Single driver vs traditional 3 way loudspeakers

Tannoy dual concentric driver...I love mine....

~~~~~~~~~~~~~~~
I have dual WBers, about to make it a  3 way wide bander.
+ my paper tweeter is wonderful, clean realistic vocals, just claen/clear,, About to  go better with a  Be/Nd tweeter davidlouis clone of the scanspaek's $350 each tweeter.
I just love these chnese clones, Are they robbing tecnhology from AER/Voxativ is the Wbers? DavidLouis is, for sure. 
The DLVX8 is a near identical clone of the AER/Voxativ. 
The DavidLouis Be/Nd is pretty close clone of the sacnspeak, 
Though I am againt china stealing techology,, in this instances, it serves me very well.

Your Tannoy tweeter aint gonna beat the Be/Nd tweet.
Besides if I want a Tannoy, DavidLouis has a  near exact clone of that speaker as well.
Not the least bit interesed in a  concentric. 
Us WBer fan-ATICS are crazyyy about our WBers.
Wouldn;'t even consider using any other design as main singer in our system. 

But when you consider AER/Vox/Festrex all 3 big WBer labs employ whizzers.
They must have tested with and w/o whizzers.
To me its not important whizzer or no whizzer, only the acutal sound matters to me.
Still waiting for your imput as to the TB 2145's beaming effect.
I could swear I heard soemthing of that affect in my 2 day testing. .
So if the 2145 does present some beaming,

You've not mentioned PHY, who has been making 'full range' drivers for a very long time. None of them use whizzer cones. They are not any more or less beamy than drivers with whizzer cones and phase plugs. But you could make the argument they sound smoother. That is because breakups cause speakers to have a harsher sound, and whizzer cones can break up and introduce harshness.


The best HF response from the PHY drivers is probably their 6" unit.

Not a single mention of Zu Druids here? Two drivers, no crossover. The imaging is quite spectacular.

Any two drivers design , add extra tweeter must use at least one capacitor ( first order crossover ) at least, If you connect  tweeter direct it will blow away instant 

Yes, the tweeter has a High-Pass filter, but no crossover. We all respond differently to different stimuli and I have traded in all my expensive and exotic equipment for simplicity and purity. When my friends listen they might not be "blown away" like they were with my exotic components, but I find I am drawn to listening now like I never was before. OP asked for opinions. As my listening ability has advanced my tastes have changed... simple circuits and simple transducers do it for me now.
