That puts the tuning around 60hz if it was a true TL. It doesn't appear to be so because of the front chamber being wider than the actual line. It looks like a pressure chamber before the line which will have an affect on the actual tuning frequency. So really, I don't know either.
I would assume that as you go below the transmission line's tuning, the line would act more like a port and you would have them in more of a lower tuned enclosure. That's probably why he called it a bass reflex/TL enclosure.
