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 ?

On single drivers the  frequency response tilts steeply upwards from bass to treble there's Beaming at high frequencies,  top end marred with ripples and IMD is a problem and they aren't full range. Other than that they should be fine. 

KEF likes to do single driver point source speakers.

Someone seems to be confusing single-driver with concentric drivers. 

Tannoy does a nice job with concentric drivers.
