Subwoofer output help

[Holmz]

I was wondering if anyone would help me out with the design of a slot ported box. I tried to find a program that worked with my MacBook Pro. No luck. Foy my HST-15 the box needs to be 2^2 ft(not including the sub or port) and a 25 Hz tune. I have 16” for width, 20-24” in depth, and the height can be what is needed to get the 2^2 ft + sub(0.55^2 ft) + port. Thank everyone for all the help and advice.

1 cubic foot = 12" x 12" x 12"
so 2 cubic feet = 2x12^3

Required height = 2x12^3 / (16"x20")

^That^ is intèrnal, and one still needs the port.

So...... At lunch I was able to find a few videos about port area calculations. I have a better understanding of how stuff works in subbox pro.
