Hi,
In my music room I have a pair of beolab 5 speakers, I have a wooden floor and in between the speakers I have a wooden sideboard unit with a technics 1210 mk2 turntable.
I get quite a lot of vibration feedback from the beolab 5 speakers, the bass goes straight into the floor, then goes up the wooden furniture to the turntable.
Because of this I have stopped using my turntable and reverted to cd's and digital media which obviously doesn't have this problem.
I have goggled the issue, what seems to be the answer is to put the turntable on a wall bracket/shelf as you need to stop the turntable getting the speaker vibrations.
Has anyone had this problem? the turntable already has good anti vibration feet, has anyone got any good ideas??
Thanks
Old dog. Old tricks. A relatively cheap (USD20) thing to try is 1/2"-3/4" Sorbothane mat. Not pretty, but at least they come in little black pads now instead of the huge ice-blue floppy mess of yesteryear. Actually, the Technics turntables were stiffly suspended, compared, to, say, an old AR turntable that was tough to get to stand still! So a simple set of pads will probably do the trick -- unless your bass gets so loud that the acrylic turntable dust cover starts to act as a microphone! (Don't forget to check it for level afterward, because: cheap pad manufacture, uneven TT weight distribution, etc.)
More expensive, if you're in the UK like so many on this board, audiosuspension.com is in your neck of the woods and is BeoModerne. Or search the audiogon forum; keywords "suspended turntable". Amazing discussions about whether the air-pressure suspension rigs make too much noise while floating your turntable, or how to calculate the compliance of springs per the weight of the plinth...
(Edit: Don't hit me, but just to be sure: Technics SL turntables originally shipped with a screw underneath, 4 frosted-clear plastic corners, and 2 pull-tab plastic half-rounds, all of which had to be removed. If you've owned your SL since forever, then just ignore this needless warning -- but if, for example, some newbie left in the 4 corner bumpers/wedges, the plinth would be awfully well-coupled to the base!)
I had the same problem with a Beogram 4002 and Linn Axis - in the end I moved the Beogram to the side of the speakers and this cured the problem - doesn't look as nice though! - I had thought of putting concrete slabs under the speakers (M100-2) but not sure if that would help. I did try a marble slab under the turntables but that didn't do much either. Floor is also wooden and the speakers either side of a fairly solid hifi unit.
BTW the Axis is my spare in case the BG goes wrong - can't tell much difference between the two but the BG beats it on looks and ease of use.
