    Lining an enclosure with sound deadener

    *Crazy idea #1274*

    If I line the INSIDE of my enclosure with sound deadener, what kind of change would I notice?

    MDF is self dampening so you dont "need" to line the inside. as for any spl gain probably nothing to minimal but i could be wrong....

    Re: Lining an enclosure with sound deadener

    and no i havent done it. but why dampen something that already dampens itself?

    wouldn't that be like putting fiberfill in it. same idea.

    for ported, I dunno, seems like it would screw up the port by hurting the airflow.

    Re: Lining an enclosure with sound deadener

    So it's never been tried before? Ok, I might attach a layer or two to one of my enclosures, see about any difference. Fill you in. I have a rockbox m103a amp to install tomorrow, too.

    I asked, because sound going from the back of the box can cancel out sound from the speaker, it's why the sound better facing backwards than forwards. (someone tested this, I found the link on one of the old threads)

    So, if I were to line that, super-deaden it, there'd be less vibration from the back of the box to interupt the vibration from the speaker. Means (potentially) clearer, richer, deeper bass.


    ... Why is rockbox in red? Nevamind, put it in search looking for review(s)..

    I think you are misinterpreting what was said in THIS LINK. The incident wave (the red wave) isn't the sound coming from the back of the box, it is the sound radiating rearward from the speaker.

    So, if I were to line that, super-deaden it, there'd be less vibration from the back of the box to interupt the vibration from the speaker. Means (potentially) clearer, richer, deeper bass.
    There are benefits in having a sturdy box (which is why we use .75" or greater MDF), but you'd have better resonant killing properties by layering up the MDF (making the walls twice as thick with the MDF) than trying to layer on sound deadening IMO. You don't want the box to flex, that's a given, and can achieved either by using internal bracing or, as I mentioned, doubling the thickness of the walls of the enclosure.

    Re: Lining an enclosure with sound deadener

    I was thinkging of throwing some sound deadener on the inside of my ported box, but was told that it would affect the tuning.



    HU: Apline 9815
    Sub: Image Dynamics 12 v3 @ ~ 28 hz
    Sub Amp: eD NiNe.1
    Comps: Looking towards ID CTX65cs
    Comp Amp: Needed! Got 150w x2 @ 4 ohms to sell ?
