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.

@mjking57, wow.  Thank you for sharing this much specific information  and top-level advice.  Wish I still had time for prototyping TL's like I did back in the 70's and 80's.

"back in the 70's"

The music was sooooo much better. Big cars, big hair, big LP jackets that I could look for hidden pictures and read without a magnifying glass, big amps and speakers producing huge sound. No earbuds or blue-tooth speakers playing poorly recorded downloaded music. Those were the days.

I miss my big hair.

My daughter decorates the wall of her apartment with some of my old LP’s.

I’m still in love with the first pair of IMF transmission line speakers I heard, which is what sent me on my DIY quest. One thing I learned was, respect for those who had mastered the art of transmission line design. Never could bring myself to outright copy someone else’s design though... always felt like, for better or for worse, part of the calling of DIY speaker builder was to experiment. Alas, almost invariably it was for worse.
