Tuning a Sealed Enclosure

Guys,

This is going to probably sound quite ridiculous, but I am trying to find some information on how to find the tuning frequency of a sealed enclosure? Is it done strictly off of box volume? Please help.

If you know the driver's parameters and the final Q of the system you can find it using this formula.

Qtc * Fs / Qts = Fc

That gives you the system resonance. If you want to find the actual resonance of the enclosure separate from the system, use this one.

(Fc / Fs) * Fs = Fc

You can tune a sealed enclosure by adding objects inside the box to make the airspace smaller:fyi:

Are you talking about the 3dB point or the resonant frequency?
