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.

Another variation is the "full range" four inch Jordan driver in a transmission line cabinet.  I wanna say Carolina Audio (among others) sells/sold this breed of animal.  I've never heard this type of speaker, but I once worked with a guy who owned a pair swore by it.

Check out Charney Audio, Somerset, NJ.  I own his Concerto horn speaker.  You can see my commentary on his web site.

I recently ran across the Audio Nirvana website. Anyone familiar with these full range drivers or their 300B SET amplifier which is very reasonably priced at $1550?
Thanks for all your informative responses!
