Im a noob when it comes to sub enclosures... and I need help.

The width of the box should be around 36"

Height= no more than 18"

I would like to make round ports but I was told not to...heres a sketch a guy made for me. The box is tuned to 32hz. The 3 round ports are 6inch by 16.75L.

So I guess Im most likely going with the slot port design. This is what some guy told me, not sure if he was right:

build the box with the dimensions you have:

36 (L) x 28 (W) x 18 (H)

slot port:

5.5 (W) x 16.5 (H) x 42.75 (L)

Ends up being:

6.1ft^3 @ 28.05Hz
