Hearing the TLS80 transmission line speakers from IMF are what started me on my audiophile journey. Hearing Klipschorns made want to leave the room.
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). |
