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.

The conversation has continued to stir my curiosity about these two types of speakers. I think I will start with the folded horn. I like floor standing towers. The only design that I have seen that I like thus far is this Fostex BK-12m at Madisound (Fostex BK-12m). I wouldn't want to go with a footprint much larger than that. I'll probably go with upgraded drivers. At this point I'm not sure when I'm going to get around to it, but I'm determined to do it. Once I do I'll revive this thread and post photos of the results. After that I'll find a transmission line design that I like and will then tackle that. yes

@raam RV's are 'tiny homes' that just happen to be mobile....*s*
We still have our 34' Safari that I'd tried various audio abstractions within....built prior to slide-outs which 'simplify' wiring but still makes 'near field listening' a given.
'Real estate' (sq. ft.) is what one doesn't have, the pre-installed audio is usually a bad joke, and the cables are basically 'zip wire'....

Go class D amps; the smaller the 'upstream' the better.  Everything onto a laptop as poss.....  Have the quietest genset or your batteries will not have enough for dinner or even the late snack....and morning java will require propane if you're 'dry' camping. 

Forget 'room treatments'....think 'the space as oversized headphones' and you'll be less frustrated.... I never tried 'room eq' as it would be overkill and another thing to take space you don't have.
Best I could manage was a pair of ESS amt's and a pair of 6'' woofs in the kick of the driver and shotgun seat spaces....The dash player did broadcast and CD's.

You have to....No, Will give a pass from 'phile to Practical....

...unless you've a Prevost or the like.  And, even then, a good pair of b/t headphones will be your biggest friend.

Good listening and luck, J
