Alrighty ported box gurus...as the thread states I'm lookin to port my MASS 12. Here are the specs and what I'm planning to build...All (constructive) input is welcome. Thanks!
T/S:
Fs: 23.6 Hz
Qms: 6.13
Qes: 0.43
Qts: 0.40
Vas: 2.8 cubic feet
Re: 1.58 ohms
BL: 19.8
Le: .50 mh
Xmax: 20 mm
Sensitivity: 89.6 dB (with 1-watt input)
The plan is 1.75cubes (after sub, port and bracing displacement) tuned to 26hz. It will basically be a long and thin truck-style box with a single 4inch port due to physical restraints. Power will be 500rms from the sub channel of a JL 900/5. i know the port is a bit small, but it's relatively low power and winisd shows port velocity will still be pretty low.
Let me know what you think, or if you have a different recommendation.
Thanks!
