Jake Pichola Posted May 20, 2015 Report Share Posted May 20, 2015 im wondering if polyfill would actually make a difference on an sa 15 in a ported 3 cu box. ive heard that it makes lows hit better but idk how a bunch of cotton would hold up inside a box with an sa15. wouldnt it get sucked in around the spiders and maybe even in where the coils are and cause it to overhear? any input would be great Link to comment Share on other sites More sharing options...
RooTxBeeR Posted May 20, 2015 Report Share Posted May 20, 2015 Only effects sealed enclosures. Go ahead and throw some ported box and upload the video so we can have some luls. But for real, sealed only.

Ahmed Johnson Posted May 20, 2015 Report Share Posted May 20, 2015 I've tried it in a ported box and it seemed like I lost pressure. Link to comment Share on other sites More sharing options...

But for real, sealed only. Not true. It can have a profound effect on vented enclosures as well. You just have to chicken wire the throat of the port or a similar method of keeping the shit in there. Because I can tell you from experience that it comes out IN A HURRY. Lol Link to comment Share on other sites More sharing options...
Triticum Agricolam Posted June 7, 2015 Report Share Posted June 7, 2015 As other have said, polyfill (it's not cotton, don't use cotton) will only hurt your output with a ported box.

Skullz Posted June 7, 2015 Report Share Posted June 7, 2015 Use a poly batting instead of polyfill to achieve the same performance without the effects of tricking the sub acting as if it is in a larger enclosure. They come in a 1" thickness and line 3 walls with it, it will make the enclosure have a deeper richer sound to it. http://www.ebay.com/itm/Bonded-Dacron-Upholstery-Grade-Polyester-Batting-48-Inch-Wide-Sold-By-The-Yard-/151702528895?pt=LH_DefaultDomain_0&hash=item23522ce37f 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...

As Skullz said, you'd want to use the actual batting vs the loose stuff. It can DEFINITELY affect and improve the sound of some ported enclosures for sure. Most here have never tried it and don't have experience other than sealed applications. To get the batting to stick, you can glue and staple of you'd like. Im not the one you want to try to troll. Just a fyi for you. Link to comment Share on other sites More sharing options...
Yomalley Posted January 25, 2016 Report Share Posted January 25, 2016 Have a GMC crew cab with 2 12" kicker CompRTs in a down fire box. I spoke with a Kicker rep because I've read that the 500 RMS rating is under rated by the company and more like around 700. He also suggested to polyfill about half the box which is .87 cu ft. I've been reading that people just stuff it into the box, but I feel that would turn out not so well with my subs facing down. I've seen on YouTube about using spray adhesive to line the walls but wondering if layering sheets of this stuff with minimal glue is a feasable option. Any help/tip. Thinking about also ditching kickers for some RE SCX 12's. Link to comment Share on other sites More sharing options...
Skullz Posted January 26, 2016 Report Share Posted January 26, 2016 Providing the box is sealed you'll be fine just placing it in the box, and the subs bottom will keep the polyfill from coming up into the sub. 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...
