Wassalla Posted December 9, 2011 Report Posted December 9, 2011 Im building a new box for my dc level 3 15 just because i want something a little cleaner and better looking. The old box was around 3.2 cubic feet tuned to 34hz with a 4inch aero port. Now with my new design i can play anywhere between 3-5 cubic feet. But im just looking for suggestions, like port length, tuning, and dimensions. Also what position the port should face, however im dealing with an extended cab nissan frontier 2003, and can only do to the right side or front towards the driver seat. Thanks Quote
CJ18 Posted December 9, 2011 Report Posted December 9, 2011 The only problem with your old box was you were choking it with that tiny ass port. Just go with a slot port with 15in2 per ft3. I would build it at 3.5ft3 after displacements. Quote
Wassalla Posted December 9, 2011 Author Report Posted December 9, 2011 Okay thanks, thats what i was thinking. Now with tuning a square port, how do you actually accomplish that? like with lengths of internal baffles? Quote
CJ18 Posted December 9, 2011 Report Posted December 9, 2011 go to the subwoofer section and download the torres box calculator. Quote
Wassalla Posted December 9, 2011 Author Report Posted December 9, 2011 Okay so i got that, but my box is and extremely odd shape due to size restrictions. but where i want my port to exit, it will be 14.5in(inner measurement) but when i put that in the calculator it says i need like .25in tall port??? not sure i understand correctly or im doing something wrong?

fmedina Posted December 9, 2011 Report Posted December 9, 2011 If you need some help on a design shoot me a pm man. I'd be more that glad to help. Quote
matt402 Posted December 9, 2011 Report Posted December 9, 2011 (edited) the port area (opening) should be 50-60 square inches. the port will need to be longer than ur box is deep so its going to be an L shape... Edited December 9, 2011 by matt402 Quote
