I have a 5.2 cu.ft. cabinet that I'm tuning by adjusting the length of the 26 sq.in. rectangular port. I'm putting in a vintage Gauss 4580 and using a sweep generator to find the frequency where the cone stops moving. What frequency should I tune this cabinet to to best extend the low end of this speaker? I only need to get to 40Hz, since the 4 string electric bass only goes to 40Hz.
The Gauss 4580 specs are: fs 31Hz, Qms 2.3, Qes .26, Qts .23, Vas 7.0
Thanks,
Tom
(P.S. Gauss WAS owned by Altec in it's last form)
