Does this look right?

I will be purchasing 2 RE SE12's and they will be getting 750 watts RMS each from a BX1500d amp. I am going to go ahead and start my box. I downloaded WinISD and I was playing around a little bit and this is what I came up with:

Volume:3.559 ft^3

Tuning: 32 hz

Outer Dimensions

Width: 36 in

Height: 15 in

Depth: 14.85

2 Vents

Diam: 4.02

Vent Mach: 0.08

Are those some good dimensions for making my SE's sound their best?

Will changing the tuning to say 28 hz make my subs have punchier bass? Someone please clear me up on this.

by "punchier" you mean what

quicker to respond? no

louder? tuning that low is more for sq than loudness

What tuning would be best for 60/40 SPL/SQ?

What equation do you use for finding the port dimensions?

Pay JMAC 8 bucks to make u a great box design.... that guy is great

I am trying to use the equation for the ports. How do I find Av(cross-sectional area of port)?

The 3.6 ft^3, does that include how much area the ports take up? Would it be better if I added the port area to the 3.6 and made a bigger box?
