i know you already posted some specs but after reading that thread a few times i got these as my numbers:
7.43 ft (same as what you got)
but when i measured the cone to get the surface area, i got 7.25 from middle of surround to the middle of surround. and if i do the same math as he did then it should be 7.25/2 then 3.63*3.63*3.14 = 41.38 which would round down to 40sq in
am i right so far?
but the main thing im lost on is how to design this, its gonna be for my truck btw, so i was gonna do mdf not pvc pipe.
incase someone wants to help my MAX dimensions are:
Width: 53"
Length: 34"
Height: 21"
but i would prefer the width to be either at or under 35" cuz i still wanmna use my back seat
i was gonna ask a buddy of mine about helping me design today, but idk how much he knows about T-Lines, so again any help is appreciated
