Vas question

High Efficiency Speaker Asylum

Need speakers that can rock with just one watt? You found da place.

How is it that a woofer, say a 12" woofer, with an FS of 21hz, a Qts of .25, and a Vas of 10.21^3', can have an optimized sealed cab of only 1.65^3', but a ported cab (tuned to FS), has to be nearly twice as big. I would have thought it would be the other way around.

Also, if the Vas requirement of two speakers is additive, does that hold true for other parameters, such as the Q factors? (I'm referring to designs employing more than one woofer in a cabinet).
