Hey Guys,

Could anyone help me with a box design, I built some sealed ones, but I just am not sure how to calculate the ports and tuning with ported ones. Even with the Box calculator's. I am looking for a box to hold 2 15 BL's and a box for 1 15 BL. Tuned from 28-32 Hz, Not sure on what would sound better.

30"depth 42"width 20" heigth these are the specs I wanna work with, I can fit more but, this is really what I wanna stay around

Anyway, Thankx to anyone that can help me with this.

Josh

You can do 20H x 20W x 28.5D for a single sub. 3/4" wood except the baffle - double it so it is 1.5" thick. Build the port on one side of the 20 x 20 face - it will be 18.5" x 3". For the port wall, it will extend all the way into the box so that is it 3" from the rear wall, leaving an 18.5" x 3" opening inside the box.

For (2) subs, you can build a second box like the single box (since it will fit), or make a 20H x 39W x 28.5D with an 18.5" x 6" port in the midde of the 39 x 20 face. Same thing for the depth - run it inito the box so it is 3" from the rear wall. This will give you an 18.5" x 3" opening into each chamber of the box.
