I've heard several systems not made by Voxativ that utilize their drivers and the drivers certainly prove to be quite good. They do a good job with fieldcoil magnets. G.I.P. Laboratories, a Japanese company also makes a very good fieldcoil wide range driver that is around 12" in diameter. The downside is the price which is way up there in Feastrix territory (they make a decent fieldcoil full range driver too.
Among the best sounding full/wide range drivers currently available are the models made by the German company AER. The prices range from expensive to crazy expensive, but, I've heard systems employing their drivers that sounded remarkably smooth and lacking in harsh peaks that are common to this type of driver.
It is a bit of a sad state of affairs that some really old, no longer made wide-range drivers remain among the very best ever made. I would take the Jensen M-10/ERPI 4151 13" field coil driver over almost any other such driver out there; add a good tweeter you can have an almost matchless system.
