SICKSPD Posted December 17, 2013 Report Share Posted December 17, 2013 Im building a box for 2 SA-8 v2s to 2.19 cubic feet. I want it tuned to 35 hz. How should I build the port? I was thinking 2.5" wide and 10.5 tall. Might this be too big? Id have to make it 24.25" long to tune to 35 hz with it 2.5" wide. But since the port will be in the middle when it splits in opposite directions it will have to be 1.25" wide which seems really narrow. What are your thoughts? should it be wider?

ToNasty Posted December 17, 2013 Report Share Posted December 17, 2013 Well for 1 thing is that net or gross volume? If it's net then 2.19 is way to big for those subs Quote ***Super Sellers List***http://www.stevemeadedesigns.com/board/topic/25829-super-sellers-buyers Link to comment Share on other sites More sharing options...

ToNasty Posted December 17, 2013 Report Share Posted December 17, 2013 Ct sounds 1400.1. No matter what power. For the pair I would do 1.5 cubes net with 28" of port Quote ***Super Sellers List***http://www.stevemeadedesigns.com/board/topic/25829-super-sellers-buyers Link to comment Share on other sites More sharing options...

ToNasty Posted December 17, 2013 Report Share Posted December 17, 2013 I've had plenty I experience with the sa8. A 4" port is enough for 1 8. So if you want to use an aero then I suggest using a 6" for the pair but it will be very long. The lease I would go is 24" of port. I prefer 14" pet sub Quote ***Super Sellers List***http://www.stevemeadedesigns.com/board/topic/25829-super-sellers-buyers Link to comment Share on other sites More sharing options...
Blue Posted December 17, 2013 Report Share Posted December 17, 2013 I litterally just built a box for 2 sa v2 8s today for my jetta. The box is 40 wide, 10 tall and 12 wide. Port is 2x8.5 and is 22 inches long. I will be putting a saz1200 on it in the next few days. They are currently on a the 2 rear channels of a 100.4 and are getting down on low power. Quote formerly known as Blue86f150 its a 4th order just because its tuned in the 40z doesnt mean it wont reach down and jiggle your balls at sub 30 hz frequencies. Regardless if they were dipped platinum and were stuffed in Beyonce's twat.....way too fucking exspensive this sux camel dicks Link to comment Share on other sites More sharing options...
SICKSPD Posted December 17, 2013 Author Report Share Posted December 17, 2013 2.19 gross. The displacement of the port should bring it to the recommended 1.5 net right?

SICKSPD Posted December 17, 2013 Author Report Share Posted December 17, 2013 ok well maybe 2.19 is a tad high for gross. but I'm assuming the gross should be somewhere around 1.9 to 2 cubic feet so with the port taken into account the net volume will be around 1.5-1.6 cubic feet which is where it needs to be. the question is with it being tuned to 35 hz is 2.5 wide by 10.5 tall an okay size port? I just feel like when the port splits into two opposite sides that a port only 1.25" wide seems small Quote 09 Challenger R/T (Audio system under construction): Pioneer AVH-X4500BT (PAC RP4CH11 harness) (2) Sundown Audio SA-8v2 (inverted) CT Sounds AT1400.1D XS Power D3400 40 sq ft.
