Don't forget to deduct the volume of airspace your subwoofer will consume to your box volume calculations.
For anyone interested, there are 120 cups of liquid in a cubic foot of space.
to figure the volume your subwoofer will take up, fill a 5 gallon bucket to the very top. Take your subwoofer, and loosely place it in a small trash bag, leaving a little slack around the basket. Lower the sub into the bucket up to the mounting ring, and it will displace some of the water from the bucket.
Now you need to refill the bucket, and count the # of cups it takes to get back to full.
Now do the math. Example. 8 cups to refill bucket..... 8 divided by 120 is .06 Your sub takes up .06 cu ft of Airspace.
Or do like the rest of us do, and take a wild guess!
Commonplace in a subwoofer enclosure is + or - 10% with no effect on performance.
