Hey, i finished my box for my BPD 1803.. After I subtract all the bracing/driver/etc i have a net enclosure of 11.302 ft3. I want to tune it to 17.5hz and the inside diameter of the sonotube port I will be using is 8.25". I come up with a port 35" long, does that look about right? How do you account for the volume the port itself takes up?
Hopefully the airspeed won't be too high and the enclosure isn't under-ported, it would have been too difficult to fit a 10" port in.
