hey everyone, i dont; know what polly fill is...or if that is even what you call it...the stuff you put in sub boxes...if anyone can tell me what is it...what is does ...and where i can get it...that would be awesome....the kicker manual recomends filling the sealed box 50% with this stuff

 

Pollyfill is fiberglass insulation....

Anything that makes a good insulator will work... the idea is to absorb accoustic energy and transform it into heat...

It is best used for attenuating distortion when using drivers that have a flexable cone... It will also make the box seem slighly larger to the woofer...

It won't make much if any difference in most subwoofer systems IMO...

 

ok then ...i am gonna tell you my application and you tell me if ineed it or not...i am puting 3 kicker 8" L7's into a sealed truck box with one shared chamber each one will have about .5 ft^3 ....so would i need pollyfill or not...

 

ok cool...thats all i need to know ...thank you = )

 

Pollyfill is fiberglass insulation.... NO IT'S NOT but fiberglass insulation does work for this stuff .Pollyfill is pillow fill or what sleeping bags are filled with

 

^ Ive got a bag of pink insulation that says 'poly fill' on the side [img]graemlins/dunno.gif[/img]

 

Go to sounddomain.com ; In the Subwoofer Solutions category, there's a FAQ and Q&A tutorial sticky by Grand Masta that goes over exactly what you're inquiring about (possibly more). Hope this helps. Cheers.

 

Good tip!

Here's a direct link to the FAQ mentioned by timmyturtle:

There are three types of stuffing that are commonly used for this purpose: fiberglass
insulation, long-fiber wool, and polyester fiberfill. Fiberfill is the best choice because it doesn't come loose and fly around and irritate your skin or lungs like fiberglass, it works as well as either of the others, it's a lot cheaper than wool, and moths hate it. I recently bought five 20-ounce bags of it at $1.99 a pop (a total of 6.26 pounds for $9.95) at
Minnesota Fabrics; that turns out to be about $1.60 a pound. You should be able to find
some at any fabric store or in the bedding section at friendly stores like K-Mart or Home
Depot. http://forum.sounddomain.com/forum/u...&f=11&t=076651
that is what sounddomain said
and
