If you're set on using a bandpass box, then this might work for EACH driver: sealed volume = 1.5 cu.ft. vented volume = 1.23 cu.ft. Fb = 54 Hz (two 3" ports, 8.5" long). This is assuming of course that the parameters you gave are correct. I wouldn't use all three drivers in one box. You'll end up with one bigass box that you'll need two or three people to help you move - and tuning it will be somewhat "difficult". An alternative is a simple EBS alignment: 3.25 cu.ft. per driver tuned to 22.5 Hz (1 3" port 9.25" long). If it doesn't sound loud enough for you, decrease the length of the port, or try TWO 3" ports, each 10.75" long. Brian |
