single driver speakers

I like full-range drivers, but, I particularly like them as extended range drivers in multi-driver systems. The Jensen/ERPI M-10 field-coil driver with a tweeter, as an example, makes quite an extraordinary system. I also heard a two-way system using the Japanese GIP-4165 field-coil driver (Western Electric clone) and that was killer good too.

As for true full range, single driver systems, the best I've heard is probably the Charney with the Voxativ driver. It delivered the speed and immediacy of single driver systems without sounding harsh, nasal and peaked in the upper midrange and treble range; the primary shortcoming was a lack of high frequency extension. Voxative also makes a very good sounding full range system using its own drivers. A friend utilized a field-coil Feastrix driver in a nice custom system, but, it really needed something to boost the bass response.

Yes I am usinga  4 inch point source (DL off ebay, $200) with a  1963 Magnovox horn tweeter, Wonderful combo, beats any xover/box design I've ever heard in my experience of 40 years. 
Jensen made incredible FC's back in its day. 
The Vox you speak of, is not far off entering my system, maybe late September.
I have bass, so not at all important if the Vox rolls on the low end. High end either, the horn will come in handy, if not needed, off it goes. 
Might end up as a   3 way.
W18E001's dual each channel, + Vox + Magnovox horn. 
We;'ll have to see how testing goes,

btw I've listened to some YT clips of the Feastrex,  speaker seemed a  bit bass shy.  
And at that price, you would expect, solid bass. 
However, Feastrex does offer many models, particularilly their massive NEO magnet driver. But these are out my budget.
The AER lab/germany also  sound  very special, but  not in  my budget.

Folks are completely unaware, _______, of this new 21st C technology that has been around since 1929.
All I can say is
Unreal.
The Hifi Guy

Someone please help me out here...

I am struggling to understand

~~~~~~~~~~~~~~
For 2 years I would look and look, and look over DL's PS drivers on ebay,,having no clue what they were all about, But maybe they were more than something cool looking.
I finally figured out what you , back then in 2018, were *struggling** to grasp.
I;ve got the whole equation, puzzle all figured out now.
Took some experimentation, and thinking, thinking, pondering, tweaking, adding, subtracting.
I just hung on and now have all the answers.
The PS technology is from 1929, and  had some developments over the years, 
Then died away completely, Now has resurfaced as 
The New 21st C Super High Tech Speakers. 
My guess is , if the Tampa bay Audio Show has these New tech speakers, news will spread like wildfire, and you will have a wait time of months to get your order filled. These things are not mass produced. But surely worth the wait. 

Good quality single driver speakers tend to excel in coherency, which to me is a key ingredient for the highest quality sound. That to me alone explains the attraction, regardless of the downside. All designs have advantages and disadvantages. How those factor into a final value judgement is completely up to the individual.

There are also many time and or phase "coherent" multi-driver designs out there to compete. Ohm Walsh/CLS, Thiel, Kef UniQ, Tannoy concentric driver designs, mbl, for example, are some that come to mind. I currently own both Ohm Walsh/CLS (coherent line source) and kef UniQ-based speakers (ls 50s and ls 50 metas).

I’m a tough sell personally for any speaker design that is not inherently "coherent" .

Large speakers with multiple drivers all spread out seldom cut it for me in comparison. Requires a very large room for those to integrate time coherently at ones listening location.

It’s been around for a long time, The point is it will NEVER catch on.
For those that think a single driver can do it all, good for you. It can’t.

OLD hat, old tec.. 300hz and below a round VC speaker with tuned phase plugs.

300 hz and up Small Planars or ribbons. NOTHING even gets close, to that combo, EXCEPT more of the same...

I did hear a few Narrow Baffle LS dome systems that were pretty good.. I’ve use a narrow baffle 10" or less for over 20 years, THAT was the real game changer for me.

A single driver NO WAY..

2 watt amps are fun too, just MOST people don’t use them. It’s as simple as that. The FUN wore off quick for me.. I was 25 or so I’m 66 now.. I still have a SET or two around here.. Cute things.

Kinda’ like Tribbles on Star Trek.

BTW this is POST 40+ in over THREE YEARS.. No it’s NOT what’s to come AT ALL.. Maybe 5 in the last 2 years, AY?

I admire your tenacity if nothing else.. Show me something GREAT. I'm all ears..
