Some help for a SPL box ? :D

[orange_soul 0]

I was designing a SPL box for 2 10's but i was seeing in other box's a triangle down in the port here is a image of my design.

is this correcto or do not is very efective in spl designs?

is for 2 10" it have 2.33ft3 with the woofer, port & 45's displacement, the triangle is not contemplated in the displacement.

i hope you can help me

the triangle is to help direct air flow out of the box so i would put it in there

I think thats a pretty common item placed into boxes SPL or not. The 45'd corners generally help with the air flow. Only thing to remember now is that you have a bit more wood in there when you calculate the total volume with displacement

i think it is, here in mexico the model is chevy this is an image

is the same as the opel i think so.

actually the box is all redy made, i put in 2 10" kicker cvr dvc 4ohms and a memphis mojo 2kw old school att 1 ohm , my wiring is 4 lines of 0 Gauge 2+ , 2-

i make 144.1db with the oem battery.

the subs do not support that power is to much in the 8 burp smelle like hot cake

i will put a pair of RE SX DVC of 2ohms to put the mojo at .5ohms and a hc2000 of kinetik or a nsb75 by northstar

i will test any way

thanks for the advice.

I have seen good results in similar cars with the subs and port firing up.

A friend of mine has the same car (2 door version) but we didn't have time to play around with box positioning

use duct tape!

If you have a meter available to you, do a ton of testing with position of things. I'm talking try it with the back seats down, visors down, glove box open, front seats forward/backward more, leaning towards the center of the car, etc. I've seen an extensive test like this done and it gained 2 db just from these little things. and yes, duct tape was actually one of the little tests! I think he applied it around the subs, sort of like an extra sealant between the subs and the box.

^^^^^ X2 on my van i gained by opening the glove box, pressing againts the window where the meter is, lifting the wippers(or however its written lol), pressing aginst the back door and making like a front to back on it..try anything that comes to ur mind

[orange_soul 0]

[danracer 0]
