Kinda bored..figured id share my little box design.
its like 9 cubic ft (4.5 per chamber) tuned to about 30 hz. its 2 layers thick all around, gonna add 45's in it of course. probably fiberglass most of the inside so there are no 90 degree angles.. also planning for threaded rods for extra strength. box is about 60 X 22 X 18..anyone got a ball park on wut i can expect it to weigh? and for that matter how much wood im gonna need... kinda figuring atleast 4 sheets
