Clif Posted November 13, 2008 Report Share Posted November 13, 2008 (edited) So im going to build one just a simple question. When finding the port area (i wanna use 2 tens) do i take the cone area of just one or 2 subs? and for the length will it also be the same for one or 2 subs? Im assuming i would take the cone area of the 2 subs put together and use the fs of the subs for the length. here is what i came up with: 2 10“ subs 78.5 sq in x 2 = 157 sq inchs 200sq inches tapering down to 157 sq inch with the last 20 inches of port all 157sq inches fs is 26.6 x .25= 6.65’ = 79.8” of port Edited November 13, 2008 by Clif Quote 03 Trailblazer EXT LT In Dash Rear Flip Down Polk Audio Font & Rear Stage Hifonics Zeus 4 Chan Amp Hifonics Brutus Mono Amp 12" Rockford Fosgate Power HX2 T-Line tuned to 45hz 18"BTL T-line @31Hz (9 weeks pregnant) Link to comment Share on other sites More sharing options...
