These speakers are phenomenal for the price. We have the A5s as fronts, A2.4 center, A3's as rears. Replaced JBL's pro series monitors and some Klipsch with these and it was like the JBLs has socks over the speakers. These image extremely well for the price, are fast, and reach surprisingly deep for the narrow design. That said, they need a sub for true HT or electronic music. We paired them with a PSA dual 18 and it matched perfectly (PSA's 18 is fast enough to keep up with these). They are somewhat directional given the ribbons, but not an issue with our setup. Highly recommend.
You can email Jon at Chane directly with questions on setup, placement, layout, or go to their forums, and he is always personally helpful. We have been a customer for many years, since the first Arx models.
