I don't think I would own a single driver system, but, I have heard such drivers implemented in multi-way systems that sounded very good. The only reasonably smooth, not to peaky sounding single driver system I heard employed the hideously expensive Feastrix fieldcoil driver.
Among the very best two-way systems I have heard is one that employed an old Jensen 13" fieldcoil driver in an open baffle enclosure with a tweeter covering from something like 8khz on up. The system was very clear and dynamic, full and harmonically "dense" sounding and free of gross midrange coloration (lacking the "transistor radio" midrange shout typical of many full-range drivers). The downside is a lack of truly deep bass (not that important to me) and a very high price tag for the Jensen driver/fieldcoil power supply in perfect working order.
Recently, I heard a two-way system made by Surreal Sound that utilizes a Lowther driver modified by Dave Slagle (turned into a fieldcoil driver) as a midrange/high frequency driver. I have heard this driver before and found it to be too peaky and "shouty" for my taste, but, in the Surreal Sound implementation, most of that peakiness had been tamed. The bottom end (from 133 hz on down) is handled by an unusual vertical array of powered woofers in a dipole arrangement (requires equalization to compensate for dipole cancellation). This is one of the very best modern speakers I have heard. The buyer supplies amplification for the midrange/high frequency driver, which being 99 db/w efficient, does not require much power at all (good for me as my current amp only outputs 5 watts). The only obvious weaknesses of the system, to me anyway, is some peakiness/hardness in the upper midrange, and an obvious difference in "speed" of the bass driver and the upper end driver--the integration is surprisingly good, given the blazing speed of the upper end driver, but it is not perfect. I am actually seriously considering purchase of this system.
