polyfill?

[AllDayMJ 10+ year member]

alright so right now i have 2 Digital Designs 512 subs in a 4.1cube net box ported to about 42hz. would it do me a lot of good to stuff the enclosure with polyfill so the subs would see more net box volume?

id like to try it out, but my subs are currently in my room thanks to college. when i do it i think i will use a few bags worth and see what happens..

thanks

I never used regular poly fill in a ported box only sealed. I have used batting in horn loaded when the design calls for it. I have seen it used when the port is directly behind the woofer and I dont know what it did but it sounded better. (maybe just less port noise?) was long ago
