Poly Fill For Stock Sub????

[Twinturbostroker]

I use to have a Ford Raptor back when they first came out, got over it pretty quick, and put my happy ass back into Powerstroke, but I still check in to see whats going on Raptor forums from time to time. Anyway came across a guy claiming to "get more" out of his factory sub by stuffing it with poly fill, same stuff you'd find in stuffed animals.......any else try this???

Like this.....

JL has been doing that for years in some of their smaller wedge boxes. Not sure just how much of a difference it makes though...

Maye Josh or Rico will comment

Apparently a bag from Hobby Lobby of this stuff is only 2 or 3 bucks, might be worth at least seeing if it makes any difference

The purpose is to reduce sound from bouncing around inside the cabinet, which in turn makes the woofer think the box is larger.

It can also be used to manipulate the harmonics and achieving harder hitting, lower frequency bass notes.

Speaker MFG's have been doing it for years in most every enclosure made.

Walmart sells it by the bag, start with a lot, stuffed full and remove until it sounds just like you want it.

Thank man, I'll give her a whirl tonight.......

does this only apply to sealed enclosures?

^^^ Yup! What the fill does is slow down the sound waves inside the box making them take longer to reflect off the walls (same as a larger box would.) With everything there is always a downside, stuff a box with too much and you will run into heat issues. Just don't try and pack the stuff in, you want it basically how it feels in the bag or in a stuffed animal if not a bit less. Totally an experimentation to get the right amount in the box for the right performance.

It can be used on ported boxes, but you want to make sure the speaker doesn't start blowing it out the port. Its not nearly as common in ported enclosures since they are already relatively large compared to sealed (usually the user has more space to spare in their vehicle for the box) also you aren't going to make huge gains like 1-2+ cubic feet of equivalent internal volume but more like 0-1 ft^3 of equivalent space.

Well, did ya try it!? How'd it work?
