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 ?

That is a patented " wide-range coherent transmission-line" design.

Lincoln Walsh - Wikipedia

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.

Most unique!

Charles, right, thank you. I was trying to recall Tonian Labs name.
IIRC Tonian no longer carries the PHY product. He used to be the importer. Samuel Furon of Ocellia has taken over PHY. He has an office in Canada and does distribution from there.

Since the bass can be handled by a subwoofer, its really only important that a full range driver make it to something less than 70Hz or so. That is why I find the 6" PHY appealing, since it can do that (in the right cabinet) with fairly smooth highs. Duke LeJeurne designed a sealed box for this speaker which also employed a pair of rear-firing Fostex tweeters. The main driver had no crossover. I did some pink noise measurements and that design made it to 70Hz fairly well- no leaness, and the rear-firing tweeters helped it with not being beamy in the highs. PHY has a rear-loaded horn design for their 8" and 6" drivers; I'm hoping to hear one of those fairly soon.

OP, why not stop reading this, cut to the chase, listen to some and see if you like them?
Simple question, simple answer.

@clearthinker Regardless of absolute necessity to hear the products yourself (in your own system at some point), I think the thread continues to provide very good information about the single driver approach.  I've learned about some brands.  Super useful.  Thanks for a productive thread folks.

The most full range driver is the ohm walsh driver it covers 9 octaves with an augmented treble driver.
