Punching my values into WinISD its looking like 2 4" ports
or one single 6" port will work much better for my sonosub
design...I'm having trouble locating a 6" flared port however,
and was wondering if the flaring is really necessary with a
6" port, or if I could just use basic PVC?
Tempest driver
10 ft^3
24" diameter tube
with a single 6" port 16 1/4" long, vent mach hits 0.12
with two 4" ports 15 1/2" long, vent mach at 0.07
single 4" port 6 1/4" long returns vent mach of 0.28!! that
isn't gonna be acceptable...
thoughts, ideas, HELP? I would like to track down the port
before this weekend...
