most want to hang onto their money led me to my recommendations.

His set-up is  probably the worst possible scenario. Not only does he have the worst possible scenario for room construction but he has his TT set up in the worst location... right behind a speaker, and then right between the two speakers.

He initially said he was looking for a mass loaded TT.

The main question is, why am I still posting here?

just saw the OP posting about his belt slippage.

Have we’ve been had!

Last time I'll try to help.......

@slaw I think you may find going for a walk may be a good idea. No need to get so mad! OP said he can’t use a TT shelf because of the chair rail molding, which is obvious in the pic. That means he’s still able to anchor the console to the wall behind. Also, the old console looks great, it’s not a surprise he wants to keep it..

And what do you mean people want to hold on to their money? The obvious starting point is supporting the floor from underneath and then securing the console to the wall. There's nothing to throw money at here until he addresses those issues.
