Poly fill yes or no?

[stocker08 10+ year member]

I have a 12" W6 in a sealed box. The cubic feet reccomended is about 1.25 according to JL. Mine has about 1.15. Will adding poly fill help me out too much? Is it worth the hassle?

I think i am going to end up building a ported box for it eventually anyways, I am not to impressed with the amount of output from it right now and i have heard that in the right box, it can be louder and still sound very good.

Cool, thats what I was hoping. I am pretty under impressed with my W6 as of now. Part of that may be the fact that I went the lazy route and put it in a box a little too small.......

How much do you use?

I use like a 1/2 lb per cubic foot of air space. Also i buy it from http://www.parts-express.com/home.cfm?CFID=4419832&CFTOKEN=76001821

I know what poly fill is and why its used but why do you guys use it in all your boxes assuming airspace is correct, is there something i dont know?

i use it in all my ported boxes.i just like the sound better with it in there.maybe its just a mental thing.Ive tried it with and without..i keep it in there.

Yo OP, I would use some poly fill for the box you have since its smaller than JL specs. Don't get it in your head that the w6 bill bump super hard though, jl makes sq subs so if your after spl look into another sub, it will sound good though.

But if you do try the PF let us know what you hear.

I prefer to use the filling from adult diapers.

It's kind of embaressing buying them from the local grocery store.

but the improvement in sound quality is worth it.

If you don't use all of the diapers you can get your girlfriend to wear them and pee in them.. if you're into that sort of thing..

if he adds enough there will be a difference.. jl recommends pretty small boxes so changing the size of the box may allow it to hit different notes.. they only suggest 3 cubes ported for 2 i did 4 and it was great

Oh come on now ... I got a big ol' bag of polyfill at our local JoAnn's Fabrics for 3 bucks. Perfect-o! Tightened up the bass in my sealed box very nicely. It's kinda like cooking ... It's that final touch that makes it go from good to great.
