I don't think you need to waste money on more "vibration control" crap, since you've already gone to the trouble of making a wall shelf. It won't do anything to reduce "airborne" vibration picked up by the table/arm/cartridge. I agree with Amandarae. You either need a rumble filter or need to move the TT further away from the speakers.
How to eliminate TT feedback/vibration
1st Thing I will tell you - I have an OLD TT. It's a Pioneer PL-71. ( I'm looking at a Clearaudio CMB ) My TT is placed out in front and to the left of my left speaker(per Jim Smith's book.) I made a platform of MDF attached to the wall where my TT sits. At no point does the platform contact the floor. When I play certain albums-several in fact, at mid to high db levels, I get either an acoustical feedback or vibration feedback from low hz. I have tried to isolate my TT using something like sorbuthane balls and foam. I have not tried any of the commercial cone devices advertised. (Do they really work and if so-what's the best product?-no salesmen please). I don't know if my problem lies with my TT, or my platform it's sitting on. I have a friend who actually hung his TT from the ceiling years ago, and I may have to do the same. Thought I would inquire if anyone knew the answer before I started experimenting. Will a higher end TT like the Clearaudio cure my problem? Is it the platform I made-or do I simply need some isolation cones?

A sub sonic filter my be needed. As for vibration control "crap", cones could be of great help. I have seen them help in the same situation. I'm not recommending spending a fortune on exotic stuff. You might want to try a set of Dayton dss4 speaker spikes from Parts-Express as feet for your TT. They are really just big brass cones. They are two piece for leveling, but I would screw them tightly together. Use 3 or 4 of them with a tiny bit of adhesive to keep them in place. Worth a try for $15. Another thing you might consider is removing your dust cover and just placing it over the TT when not in use. The cover seems to pick up a lot of vibration. |
Two things you could also try. You could mount the shelf to an exterior wall it should be less resonate and if you are feeling handy you could build a TNT sandblaster both have worked quite well for me. http://www.tnt-audio.com/clinica/diyracks.html |
