In Speaker Builder Magazine in the early 80's there was a gentleman named John Cockroft. He did quite a few experiment sin making short T-lines. The shorter he made them, the higher the stuffing density. As with all things audio. What you gain with one hand you loose with the other. Efficiency drops. Personally a maximally damped sealed enclosure is the cleanest sound. A proper front loaded horn is the best of both with dynamics, again, with the volume penalty. DC to light in a thimble always tend to be a problem.The problem, of course, is that open TLs don't work in small cabinets. The smallest box I've seen it not be an abject outright fail in is the somewhat larger PMC 6, and it still has a big interference dip around 300hz.
