Single driver loudspeakers

I know some friends who have built single driver horn loudspeakers with 6-7 inch 'full range' drive element and seem very happy with the sound.  However I wonder about those selling 94 db sensitive 12 and 15 inch full range drive elements and recommending 2-3 cubic ft bass reflex cabinets and 7 watt SET amplifiers.  Is it possible for a 15" 'full range" driver driven by 7 watt SET  to provide state of the art sound without audible distortion, deficient frequency extremes and 1950 style sound?  This is an inquiry not a critique.  Thank you for helping me to understand full range drive units.

Hello John,
What is your opinion/experience with the PHY-HP 12 inch driver? It has the reputation of being a superb driver. It was used in single driver designs successfully by Ocellia and Musical Affairs in their products.  97 db sensitive and 16 ohms load.

Rlawry,
I find it interesting that you achieved satisfying treble performance with the 12 inch single driver. Thus my question to johnk regarding the PHY-HP 12 inch. It’s possible he may not be familiar with them.
Charles,
