Based on my measurements, I have made a crude cross-section drawing of the speaker with volumes of enclosures marked in. I will replace this with a better sketch once I have everything measured the inner bass chambers precisely.
Some more detail on individual driver enclosures volumes. Note that I have yet to calculate the inner woofer chambers.
