What if the box is slightly smaller then needed???

[timsm80]

i have a .6 ported box and the sub im looking at requires .75. Will it sound decent???

Grab a bag of 1 pound Polyfill at Walmart for $3 and change. Polyfill will trick the sub into thinking the box is larger than it is. You should only need about 1/2-3/4 of the bag.

Is the .6 cubes ported before or after displacement and port?
