my last box I put some big cotton things in there I dont rememebr what they are called. Its made of cotton and they arent the little cotton balls. If you go to walmart or elsewhere that sells fabrics youll find something useful to put in there.

yea thats it. Thats good stuff to put in. doesnt move or rattle. it stays put and works like a charm and very lightweight.

if you use polyfil you can make the box smaller. it will "trick" the sub into thinking that the box is bigger than it actually is

what would look good is to have slotted ports on the same plane of the subs. have 2 slotted ports, tuned. and still have polyfill in your enclouser. to properly use polyfill. apply it to all sides of the box inside, you ussually supposed to fill 75% of the box to get the right effect. possibly not even that much cause your using slotted ports in your enclouser, polyfil is more useful for sealed boxes, but still can be used in a ported. let us know how it goes. and post pics too!

i was under the impression that polyfill in ported boxes are useless. thats why i haven't stuffed my clearwater design box but if anyone can prove me wrong I have 5pounds still left I am stuffing ASAP. but polyfill in sealed boxes are great
