single driver speakers

think a single driver can do it all, good for you. It can't.

~~~~~~~~~~~~~~~
AS I've frequently mention when speaking of PS drivers, I am not looking fora  BE All End All speaker.
Only need midrange, nothing else,
I have bass and highs in my system. 
I need midrange. 
Thats all I need, nothing else, nothing more. 
My hunch is these new PS are exactly what i've been looking for all these decades, but could not figure out the puzzle.
I've got all the pieces now,  the puzzle will soon be completed.

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.

~~~I;ll soon be 66, 
Never been, nor ever will makea   buy ona  SET, I will a  12 tube PP amp for the PS driver I intend to purchase in sept. 
maybe not ideal match, , but will have to work out as my bass speakers are 87db,. SET. won't work. 
I need slam to get the W18's to respond, And I listen to major full orch music, SET again abit anemic for my music needs. 

Again If
anyone here can put up a  fast shooter that will out draw this 
1929 
Field Coil in midrange/vocal PRESENCE.
Please post, and meet at the OK Corral, sundown,.
btw did not care for any of your 3 speaker choices. back to Square 1 The 1929 Field Coil design. 

Few xover/boxes can match this midrange/voice presence. 
Unreal
WE all been on the wrong path to speaker heaven.

Strunz & Farah "Rainmaker" is one of my test tracks.. If a speaker system can get by that track and sound GREAT.. I'm all for it..

RMx Elixirs or RM30, MY MB columns and GRs OB servo system..

I've heard better but 10X my price range and 10X the cost to treat a room to make them work right..

A 1k system was great to get my attention. It took a 10k system, to beat that. AND a 100k system to beat that.. 10k is fine, 1K is even better. :-)

First, I would like to correct something I said above--The Charney speaker that I really liked was the Companion with the AER driver, although the Voxativ driver was a pretty close second (AER had better top end extension).  I would like, someday, to hear the bigger Concerto speaker.  The Charney and Voxativ Ampeggio are the only single-driver systems (not counting coaxial speakers) that I found to be complete in their capability and lacking in excessive tonal coloration.

The realm of fullrange driver systems becomes much more interesting when such drivers are used in multi-way systems.  An ideal system, to me, would be an old Jensen M10 field coil used as a woofer/midrange and a Western Electric 597 field coil tweeter.  The cabinet would have an open back (to allow for cooling of the field coil drivers) so it would be, in essence, an open baffle system.  I've heard such a system with the M10 and a Jensen RP302 tweeter and can only imagine how much better the 597 tweeter would be.  

Nonetheless, I don't think any one particular approach is the be-all-and-end-all.  I have heard plenty of systems using all kinds of wildly different drivers and approaches that sound quite good, although good in different ways.  For the crowd that appreciates the dynamics, immediacy and lively realism of full/wide range drivers, there are other approaches that work well too.  I happen to like multi-way systems with compression driver/horn midranges and tweeters.
