Short answer: the L-Acoustics X6i. It ranks #4 of 39 compact 5 to 6.5-inch pa speakers by sound quality, rated 3.9/5, at $1,695; the Alcons Audio SR9 ranks #26, rated 3.2/5, and costs $2,950, so there is not much of a tradeoff to weigh.
The L-Acoustics X6i is the more accurate, deeper-bass pick. A small weatherproof coaxial speaker with accurate, even sound and plenty of output for outdoor installs and near field monitoring. Its measured preference score, a predictor of how neutral it sounds, is 4.20 against 2.46 for the Alcons Audio SR9. Its bass reaches about 90Hz before falling 3dB, against 150Hz for the Alcons Audio SR9. The catch: A passive cabinet that needs an L-Acoustics amplified controller such as the LA2Xi, LA4X or LA7.16i.
Why pick the Alcons Audio SR9: A passive ribbon fill speaker with a wide horizontal pattern, made for discreet front fill and speech coverage. Watch for: Bass reaches only about 150Hz (-3dB), the shallowest of the group, so it is a fill and speech box that depends on a subwoofer.
Buy the L-Acoustics X6i. It is rated higher for sound quality than the Alcons Audio SR9 and costs less, so only choose the other one for a particular feature it does better.
