Single driver speakers. Are they worth considering ?

@vinylbrother, 
If the occasion arises for further listening to the Cube Audio speakers (Especially the 10" Nenuphars) please share your impressions if you do not mind.

Charles, right, thank you. I was trying to recall Tonian Labs name.

@ kenjit1 " KEF likes to do single driver point source speakers. It depends what you want. Single drivers have less highs but perfect dispersion. A 3way speaker has clearer sound but horrible dispersion.

Nonsense.

1. KEF offers zero "single driver" products. At minimum KEF hi-fi speaker systems are coaxial, with two distinct though concentrically mounted drivers.
2. There are numerous products on the market with excellent dispersion properties. Is it your contention that Magico's published assertion that the M3 has "ultra-wide dispersion characteristics" and ultra-low distortion measurements" is false advertising or exaggeration? 
3. Allow me to disabuse you of the notion that single drivers exhibit better dispersion properties than a proper multi-driver system incorporating a high grade tweeter: https://www.soundandvision.com/content/dispersion-show-and-tell 

Currently running Fostex Fe208ESigma in free air with a NAD D3020 and sub. Also running Audio Nirvana 8" alnicos in free air, with a class D icepower ASX125 and sub. I listen at around 58-60db. Krall, Jones, Fagen, Lofgren, Davis, Clapton and similar music. Sold a Primare I30 to finance most of the above pieces. Best decision so far on my personal music journey. Cheers, gotta love this hobby

IMHO single drivers suck.
