Subwoofer Box Filling

[Hanso]

I'm making a sealed sub box for my Stagea & have a couple of questions.

1. What is the stuff you put inside a sub box called? It is white in the sub box I have atm.

2. Where can I buy it from?

Cheers,

Adam

I think its called polyfill. Pretty much pillow stuffing. some boxes use fiberglass insulation material but alot of people dont think fiberglass is very safe.

Not sure where you can buy it though

Cheers mate, I'll have a look at Jaycar over the weekend to see if they stock it.

Its called Dacron, buy it from spot light in loose and sheet form.

spotlight sells it for less then 8 bucks

its used for pillow stuffing, polyfill, but buy loose stuff not sheets of it unless using in a ported box. spray glue the box walls , and lightly take hand fulls of it and stick it to the box /glue

do not get too much in it or it will sound muffled or flat. and do not get any on the sub frame or ports for those of using it in ported boxes

a light fill is all you need, to smooth out the sound from a boomy sounding box, bass can sound tighter/quicker

polyfill tricks the box into thinking its bigger then it is, by bending sound waves around the fibre's the sound length changes(acoustical physics, simplified)

Yeah I use poliester fiberfill for all my boxs, just keep it away from the ports and you will be fine. bit of hot glue or stables to put it in.

You can get it just about any fabric store, Ive been meaning to try the wool fiberfill oneday.

wool doesnt sound good, the weave is too tight, they used it on some home speakers back in the day as a gimick

hot glue falls off if applied in a dusty box or vibration

staples can rust, and vibrate out, or even create a sound of there own , like a tuning fork? stick with spray glue or contact cement

Guess I wont try it then, never had any rust or fall off, as I use stainless staples from a compressed gun. contact cement does work good!, some people cant stand the smell so I suggested hot glue as an alternative, provided the surface is clean it shouldnt be a problem.

Cheers for all your help. Looks like I'm off to Spotlight later today (never thought I'd say that lol)
