I'm designing the enclosure for my second diy sub and I'm wondering about enclosure shape. I read about volume and port size/length as the most important aspects of an enclosure but never do I read about shape.
So let's say, at the extreme, that you have a driver with 2" clearance behind the magnet but 3 ft^3 above it. Will that really function the same as a down-firing sub with the same volume directly behind the driver?
My current design for a dual 12" sub requires 7.5 ft^3, tuned to 21.14 Hz with four 5.5" x 6.1' ports; so I thought I'd make it a triangular pillar that fits into a corner (since it's gonna be a beast). I'm wondering if I can mount the drivers to the front with lots of volume above and below them or if I should make it basically a triangular cylinder sub, with drivers mounted at top and bottom.
Also the help file for WinISD says that rear port velocity of 23 ft/sec is high. My current design peaks at 21 ft/sec at 19Hz. Does that seem acceptable and can ports with greater diameter handle greater air port velocities without noticeable chuffing?
