I got an ugly box with the subs I bought recently. it was free.
the box is huge. i measured it to be 32x14.623x22.5. The thickness of the majority of the wood is .8125 but the rear piece is thinner. Using the numbers given and not accounting for the thinner piece, I figured inner cubes to be 4.76953.. (the12volt.com). It has a port and using backwards math, i believe it is tuned to somewhere around 32.65 hertz. I do not know because I do not know how to measure the depth of the port.the inner wall is shorter and the outer wall of the box is longer, but has a wedge like build in the corner. so how do i measure it's depth?
also I think the top of this box "flexs" with the subs. I'm really sure this is bad...anyway to fix this? My subs are monsters with 33mm excursion which is why i think it flexs.
Let me know any tips or if I should just build a new box.
(ideal Treo spec box calls for at least 4.2 cubes and a 40sq in port)
