Longer the port a little. Also note that calc doesn't take into driver displacement (.19cf i think) which wil throw **** off a little.

No box is good enough for a Q IMO :P

which box? the second one, after driver displacement would be around 3.9 cubes tuned to around 29...at least that what I'd think. Why would he want a longer port?

whats that mean

well I tried using the subwoofer tools box caculator or whatever but I put in the length to be 26" and it keeps automatically puttin it back to 31.5". If anyone could help me out with that, I have L-26" x W-32" x H-14" tuned between 28-33Hz. It could probably go an inch wider but I made it that size to be able to get it in the trunk.

Sorry if I'm a noob but where is the link to that box calculator thingy?

I meant shorten it. No real need to have it tuned that low..

Forget the online calcs and have someone do it for you that KNOWS what they're doing :)

I was going to post this in your forum, but got carried away so I thought I would start my own.

read thru it and see if you get what I'm trying to say.
