Hello,

I need help on a box for a single 15" XXX, ported @ 35 Hz.

These are the measurements inside the car:

I want a single angle btw.

16.5" H
40" W
9" top D
14" bottom D

Thanks all.

Still confused.

I put my numbers in (box too small, will have to go with square) and the port numbers that come out are insanely small.

16H
40W
15D
Wood thickness 1"
Speaker displacement .21
Port freq 35 Hz
Port diameter 3"
1 port
1:.5 slot port

Gross box volume 3.79 cubed
Net box volume 3.78 cubed
Port length 1.86"
Port area 7" squared
Port H 3.76"
Port W 1.88"

Cant be right. The specs RE has for the XXX12 has a 12x8x35 slot port. What am I doing wrong here?

Building a slot ported angled box takes a lot of extreme calculations. So a round port would be your best bet unless you want to find someone with the time and knowledge, like loneranger, but he's gonna charge you a decent amount to design them for you.

nosa - dropping the whole angle-port idea. Just want a regular box with a slot port.
