I built a crx style box for 2 15' bls..Box is 7^3 @ 29hz...I personally don't like the way it sounds and want to raise the tuning to about 35hz...How do I go about doing this?

Add panels inside the box to make the internal volume smaller.

i usually use some wide cut 45's in the corners to drop volume and get rid of the 90's

i know that will slow the air movement down to make the box seem bigger not sure how much. recomended 1 bag of polyfill for 1 cu/ft. not sure bout tunage abllity of it. works great in small space enclosure.

the best wa is to shrink the internal volume with some MDF
pannels or fill the corners with 45* like mentioned above
