    Default Does anyone have recipe for homebrew cabinet dampening materials or paint ons ?

    Does anyone have recipe for homebrew cabinet dampening materials or paint ons ?

    years ago I redid a set of Genesis 2+, and painted the insides of the cabinets with a product
    called 'silent running' it is used on engine compartments to reduce vibration../ noise
    I received a gallon for a very moderate price..

    but now it is $150/gallon

    any ideas ? rubber cement with birdshot ?

    Are you trying to add mass to the cabinet walls, or just damping material in general?

    Blackhole and other foam options seem very expensive imo (i'm not being cheap)
    But the silent running seemed to work well, and did add a little mass to the cabinets...

    Just want to duplicate the blackhole soundsheet effect

    What speaker are you using them on? You can over do it with Blackhole type sound deadening products.

    I don't think you'll come close to duplicating what Blackhole does with something that you paint on. Bite the bullet and get some - $60 for a sheet big enough to do several pairs of speakers. Remember, you don't cover the whole inside of the cabinet. You use a 4"wide strip on the back wall across from the MW. Some folks also put a strip on each side wall.

    I've used the rubberized with rubber pieces non-slip coating before on driver baskets. It wasn't expensive, but didn't work as well as the purpose built stuff either after two coats.

    Second Skin makes very well respected products in the car audio/show car/hot rod community. Not sure how well it will work for an enclosure but call them to see if it will work. Their Spectrum coating is $68.60 Gallon: http://store.secondskinaudio.com/spectrum/

    This company I have never heard of, ACRY-TECH Coatings but the Acoust-X Sound Damping is $26.95 a gallon:
