Single driver vs traditional 3 way loudspeakers

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.

Some things got different name , but actually is the same , sausage, and kielbasa, If manufactories say -no crossover  is mean nothing between drivers and amplifiers,    no capacitors , no inductions . If they use capacitors , does not matter how is say--- High pass or Low pass is mean -----CROSSSSSover
