[bad03ranger]

Im going to run DD512s for right now but will be upgrading to the 2512s later on

I have tried to figure this out but im stupid and cannot seem to get winisd figured out!!

Any way how long do my ports need to be i want to be at about 3.5-4cu' NET not sure if it will happen
tuned to 35-45 Hz my port area is 33.75sq" each.

The box can be deeper if it needs to be but no taller or wider

if someone could help me figure this out that would be great

I cant give you a port length for a range of volume.

I can design one for you real quickl if you'd like.

if you could that would be great, i have done everything i can think of but cant get the port length figured out

Is a PWK box worth the $50 design fee?

Im not trying to win any comps with this set up just good SQ for my daily driver 2002 Accord 2Dr

No.

There are plenty of people here who can design you a box for cheap. PWK ported boxes are nothing special. Now, if you were wanting to do something complicated, like a folded horn, then I can understand if you wanted to seek his designs...but normal ported boxes are not worth that kind of money...not even close.

I think the port is supposed to be 13.5" tall, correct?

what about dual slot port?

do i just make them 1.75" wide

the reason for the dual slot is im going to make a front baffle to cover the box and flush mount the sub similar to this but with a mesh cut out for the area in front of the ports

As for dual ports, I wouldnt really bother.
