I once did some measurements of a sealed isobaric system vs a twice-the-volume sealed box system, same woofer(s) in both. Isobaric theory predicts they'd have identical response. The measured performance was very different; the isobaric system behaved as if the Qtc was about 1.4 times higher than that of the sealed box system.

I have no explanation for this, but if my observations are correct then the theory is not yet mature.
