Voxativ loudspeakers and drivers


I wonder if anyone can explain how Voxativ make their single drivers and loudspeakers to sound so natural and artifact free.  After a recent audition I purchased a pair of Zeth loudspeakers which are truly superb with my 300B amplifiers. Contrary opinions would also be welcome.
Thanks!

Basically they use a whizzer cone instead of a crossover. This can sound very good and needs less power than a speaker with a crossover. It is also like a single point source so should image very well. It was the preferred approach for car stereo for many years. Now modern speaker systems for cars are usually three way - subwoofer, woofer mid range and tweeter - as this increases the accuracy of the sound with less break up distortion and lack of linearity from the use of a single cone.

Let us know how well you live with these speakers. I ask for a reason. I have had a number of single drive speakers. They all eventually wore me out. Just to much of a " good " thing,
Soundsrealaudio: I'd be happy to provide periodic updates. I, too, have had prior single driver and concentric driver loudspeakers....although I've owned the Voxativ Zeth for only 2 months I can confidently say that these are different. The Voxativ drivers are natural sounding without appreciable artifacts at high and lower frequencies. I am aware of some obvious limitations at the frequency extremes. However, they are so well balanced that I'm almost unaware of these limitations while immersed in their organic presentation.  Thanks for your response!
