polyfill question!

[stanpho]

My box is 0.895 cu ft.

The sub is rated at 1.0 cu ft.

From what I've read, 1lb of polyfill will "increase" volume by 30%. So I should just add about 1/2lb of polyfill, to reach my desired ~1.0 cu ft?

Thanks

just build a new box that is 1 cu ft

Obviously that would be ideal if possible, but that's not my question.

just stuff it with about 1lb and you'll be fine

I think you may have misread 3% as 30% //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

I didn't even catch that!!! this is true...30% would be one hell of some area to make up with polyfill right?//content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

just stuff 6 pairs of old socks and fabric softner in the box. it will keep the socks clean, make your vehicle smell clean when the bass hits,and give you some high spl.

You will not notice a difference in 0.1 cube. There is little reason to add filler to it.

^ but why not add some filler though ? It will definatly add some apparent volume and the more volume teh better !

(I wouldn't hold my breath on 30% + gains like a nutt tugger magazine writer might claim, tho)

cant the air moving around inside the box blow the polyfill apart and get stuck in the sub n crap??

Keep it clear of the pole vent and you should be fine. Polyfil is long stranded and holds together very well and the pole vent is the only place in a sealed box that air is really moving.

There seems to be a lot of people who dont think its necessary to use polyfill. I dont know for sure how much it affects the box volume or the output, but polyfill has been used for years in most quality home speakers....

I.e. - I dont think it will hurt to use it.

I just built a box for my Arc Audio ARC12 (1.22 ft^3 sealed, with 1 lb. of polyfill) and it sounds fantastic! Now granted, I did not try the box without the poly, but I doubt it would sound any better without the poly.
