Could someone just take a look at these dimensions?

Looks like it is tuned to high. After sub displacement I got the enclosure at 2.38ft^3 @ ~36hz.

Where are you getting these numbers from? The sub's displacement is .18 ft^3 which would bring the total to 2.445 ft^3.

I did the math. I wouldn't trust RE's calculator.

I've entered the formulas into a spreadsheet so it is easier and quicker also.
