its poly fil its stuff like cotton that you can just stuff in your box. It makes it sound better and if you have a bigger box it can make it seem like its a smaller box. But then again it cuts down on the spl i believe. Anyone correct me if im wrong.
okay. I have a kicker L7 15" dual 2 in a ported box tuned to 35hz-40hz and 3.5 cubic. It is braced and sealed really good and the dual 2006 l7 is pushed by a kicker 1200/1 amp. I know the sound quality sucks but I want SPL. Should I fill it with poly fill? Also another question I have kappa 3 ways (the newest models) in normal sized 6x9 sealed boxes with bass blockers-(200 watt)that go on the + terminal. Should I put a little poly fill in the box with the Kappa's or does it matter. I have to have them in the box because they will not fit in my truck. Should I leave the bass blockers on because they do block a lot of the bass in the boxes, but I do not know if they affect the wattage. Sorry for all the questions! Thanks
Umm can you actually use it in a ported box? I know if I was to stuff my ported box it would be in my trunk pretty quick, lol. Poly slows the movement of air within the enclosure to make the sub(s) believe it is in a larger one, usually resulting in deeper more accurate bass. Maybe if you glued poly pads to the ported enclosure walls? Polo..
polyfill absorbs standing waves (sealed) / a ported box wont have many standing waves at all.
polyfill works on the pricincples of thermodynamics.
heat builds up in an enclosure due to the mechanical movment of the speaker moving back and forth.
with polyfill the fibers wiggle and move back and forth and help to dissipate some of the heat created. since the heat in now being dissipated the speaker thinks its in a larger enclosure than it is because it can produce more heat.
polyfill can also help to absorb standing waves. standing waves are the result of the rear wave of the speaker, reflecting off the internal walls and then meeting the other reflected waves in the enclosure. standing waves can cause your drivers reponse to sound muddy or inaccurate.
Thanks for the help! Do you think I would be wasting my time to put a little bit in with the kappas 6x9's in there sealed box? I don't want more bass and that is why I bought the bass reducers for the + terminal. Thanks

YES polyifull works wonders for midbass, drivers in their own box... they will improve the SQ of the 6x9s, it will improve the speaker response..
yea Chad polyfill works wonders for small drivers like that in their own enclose/box.. improves sq alot, try it, and see how it sounds... u can always remove it if u dont like it. Post back and tell us...
thats a good question. i am gonna dynamat the door this saturday afternoon. i will post it after i do that. i will first take out the polyfill and deaden the door and see how it sounds. after that i'll put the polyfill back in with the dynamat and see how that sounds. but i do need to dynamat the door cause it rattles at high volume.
