speaker enclosure calculations
Posted 12th February 2011 at 08:17 PM by seniordesign
Hello,
I am currently constructing a sealed enclosure for a 12 inch woofer with a resonant frequency of 38 Hz.
My senior design mentor wants me to alter the resonant frequency of the speaker by using a smaller enclosure to shift the frequency at which it resonates to 100 Hz. Its is being used in an interferometer, not for playing music, so I do not need to worry about sound quality.
Does anyone know of the calculations used to alter the Fs?
Thanks!

Fc = system resonant frequency
Vb = box volume
Fc = (Qtc/Qts) * Fs
Vb = Vas/((Qtc/Qts)^2)-1Posted 15th February 2011 at 03:30 PM by hitsware
