Vibration problems

dylan Posts: 453
Ever since I got an SVS sub, DVD's skip during heavy lfe. CD's seem ok on heavy bass stuff (on a Denon player), but the Toshiba 2715 skipping is really annoying. I put the player on 2 towels (the towel mod, patent pending!) to make sure it was just the vibrations, and it played fine, so I'm blaming Toshiba for not being very flexible.

So... Vibrapods cut it way down, but it still happens. So usually heavy lfe parts are the exciting parts of the movie, so bam bam bam -- skip -- silence -- silence -- and it moves on. I also just bought a new equipment rack, with the stands filled with sand, but it did the same thing on my old stand.

Any ideas for vibration absorption? Foam? Dynamat? Styrofoam? Vibrapod sandwich?

    Did you bake the vibrapods?

    You actually might want to try adding some weight to the dvd player. Get a $2 mousepad, set it on top of the player, and add a 3-5lb weight on top. You can deal with the 'ugly' factor later, I'm interested to see if this helps.....

    Try "Big Feet" from Audioquest, made from sorbothane gel. This solved all my vibration problems.

    I'd look into a piece of rock. Granite, slate, or marble for under your sub. Put this on top of those towels and your problems should subside.

    Wouldn't that create a "HARD" sound?

    I've never heard of soundwaves being hard or soft.

    You're just in that F1 mode. That's okay. I'll be here.

    It was meant to be a pun, but you can have a hard or soft sound depending on room acoustics, etc.

    From what I've heard/read from people that use a downfiring sub is that this kind of treatment is THE way to go. Front, side, & top firing subs can also benefit, but not usually to the same degree.


    If I had a sub with a sound that I considered to be 'hard', I'd be a happy camper.

    Do you use a "stone" platform?

    Nope. I use spikes. But my sub is a front-firing design with smaller drivers. I'm also using this in a pretty small room with a wife that has the hearing of a bat and a daughter that sleeps like a shrew. Until recently I also had a tenant living upstairs.

    If possible, as scott suggests, move the sub farther from your rack.
    Also, get some foam.
    I'm using 1/2" compressed closed cell foam under my subs (front firing) and it helped alot.
    The sound is still big and deep, but the lamps no longer rattle.
    For a down firing sub, I would put a piece of stone over the foam. Insulating the sub from the floor, but bouncing the sound up into the room.

    Thanks everyone for the suggestions. I tried a bunch of weight on it last weekend, but no luck. I thought that was going to be the ticket.

    How far do you think the slate should extend past the sub? The foam sounds good too... is that a Home Depot kind of deal?

    Thanks!

    As long as the sub sits on the slate, it does not matter how far out it extends. Your landscape supply stores will carry the slate. I picked up a 2" thick, 1.5' x 2' slice for $20. Of course, I did this for increased preformance from the sub, I did not have any skipping problems.

    Good Luck! Have you thought about putting the player on spikes?


    Peace Out~:D

    I picked up my foam from REI.
