Agreed about the JBL Aeon series - blech. I've heard several rooms with architectural speaker products from both Genelec (the AIC25 and AIW 25/26 - both are active and bypass amplification requirements) and EAW whose SMS surface mount speakers are quite nice. Both are highly regarded professional monitoring/loudspeaker companies and make fine products for commercial applications. Try to avoid home or "prosumer" products in a commercial environment - buy products designed for the job they are supposed to do.
