Have been a single driver speaker fan for 20 years for their innate coherence/imaging superiority and commissioned a pair 16 years ago which I still use daily. They are rather large transmission line based floor standers that use Fostex F200a drivers ($575 each when last available, 8 inch whizzer-less cones, AlNiCo magnets, EnABL treated, considered by some as the best extended range driver in the world, rated 89 dB/w/m, 8 ohms, 30-20,000 Hz, 27 watts continuous/80 watts peak). Not your garden variety single driver speaker.
The speakers you're describing have no performance specifications given, I surmise they are inefficient, offer very limited ultimate output, and lack almost any bass (typical of most small extended range drivers). Have you auditioned them? Based on content they seem overpriced. Audio Circle's own Omega Speakers would seem to represent a better value. Hope you can at least listen to them before buying them. Looks can be very deceiving, especially around audio gear.
