What exactly is the theory behind the Constant Beamwidth Technology compared to other designs?

See http://www.xlrtechs.com/dbkeele.com/papers.htm and scroll down to the CBT papers
JBL's design operates with a passive crossover so all you need to do is bi-amp with adding your own subwoofer. I would guess that they use resistors to taper the output but with the line being short and straight it would be much different than what we did. The AES papers will answer your questions better than I can. All I know is that it works and is the best line array approach I've seen for pro audio applications.
