I got a 12" Cerwin Vega Stroker in a 4cube box made by Obcon. There are 2 4" flared ports on the front. Its got a slot design on one side and just ported on the other. How do I know what the box is tuned to. And is this box to big, some really low notes sound like its farting.

If im correct your box is tuned darn high .. Right around 48-50 hz. May be/ is why it sounds like **** on the low end . Playing to far below the boxes tuning freq. EDIT : did you measure the inside of outside diameter of the port ?

my avatar is the pic of the stroker in that box. dont get me rong it does hit really hard, I took out my rearveiw 3 times but I still want it louder and lower. How do I go about doing that. Make the ports longer or what??????????

pr-festiva
12-22-2008, 04:22 PM
yep ,but the extra port length will take up a little box volume also.

Bass Addict
12-22-2008, 04:25 PM
u need smaller ports so the sub has some resistance on the low notes.the ports are too big.if it was me,i would take the the vent inside the box out,then make the two front ports long,barely coming off the back of the box and go from there.

Actually I think the vegas like 40 Hz tuning

pr-festiva
12-22-2008, 04:29 PM
his problem is he is tuned to high. not the amount of port area just the port length

Bass Addict
12-22-2008, 04:29 PM
maybe,but his box is farting.so something needs to be changed

pr-festiva
12-22-2008, 04:34 PM
im guessing he is driving his sub below tuning, the easy fix would be to make the ports longer.How ever neither of us are standing at his car right now so there might be multiple problems:)

aftershockdb
12-22-2008, 04:34 PM
what if I just plugged 1 of the ports??? There is no vent anywhere, its just 2 ports. the left side inside the box is set up like a slot but it comes out to the port.

pr-festiva
12-22-2008, 04:37 PM
that is a odd way to port a box,,try plugging the left port,,how ever thats not enough port area for clean output

I had 2 12" strokers in roughly 3.25 cubes each tuned to about 36 with a slot port and was overly satisfied!

12-22-2008, 04:41 PM

hope you dont mind a million ?'s, I appreciate the help, Im somewhat new to this. Would I be better off going with a big sealed box or ported. The sound Im lookin for is as loud as possible, low, and hard hittin. Something compatible for everyday driver but yet ready for comp.

pr-festiva
12-22-2008, 09:43 PM
