carshateme Posted February 9, 2012 Author Report Share Posted February 9, 2012 (edited) number of common port walls should be 2. and the box is too small make it taller like the first design, just make the port taller along with the box. i.e. the box is 15" tall, port should be 13.5" tall, 2 common port walls. if you're shooting for 1.5 cubes per sub, the box should be ~3 cubes net Oh I see what you did there. Is the box still too small? Edited February 9, 2012 by carshateme Quote New build coming soon.

Joe X Posted February 9, 2012 Report Share Posted February 9, 2012 You changed the driver displacement to a wrong value it should be 0.2 cubic feet as before. Quote Link to comment Share on other sites More sharing options...
stevog Posted February 9, 2012 Report Share Posted February 9, 2012 port is a little small it should be atleast 12-16 inches per foot Quote Link to comment Share on other sites More sharing options...
carshateme Posted February 9, 2012 Author Report Share Posted February 9, 2012 You changed the driver displacement to a wrong value it should be 0.2 cubic feet as before. The sub displacement is .071 according to http://support.alpine-usa.com/products/documents/OM_SWR-1242D.PDF Quote New build coming soon.

Guest Posted February 9, 2012 Report Share Posted February 9, 2012 needs more port. on the lower-ish right it tells you port area range and right under that port area. if you cant figure out why these two are correlated you should stop trying.
