OP: go over to the Multi-way speaker forum and you'll find lots of helpful and knowledgeable people with very strong opinions to share. :)
Differences Between Folded Horn Speakers and Transmission Line Speakers
I've been looking at various DIY speaker builds and came across a folder horn speaker and I've also seen transmission line speakers. I've tried to google the differences in the two, as they look similar, but I suspect that there are differences. The only visual difference that I've noticed (I've only seen one folded horn, so the comparison pool is very small) is that the folded horn seem to have a larger opening than the transmission line speakers. Maybe it's just the one speaker that I saw, so I don't know that would always be the case. I'm hoping someone on the forum is much more knowledgeable about these things than I am.

I heard the PMC Transmission Line Speakers at CAF 2023 powered with an Advance Paris Integrated amplifier and it did sound remarkably clear to my untrained ears. However, any speaker that has ports down low against the floor worries me about critters getting inside. https://pmc-speakers.com/technology/atl/

Ported speakers tend to require more experimentation to get setup optimized than sealed speakers. The payoff, if you can find a good placemeny, is higher efficiency. This IS a big deal to those who like low powered amps (like me). I have a local dealer that makes sealed box high efficiency speakers with compression driver midranges. But, the speakers are quite large in size, and even though their custom woofers are 18” in diameter, they don’t go extremely low (tradeoffs are inescapable). |
My next speakers are DIY, Frugel-Horn Joan with Mark Audio MA-200 drivers in the gold color(looks more like copper) No crossovers, single 8" full range driver, combination of transmission line and rear horn loaded. Excellent reviews of the Mk3 and XL versions, have not seen one on the bigger units with the larger drivers I am building. Goal is no sub(s), low power amp, low weight, great full sound. I am likely to build several types of speakers to get the best I can out of the not so easy to tame full time RV we live in.
