Short answer: the Meyer Sound Ultra X23 on measured sound quality, the Alcons Audio SR9 on price. The Meyer Sound Ultra X23 ranks #20 of 39 compact 5 to 6.5-inch pa speakers, rated 3.3/5, at $5,540. The Alcons Audio SR9 ranks #26, rated 3.2/5, at $2,950, $2,590 cheaper.
The Meyer Sound Ultra X23 is the deeper-bass choice. A very wide coverage self-powered speaker, built for close-in fill with listeners far off to the sides. Its bass reaches about 71Hz before falling 3dB, against 150Hz for the Alcons Audio SR9. The catch: Manufacturer measurements give a 1.73 standalone and 4.53 ideal-subwoofer preference score, well below its narrower-coverage Meyer Sound Ultra X20 and Meyer Sound Ultra X22 siblings, with a 4.1dB reference band.
The Alcons Audio SR9 is the more accurate choice. A passive ribbon fill speaker with a wide horizontal pattern, made for discreet front fill and speech coverage. Its measured preference score, a predictor of how neutral it sounds, is 2.46 against 1.73 for the Meyer Sound Ultra X23. 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 Meyer Sound Ultra X23 if sound quality is the priority over the price, or the Alcons Audio SR9 if the price is the priority over sound quality.
