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.

@larryi - The OP asked about a folded horn, which is different than a back-loaded horn. The typical example is a Klipsch corner horn or La Scala. As their name implies, they are horns... but the folding reduces the floor space. They fire into the horn, and the rear is a sealed space. |
I may not be entirely correct here, but I think of folded horns as horns and TL as competitors to the ported enclosure. That is, horns gain efficiency through the improved impedance match of the driver to the air via the horn. The TL however AFAIK has similar efficiencies in the high frequencies of a sealed or ported speaker, it’s the deeper and more extended bass that make them worthwhile. I'm sure others will correct me. |
