[QUOTE="Jeffdachef, post: 8632644, member: 650438"] only works for sealed, completely useless for ported. Also builds heat faster and does not get dissapted as well, stuffing will fly out of the port over time or the fill will get caught in your voice coil ruining your subwoofer. You never plan any ported subwoofer builds with polyfill in mind, thats a disaster waiting to happen. Forgot to tell you, your port length cant be longer than any of the dimensions. you can do 8x23x23 with a 17 inch long 4 inch port for 34hz 1.45 cubic feet. You can safely do up to half the port diameter to the rear wall for the port to breathe. [/QUOTE]
