Posted August 20, 201015 yr ive been told that puttin carpet on the inside of a box will make the sub think the box is bigger there for sound better or louder. but i personaly like fiberglassing the inside to gurantee its super sealed and not falling apart ported or selad enclosure which would be the better idea or maybe carpet over fiberglass
August 20, 201015 yr Not carpet, polyfill.Polyfill and fiberglass do two completely different things to the enclosure, what is your goal?
August 20, 201015 yr Author well i like my system to sound really solid and i also use my daily setup for occasional comps. i would like to know best spl answer though re mx 18 in 6 to 8 cubes ported after displacment
August 20, 201015 yr If your in for SPL you chose the wrong woofer, the MX was not made for it. You can do both, putting resin inside the enclosure will decrease air resistance and seal the enclosure, polyfill will make the woofer "think" it's in a larger enclosure than it's in, it will play a bit deeper than it normally would.

It'll only make the enclosure slightly, you will need 1 Lb of Polyfill per Ft^3. You won't get much back.
