Turntable - On the Wall or to the Floor?

Thanks everyone! Sounds like the wall.

There is another solution that I have used when faced with a flimsy floor which transmits footfalls to the turntable - hang the turntable from the ceiling with 4 guy wires attached through turnbuckles attached to a large shelf. The turnbuckles are used to level the table.
I placed the shelf-turntable assembly close to a wall where horizontal sway could be controlled through two small springs located horizontally between the edge of the shelf and the wall. Works great. My turntable is an Oracle Alex III. The effect is quite stunning, also, since one cannot see the guy wires, so the turntable appears to be 'suspended' (excuse the pun) in air.

Salut, Bob P.

You know that's funny that you mention this method. Years back, I remember reading an article...I think it was Stereophile...he talked about such a method, saying that the best possible isolation would be suspending the table in space. Did you read that back then?

Anyway, this won't work for me because the look here is old farm house. I'd probably get divorced and have to move out...wait...then I'd have a new space and...hah...hah!

But, in another room. The wall is best but if you keep it in the same room as the speakers, you still get airborne vibrations unless you acoustically shield the tt. Footfalls are a small problem compared to the airborne vibrations.

Another approach which may work for you is to strengthen the floor from beneath. If there is a basement or crawl space, it is not difficult to place a beam across the middle of the floor, one under the speakers, and one under the TT.

The beams should go perpendicular to the joists, and can be held in place with jacks which allow more or less tension to level and dampen the floor. This serves to reduce the natural reasonant frequency of the floor thus reducing vibrational displacement. It is a relatively inexpensive approach and if you are not satisfied you can retreat and try something else.

I did this on a second floor living room over a garage, and it worked extremely well. You could dance on the floor without any affect to the TT. I would also recommend putting the TT as close to a wall over a foundation or load bearing wall as possible, as this is where the displacement is the least.
