If you can, you might want a little more port area, its ok now, but to be safe you might want to go with a 3" port. But looks good other than that.

I get you at 2.1 cuft tuned to 34.6 hertz after all displacements. Your port area will be fine, as it is basically 16 square inches per cubic foot. More importantly at 600 watts the most your vent velocity reaches is 13.5 m/s and is clearly under 5% mach.

On a side note I know of people having good success with the hype-argh twelves at 2.4 cuft tuned to 34 hertz. If you need help with the design feel free to PM me.
