Single driver vs traditional 3 way loudspeakers


What you prefer , single driver , no crossover, full   range  loudspeakers powered by low power SAT  or traditional 2-3 way design ?
128x128bache
Parts express have full range speakers..yes tweeter is paper wrapped around the cone... but they have been using them since the 40-50s.
can you compare Charney with Tektone or Volti ?

I have never listened to Tektons but Volti yes at the 2015 NY show. Volti was exhibiting a few rooms down and across the hall from Charney. Volti had his large horns and bass unit, the name escapes me at the moment. All electronics were Vinnie Rossi’s Lio preamp and 200w amp with what I think was a Palmer TT.  We listened to ZZ Top LaGrange at loud and clear volumes felt like I was riding a Harley. I felt the sound in my bones but wasn’t drawn into the record like the Charney Concerto does. Sounded somewhat flat in comparison and uninvolving. The Voltis rocked out and delivered clean clear sound no question but lacked the X factor for me. Just my opinion...
