And you're capable of looking up the meaning of a word. Maybe.
Some designers use transmission loading - or variants - for midrange and tweeter drivers. That doesn't have to do with extending the frequency response of those drivers downwards....
Follow Ups:
In the vein of transmission line mids, Bud Fried considered the mid-range line more important than the bass line. The music is mainly in the mids and he felt a proper line was a better loading for mids than a simple closed box that he believed strangled the mids.
I recall the Fried model G, a large 3 way with a version of the variovent for the bass but a line mid-range. The early one had a tube going from the front to the back of the main box. But later ones had a longer 3 fold line. I was around when he was comparing the two lines to decide whether to use the 3 fold one. It was obviously more open and detailed and went into later production.
So I guess you don't see a compelling reason to use a TL for a subwoofer.
There is plenty of info about the sound of a TL for the rest of the spectrum, but what is special about a TL as a subwoofer?
You know, all the possible reasons listed previously.
You probably should pursue a bass reflex design, though.
