SA-8 35 Hz tuning question


Recommended Posts

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?

How about 18" of 4" aero port with on 1.5 cubes.

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

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.

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

2.19 gross. The displacement of the port should bring it to the recommended 1.5 net right?

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
