Has anyone ever heard these speakers by Volti Audio?

I've heard both the Vittora (at Greg's Maine shop, before he moved to his purpose-built headquarters in Tennessee), and the Rival at AXPONA this spring. Both are terrific, much less colored than Klipsch (haven't heard the Crites modifications, though Greg spoke highly of them).  The Rivals offer great value for money, and you can get resistors hard wired in specially for your amplifier.  They are on the back of the speaker and can be changed if needed without going into the rest of the crossover.  Cabinetry is nice but hardly Sonus Faber class.  You can choose the wood veneer and grille fabric you like; Greg is happy to advise.  He's a nice guy, and really understands what he's doing.
