Single vs Multiple driver loudspeakers...

What are the pros and cons between Single Driver loudspeakers and multi-driver loudspeakers? The arguments with single driver loudspeakers are that their simplicity makes them easy to drive, plus the x-over-less setup improves dynamics, not to mention no phase problems. The thing I read is that no single driver can possibly produce the full range of sound, and most necessitate a subwoofer. On the other hand, multi-driver loudspeakers can offer a full range, but some say that more than one driver introduces phasing problems to some degree.

I have a multi-driver system that sounds great. How would a single driver setup improve my sound, if at all? And if single drivers are that much of an improvement, why are they harder to find(at least for me)?

I have also read that multi-driver loudspeaker more than often need to be paired with a high wattage amp because of the lower sensitivity, ranging from 89db and less, while single drivers loudspeakers are great for low powered tube amps because of their higher sensitivity.

Most of this, is what I have read, but never really heard.

Can someone educate me?

I've heard numerous Lowther designs and some single driver or multiple driver speakers using full-range Western Electric 755 and 756 drivers. These are interesting speakers that have an immediacy and liveliness that are almost unmatchable.

Still, the only single driver speakers that I would even consider owning would be a Soundlab U-1.

I've had the pleasure of hearing a pair of Overkill speakers that utilize a manger driver plus a conventional dynamic woofer. The manger driver sounds terrific -- very dynamic and clear sounding. The only significant downside was a touch of hardness (perhaps a narrow band peak of some kind)and severe beaming of high frequencies.

By the way, you can count me in the high efficiency/SET camp.
