Trying to get a general consensus on Poli-fill box stuffing. Good?bad?
Trying to get everything to put a box together for 2 15" solobaric L7's.

 

From what I understand on polyfill poeple do it to "fool" the speaker into thinking it's in a larger box to get a deeper bass sound. So on a 15 I wouldn't bother but then again for the price of a bag of polyfill it's worth testing out.

 

Thats what I thought, I can get a 2 1/2pound bag for $20. Just wanted opinions.

 

According to Polk, you can build the box 10% smaller than spec, using 1 lb. of Dacron per cubic foot of enclosure volume.

 

It's simply a matter of box size.

If you make your box smaller than the volume you'd like... stuff it.

If you have plenty of volume as is... don't waste your money. Stuffing simply aids the 'damping' effect of the box/air. -And it's proven to work to some extent. Remember 10% is a max for an IDEAL condition.

For example, your sub recommends a 1.75cu inch enclosure, and by design/fit you can only tweak out 1.5. You have the "option" to stuff. But depending on your taste - you could also leave it as is.

If your box size is 2.5cu ft, I would NOT stuff, in this situation you would be "overdamped"

Imagine your speaker as the spring in this website... too much or too little bounce is a bad thing
