@sound22card- My post was intended to(directly and concisely) address your questions. Hopefully, that was accomplished, despite my having misspelled, "Thiele/Small".
Reasons
What are the attempted advantages of a TL speaker cabinet with equal sizes channels all the way to the port, as opposed to each channel being wider than the last?
Also, what is being achieved by a decreasing size horn channel compared to an increasing size channel?
Are there any simple answers to these questions? I probably won’t comprehend a high level answer.

Tapering the transmission line, towards the opposite end from the woofer, lowers the woofer’s F3(the woofer’s 3dB down point, according to Thiel/Small parameters) and(combined with proper damping) reduces ripples, in the back-wave’s response, equivalent to what could be achieved with a longer(straight) line. Reversing the taper raises the woofer's F3. http://audiojudgement.com/transmission-line-speaker-design/ http://www.philharmonicaudio.com/ML-TL.html https://en.wikipedia.org/wiki/Transmission_line_loudspeaker |
