I test drove the Questeds and found the 2-way design very pleasing compared to my previous speaker (utilizing a compression driver) and a Seaton Catalyst I had on hand. Don't get me wrong, Mark's speaker was dynamic, precise and powerful - certainly the best HT / compression driver speaker I have ever heard and far surpassing my previous speakers - but I was looking for a wholesale change in sonics and the airiness and sonic signature of the Questeds offered the change I was looking for. Mainly, I wanted to try a design away from compression drivers. I had Klipsch and my Servodrove Runt LCRs (that Mark installed) and though Mark's 12C was superior to my own speakers at the time, I simply wanted a change. I've always been an experimenter and innovative in my choices for the theater and the AMTs / Ribbons were the obvious next thing for me to try.
The Questeds do have limited dispersion both vertically and horizontally, but that was a compromise I was willing to accept. With three rows of seating, there may be some loss to the outer corner seats in the front row but nothing that seems significant during movies. The dispersion limits were more obvious with test tones, etc during set up and placement (that Mark accomplished for me). I didn't want domes either as they tend to blow up under high power.
However, I bought 6 Submersives from Mark and they are awesome!! Moreover, Mark's expertise and service is second to none. He is truly passionate about all things HT and it shows in all his products.
