I'm trying to figure this out on my own..forgive me for my misunderstandings.
Respectively, these are my dimensions I've come up with..they are loose, I am just trying to match my Qts accurately.
This is a wedge shaped-sealedbox. D2 obviously being the top depth dimension.
These measurements yield 0.58 cu ft .. which I know is a tad large, but I am compensating for some bracing. Probably going to rip the 3/4 MDF down to 1/2"(as I have a lot of stock to waste) and brace all the seams.
Fs: 25 Hz • Magnet weight: 150 oz. • SPL: 86 dB 1W/1m • Vas: 3.00 cu. ft. • Qms: 3.12 • Qes: 0.58 • Qts: 0.49 • Xmax: 14.3 mm • Dimensions: Overall diameter: 12-3/8", Cutout diameter: 11-1/8", Depth: 5-3/8"
