I use Vtc and Atc to calculate the driver cutout, Sd x 1.905cm (0.75in).
I also use it as a 5th segment or compression chamber.
It's also useful for modeling 3 chambered (trifold?) TH like the Keystone design. You cannot fold a 3 chambered constant expansion horn into a perfect rectangular enclosure without changing the flare rate of 1 of the chambers.
I usually make Vtc & Atc cover S1-S2, L12, S2-S3, L23, or big enough to mount the driver inside the chamber like a bandpass enclosure.
