No issues with the Arx planar ribbon, it fills the room just fine with claims from reviewers listening to the A1b as have a huge wide soundstage and that was being compared against a nice dome tweeter speaker(s). Some ribbon/planars sound bad, shrill, small sweet spot, ect and some domes are pretty crappy too, ringing, shrill, bright, ect...
Its all in the system design, crossover and driver intergation and designers end goal of what they want. Not the type.

Also keep in mind that the term "ribbon tweeter" is pretty generic nowadays. The RAAL tweeter is a much different animal when compared to the tweeter in the ARX's or HTD's. in how it works.
Yeah forgot about the additional upgrade charge for the ribbon.
HTD uses a "real ribbon" although its not on the same level as the RAAL and the Arx uses a planar which is alittle different than RAAL, Beston ect type ribbons.
