Short answer: the Meyer Sound Ultra X23. It ranks #15 of 16 compact 5 to 6.5-inch pa speakers by sound quality (rated 3.3/5); the Alcons Audio SR9 ranks #16 (rated 3.2/5).
The case for the Meyer Sound Ultra X23: The widest-coverage member of Meyer’s ULTRA-X20 family, with a 110° x 110° horn for close-in fill where listeners sit far off to the sides. The tradeoff: Manufacturer measurements give a 1.73 standalone and 4.53 ideal-subwoofer preference score, well below its narrower-coverage X20 and X22 siblings, with a 4.1dB reference band.
Why pick the Alcons Audio SR9: High-quality vendor Spinorama data gives preference scores of 2.46 standalone and 6.18 with an ideal subwoofer. 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.

The Two Speakers In Full
Meyer Sound Ultra X23 eBay
Pros: The widest-coverage member of Meyer’s ULTRA-X20 family, with a 110° x 110° horn for close-in fill where listeners sit far off to the sides. Bass reaches 71Hz at -3dB from two 5-inch woofers around a concentric 2-inch compression driver, and a built-in 860W peak amplifier with Meyer processing makes it self-powered. Measured bass extension of 71Hz (-3dB).
Cons: Manufacturer measurements give a 1.73 standalone and 4.53 ideal-subwoofer preference score, well below its narrower-coverage X20 and X22 siblings, with a 4.1dB reference band. Output tops out around 123.5dB, and it is sold only through Meyer dealers.

Alcons Audio SR9 Passive eBay
Pros: High-quality vendor Spinorama data gives preference scores of 2.46 standalone and 6.18 with an ideal subwoofer. The RBN401 pro-ribbon and 120° horizontal pattern make it a discreet ribbon-fill and front-fill box, and the sealed woofers give a smooth roll-off. Measured bass extension of 150Hz (-3dB).
Cons: Bass reaches only about 150Hz (-3dB), the shallowest of the group, so it is a fill and speech box that depends on a subwoofer. It is passive, listening-window narrow-band deviation is 0.463, and the very narrow 15° vertical pattern limits placement.
