    Ive been reading on audio review that people have been stuffing the inside of the box with pillow case stuffing. I was wondering if anyone could tell me the best kind to use and how to properly do it.

    Pop off the speaker grill and take the speaker driver out of the front of the cabinet (8 screws). Disconnect the wires from the driver and set it aside. Get some polyfill batting. I use the 1 ½ inch sheet type. Cut one piece to cover the side, across the back and up the other side. Cut another to cover the bottom across the back and across the top. Attach with hot glue to inside of cabinet. Reattach the driver wires and reassemble.

    Alex, try any fabric store, look in the yellow pages for a store near you. Good luck! [​IMG] BTW, the polyfill is very cheap, it'll cost you about $1.50 plus the price of glue.

    The stuff at walmart was 5 for a roll about 2 feet long. It didnt seem that great of a deal to me.

    Does this apply to crappy speakers too? I am really interested in the whole DIY thing and am starting off by playing w/ a shoddy 10 yr old sony bookshelf. If I opened it and lined it w/ polyfill would that tighten the bass? Would it have some cons in sound quality say in the higher frequencies?

    Me neither. I paid, like $2.50, for a big roll at a Christmas/Craft store that my wife goes to.

    I went to Lowe's or you can go to any large hardware store.

    Go to the area where they sell the ceiling tile and purchase a piece of acoustical tile like they use in suspeneded ceilings. Its just fiberglass that is an 1 1/4 inch thick. It is perfect. I paid $3.88 for one piece and still had enough left to do another. I used spray adhesive to stick it on.

    Better yet, just spend $2.50 for a 24 ounce bag of polyfill from Wal-Mart (used to stuff pillows) and stuff 16 ounces of it in the subwoofer enclosure. You don't even need glue.

    i picked up a roll of polyesterfiberfill from walmart for 3 bucks. Its only a 1/2 thick but I figured that I can double up the sheets. I figured that the sheets would be better because it would be cleaner to install with less mess than bulk fiberfill. Anyone else?

    Patrick?

    Are you saying to just stuff it through the flow port in the back? (I.E. don't have to take the driver out?)

    Also, If you line the inside with filler, should you take care not to block the flow port in the back?

    What kind of inprovement can you expect to see from adding filler to the SAWM40?

    I love it for movies (90-95%) but it is a little boomy for music.

    Thanks!

    Well. I am glad to see this thread.

    Last night I "stuffed" my sony. I used the expensive acousta stuff from parts express (although i would imagine this isnt needed) I used the whole bag (1 pound). Stuffed the bottom, leaving the port open, then the sides, then I sprayed some adhesive directly on the stuffing & stuck it too the top of the cabinet.

    Maybe I am not used to the new sound, but it seems that I LOST bass. I had to turn the sub & the receiver up to get the 'thump' back when playing music. Did I put TOO much stuffing in the cabinet? Or, like I said am I just not used to it?

    Well i went over to lowes and bought one of those acoustical tiles for 4 bucks. They seem pretty nice but im wondering how their performance would rate as opposed to the fiberfill. If anyone knows id really appreciate the input. Thanks.
