Box Design

[Untouchable11 10+ year member]

Hey guys, I found my copy of BBP6, and I noticed a few flaws in the design that I had planned. I realize that my trunk is not wide enough for two 15" subs, and a six in port, so I had another idea...

I was thinking of putting the subs at top, and the port at the bottom of the front baffle, like this.. my paint skills ****

The only problem is, BBP6, keeps giving me an outrageous port length, somewhere of 43+ inches.

I was wondering if someone could design me a box like this?

If I had a 33.5" Wide port, by 2.75 inches tall, my calculations say that I should have a port length of about 26.79"?

Could you design a box like that, or is it possible?

My max dimensions are:

Height 18"

Width 35"

Depth 30"

I was thinking of a port face of 33.5" wide, and 2.75" inches tall, and a tuning of 28 Hz.

Thanks,

Ry

It's actually 9:1, not 10:1
