Short answer: the Meyer Sound Ultra X20. It ranks #11 of 39 compact 5 to 6.5-inch pa speakers by sound quality, rated 3.6/5, at $5,540. The Alcons Audio SR9 ranks #26, rated 3.2/5, at $2,950, $2,590 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Meyer Sound Ultra X20 is the better-sounding, deeper-bass choice. A slim self-powered fill speaker with surprisingly deep bass for two 5 inch woofers and a built in amplifier. Its bass reaches about 69Hz before falling 3dB, against 150Hz for the Alcons Audio SR9. Watch for: Its standalone score trails its narrower-coverage Meyer Sound Ultra X22 sibling.
The case for 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 Meyer Sound Ultra X20. It is rated higher for sound quality, and saving $2,590 with the Alcons Audio SR9 does not make up for the sound-quality gap.
