Every bass-reflex system has a speaker mounted in a Helmholtz resonator. Helmholtz resonance is what causes a beer bottle to make a tone when you blow into it. Just like the beer bottle frequency is set by the size of the bottle and the neck, speaker tuning is set by the size of the box and the port.

So, you see, it is all related to beer.
