[QUOTE="Doxquzme, post: 8854340, member: 689267"] Taking the box dimensions you provided and assuming it is all .75” MDF, that box will have a gross internal volume of almost 1.13 cu. ft. which is much too large for sealed and slightly too small to vent. Time to rethink the subwoofer configuration - In most instances, you can vary the size of the enclosure by roughly 10% without a lot of difference, but if your guess on the box size is correct, you are off by more like 40%. You may want to scrap the single 8” and go with a lower profile box and different sub.
