What are "Full range speaker"

Hey, Ohhwy61:

Would you consider the Avantegarde Solo to be full range (and a single driver) speaker?

(It is kind of a quasi full range single driver speaker. I agree with you that regular dynamic type speakers do not lend themselves to single driver/full range speakers.)

The AV Solo is a two way system with a separate woofer and tweeter drivers. Besides, it doesn't go deep enough in the bass.

I'm still trying to understand S23chang's comments.

Ok Onhwy61, how about the Loth-X Bard?

Twl's post, quick specs.

single driver, 24Hz-20kHz at 108db with 1 watt input.

Some fine single drivers
Western Electric/Altec 756a and 728b
AER drivers
Lowther drivers

If you would consider coaxial speakers as single driver, then you'll have tons of this type of single driver full range speakers from vintage to modern.
They sound extremely open and effortless except they're big. in cabinet size.
