    here's an article about "acoustuffing":

    any idea on the effects on different wattages? how many watts are you at, what size speaker?

    the general rule is to use 1 to 1.5 pounds per cubic foot of enclosure volume.

    i always thought pillow stuffing would be a cheaper alternative. you should see the prices some audio places charge for "blu-tak" which you can often get at dollar stores.

    i would have thought that "acousta-stuffing" would raise the Q of a speaker by limiting internal volume, but apparently, it has the opposite effect (provided you don't overstuff... it seems that 1 pound per cubic foot is better than 1.5 from what i've read) by making smaller (sealed especially) boxes "look" larger to your woofer by dampening back waves and lowering your f3 point.

    i've ordered a JBL GT5-15 for use in a 1.9 cubic foot box which actually is just short of the 2 cubic foot maximum recommended by JBL, but running the numbers, that produces a QTC of 1.15 where .707 is actually ideal. then when i ran the numbers for that QTC, i got an internal volume of 42 cubic feet! (about 4 feet by 4 feet square). on a graph, the bass definitely went deeper, but good luck buying an enclosure that big pre-fabbed.

    i'm going to try getting a couple pounds of pillow stuffing INSTEAD of using "egg crate" mattress liner as a poor man's acoustic foam to line the box with. pillow stuffing should not only be cheaper, but actually DEEPEN the bass and probably tame standing waves even better than mattress foam too and MAYBE even tighten the bass up by shrinking the air spring.

    so far, everything i'm reading says this is the way to go with a sealed box with a QTC over 1.0. thanks for verifying that acoustuff etc. is really rebranded pillow/teddybear stuffing.

    Please does the size of sub-woofer box makes the difference of the production?
    And can i build two sub-woofer speaker in one box

    How to make a 6inch woofer box and box size

    AARCHBOLD asks
    I think my subwoofer`s skeakers are too small. Can I just change them for two bigger ones without damaging the subwoofer ? What detail should I take into account before doing it ?

    thank you.. this will help me alot.. including the comments..

    why do you say "without buying polyfill"
    pillow stuffing is polyfill

    No it acts like a buffer... it does the same but for the fraction of the price

    No, it is the same stuff, just not at the inflated markups that audio shops charge. I found it cheaper to actually buy pre-stuffed pillows and gut them when they were on sale then even getting the pillow stuffing on its own.
