Single driver speakers. Are they worth considering ?


I don't mean electrostatic. How close to a full range speaker can you come with single driver ?

Enjoying this thread!

Since Covid shut pretty much everything down a year ago, I needed a hobby.

(Idle hands are the devil’s workshop...)

So I’ve been building a lot of speakers. The bulk of which have been full range drivers. These run the full gamut from simple vented book shelf speakers, folded horns, pencils, voigt pipes, BIB enclosures (1/2 wave Horn) and really big double horns. 
There really is something special to my ears that comes from a big a$$ed horn speaker. Are they compromised? Sure they are, what speakers are not? The big double horns have so much “breath” in the sound, so much air . Sound is very unique, and people seem to either love em, or...  As an experiment, my friend bought an old Heathkit 8 watt EL84 based integrated. Synergy was insane. They worked so well together! Such a pleasure to listen to.

Im a fan of the single driver horn speaker. And as was mentioned by someone earlier in this thread, my hearing stops working somewhere around 13khz, so doesn’t really matter much what happens after that. Though I suspect my cat has other feelings on that subject...

Have not felt as though I was missing much in the bass. But I’m not playing organ music, or watching movies, so not really too concerned  about what happens below 40hz

For comparatively little money, and a bit of elbow grease, not that difficult to build and there are some interesting designs out there. Two drivers, some decent plywood, glue and some tools, you can experiment...

Yes, Dale Harder's TLS-1 and TLS-2. Single driver, no crossover. Omni directional speaker with perfect time and phase alignment. Fully coherent 360 degree sound dispersion.

Check out my system page for a pic. 
Looks like fun to build but a lot of work for a single driver system. The bass is still going to doppler distort everything else the driver does. For such a large speaker why not do a two way transmission line speaker. There are excellent passive crossover designs out there or use a digital crossover.
That is a patented " wide-range coherent transmission-line" design.

Not the same as a box speaker transmission line design. Definitely a lot of work to design and build! Nobody else even attempts it like that (1 full range physical driver, no electronic crossover) these days.

It’s a classic design though realized via modern techniques and materials. Different designs...different goals.
