I built a 2 12box and I only cut 1 hole for speaker right now.My question is there something you can put into the box through the 1 12 hole to make the box smaller?Like a pillow or foam or something like that.I really would hate to cut the box again.the box is h 14 3\4,w 18,L 32 any ideas?

 

what now?

let me get this straight... you built a box for 2 12s but only runnen one 12 right now.......

if so cut cut the box apart and screw a new wall on it to box it off...
thats why most people for a sealed box build in a seperator panel in the middle to seal the subs off from eachother.

if you realy like the box then just build another one for just that one sub. or just go buy a box for it if its a cheap sub...... a prefab box from walmart will do.LOL
