Alright, I have a question for you folk =). Anyways I built a box a few months ago, its a ported 2 cubic foot box. The problem is that i didn't research too much about box making and heres the question, i ported the box through the back, see drawing here

Anyways, i've heard from some places on the net that it doesn't matter which plane you port from as long as it meets certain distance requiremnts from adjacent walls, from other places, i've heard that the box should always be ported on the same plane as the sub itself. I want to know which is true?

I'm asking this because I feel that my box is not performing as well as it could ( i could have also ported it incorrectly, so i'd never know). So im wondering if I should plug up the port and turn my ported box into a sealed one.

 

i did the same thing. figured it would be best for air-flow into the cabin (i have fold-down rear seats) but i found my sub wasnt sounding quite as good as it could be.. i.e i found it just didn't sound "right". i asked about it on here, and it seems it has something to do with the waves... the waves that come from the cone of the sub and the waves that come out of the port? either they cancel each other, or just are heard at different times but either way it didn't sound right the way i had it ported.

anyway, i've been informed it would be in my best interest to fix my box to port it out the front. i am currently still in the design stage of my slot-port firing from the face of the enclosure, to help fix the problem.

 

your best bet is probly to keep the sub and port on the same face if this is going to be stitting in your trunk

 

What make/model subwoofer is it, what are the outer dimensions of the box, and what diameter and length is the port?

 

If the port is less then 1/4 the distance of wavelength your are tuned to from the subwoofer... then it won't matter...

 

hi guys, here's my problem, i can't port from the front because theres absolutely no space to do so, thats why i did it through the back =(. The dimensions of the box are 24" x 14 3/8" x 14", the front face being (14" x 14 3/8"). Also, i could not possible mount the subs/ports on any other side of the box, because the dimension above is only from half of the box, its actually a dual-chambered box. The subs im using are kicker compvr's. the dimension of the port is 4" x 12.someting inches, i can't rmember exactly rigjht now.

 

oh yeah...its sposed to be tuned to something like 33hz....

 

make a new box? 14*18*19 or soemthing.a slot port might be a good sloution for you. what sub are you running?
