Also i tried putting in a 5 inch diamiter port into winisd and it says that at 38hz my port would be 17.5 inches long and would be about 2 inches away from the transmission hump wall. But where could i get a 5" port??? i've looked for 5" pvc but it doesn't seem to exist.

I've looked on alot a places online that say its not a good idea to run the sa8's ported and sundown doesn't even have a recommended box for the subwoofer sealed. Also i dont really understand the way flared ports work. When i put my box info into winisd with a 4" port thats 10 inches long, my...

Also is tuning with a flared port different then just tuning for a regular pvc port? if i could just use one 4" port then that would be great

Well i closed the hole already but i dont think i can run the sundown sa8's sealed. The only things i think i can do to save this box would be either a single 6" port thats 17" long but it would be close to where the transmission hump is. It would only be 2 inches away from a wall which is...

Well i tried splitting the box and seeing what would happen if i put a 4 inch port but is says i need a port thats 30" long and i dont have enough space to fit that, thats why i was wanting to try the 2" port but i just calculated and it reduces my port area by alot

so would it be better to divide the box and do the (2) 2" ports on both side?? or can i leave it one chamber and do (2) 3" ports to ones side??

yes i am accounting for port and subwoofer displacement, my box is on the small side but a tech from sundown said is enough air space for the subs since im giving them more power than the recommended rms. I was just trying out different port sizes and i input (2) 2" ports which it calculated...

I have tried running that though winisd and every time i do it gives me a port thats too long, it says that with a 4 inch port is had to be 31" long which i cannot possibly fit, and if i split the box each chamber becomes about .85ft^3

Im trying to redesign the port for my box for 4 sa8's i previously had a 4 inch port, but got too much port noise. I input all my data into winisd and i can run (2) 3 inch port or even (3) 2 inch ports. Is there any downsides to running multiple smaller ports instead of one big port? also this...

i tried to use a single 4 inch port but i got too much port noise, i reran my box through winisd and it says i can use 2 3 inch ports, would that work?

Bump Does anyone know if 3 2" ports will work for the 4 sa8's? Winisd states the port mach will be down to .10

Also i could leave the box as one hole chamber, winisd states i should be able to use 3 2 inch ports that are 9.5 inches long. If i do that the subwoofers would see .45 each after displacements. The only thing im worried about if i do that the ports would be behind one pair of subwoofers, would...

i ran my design through winisd, im trying to make the box i have work. I was thinking of splitting the box into two chambers and porting both sides. Winisd says i can use 2 ports that are 2 inches by 14.5 inches which would leave me with a tuning of 36hz and each woofer would be left with .425...

Before factoring port displacement but after removing subwoofer and bracing displacement i have 1.881 ft^3, if the port area is too small would i get port noise?

Thats the biggest port i could do there was no place for a bigger port
