hey guys whats up? haven't been on in a while. anyway im looking to upgrade my system and im looking at the havoc for my next sub. i allready have the amp RE12.1 1200wrms+ but im not sure on the box. i allready have a box that my atlas 15 is in but don't know if itll work for the havoc. the box is 3.4cf net tuned to 30hz but heres the problem im only using 2 4inch ports so port area is low. so im wondering will 2 4inch ports be enough? i have no port nosie with the atlas but the havoc is a lot more sub so im not sure? any info would be greatly appriceated! thanls dustin.

3.4cuft is fine for the havoc, what i would do is go ahead and drop it in that same box, if you like it keep it if you dont build a new box

ya im not concerned about the CF just the port area. since im only using 2 4inch ports im worried about port noise.

2 4" ports are fine also

whats the height of your box?

um im not exactly sure but i think its right around 14-15inchs tall, i know it barely fits in my trunk and the sub fires up.

ye man. youll be fine 3.4cuft with 2 4" slot ports @ 30 hz is good

your talking about slot ports right? not aero's?

na areo or more like pvc pipe with a very slight flared edge. i thought using areos you didn't need as much port compared to slot?

Normally, a single dimension of 2", 3", 4", 6", etc. means a round port.

If they are aeros, should be fine. If not, I would cut the holes out larger and replace them with aeros that are 1" longer than the ports you have in there now.

But the best solution is to try it as is right now and go from there. . .
