I need help

in DIY

My computer is on the fritz. My design software is not working correctly.
I want to create a ported box for this driver.
Re = 6.4 Ohms
fs = 45.00 Hz
Sd. = 132.1 mm
Qts = 0.4542
Qes = 0.4954
Qms = 5.456
Vas = 16.96L
Le = 0.1331 mH
BL = 8.397

Can someone work up the design for me?

    Assuming Sd is in cm^2, not mm...

    23L tuned to 40Hz. 2.5" port is 7.5" long

    What is the goal? Are you looking for a certain box size size or f3?

    Very quickly 14l. Fb 36hz gets you a a slow roll off f3 47, f6 36, f10 29, 21l fb 36 gets f3 35, f6 31, f10 27, and 28l fb 35 gives f3 32, f6 29, f10 26.

    I'm hoping to keep the box size to a modest .5 cu/ft if possible.

    14.6 L at 42Hz. 2" port is 7.5" long. 2.5" port is 12.5" long

    Overlay of 35Hz, 40Hz, 45Hz tuning. Take your pick.
