    Turntable suspension thread

    Hopefully, everyone can add their grain of salt when it comes to suspending turntables, mainly for dj purpose, but also to get rid of floor vibrations.

    The easiest way to get rid of floor vibrations, I have seen it done a few times, is to install a concrete pad under the floor with a steel pole that comes through the floor to support a table for the turntables. Works like a treat and does not cost a lot.

    Another way

    I've not done it, but one that seems to be popular is to use a "turntable shelf", that bolts to a wall. Seems to work very well, from what I've heard.

    I guess it works too as long as the shelf is innert and doesn't resonate to bass frequencies.

    Hi
    If you are going to mount a turntable on top of some springs or air bags.
    The turntable will want to rock side to side in an arc.
    This is because the center of gravity is above the springs or air bags.
    You should add a counter weight, so that turntable’s center of gravity is flush with the bottom of the springs or air bags.
    This will neutralize any tendency to rock and the added mass will lower the resonant frequency of the floating system.
    Oh, I am joking about the 10 ton weight pictured.
    The correct counterweight value would be the same as the turntables weight.

    As a resident DJ in the early to mid 1980s, my turntables have always been suspended with thick rubberbands.

    Inflatable cushion

    I could be way off but i don't think that inflatables are the way to go. I had a birthday balloon in the house one day and was playing around with it as I was listening to the stereo. I noticed how well it responded vibrationally to the sound waves/pressure in the room, you could feel everything in the music when holding the balloon.

    I have a cheapo CD player that skipped pretty easily. I had some left over gutter foam in the garage and figured I would give it a try. It works perfectly, no more skipping CD's. I also put it under my media center computer, near the stereo. It's strong enough to support some weight, but it's very light and expanded and it's not going to get your equipment hot. Bottom line: I use it, it works.
