spl4life Posted May 22, 2010 Report Posted May 22, 2010 (edited) Read... seriously... the first post will explain everything... read it a few times over... fs of the woofer is 38hz... 1130/38 = 29.736 /4 = 7.434 * 12 = 89.21 inches... thats how long the port has to be... sd = .022 m = 34.1000682 inches sq... 34 sq inches of port 89.21 inches long... took me less then 5 mins to calculate... the trickest part is to make the port exactly 89.2 inch long... easiest way to build a tline is with a pvc pipe... get one 8in in diameter, make it 89.21 inches long... mount it on one end.. edit: you dont have to be too exact... round to the nearest quarter inch Edited May 22, 2010 by spl4life Quote My first truck...

dsawyer09 Posted May 22, 2010 Author Report Posted May 22, 2010 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 Quote
