Well I was looking around for boxes and came across this one.
All the stats on the box will fit my subs perfectly. I will let you guys know what its quality is and how much room loss I get from it.
He also has another slightly smaller box for sale as well, its base is 8" instead of 10", and its 0.5 cu. ft. per sub instead of 0.75 cu.ft. per sub like the one I just got. It ended up being about $87 after shipping.
