Short answer: the JBL PRX908. Both are rated 4.0/5 for sound quality (#6 and #7 of 47 8-inch pa speakers), and the JBL PRX908 costs $699 against $2,000 for the L-Acoustics X8, so with nothing between them on sound quality, price settles it.
The L-Acoustics X8 is the more accurate pick. A compact passive 8 inch coaxial speaker with highly accurate sound and wide, even coverage, great as a stage monitor or fill. Its measured preference score, a predictor of how neutral it sounds, is 4.29 against 3.10 for the JBL PRX908. The catch: It is a passive cabinet that needs an L-Acoustics amplified controller.
The JBL PRX908 is the deeper-bass pick. A compact powered 8 inch PA speaker with well balanced sound, Bluetooth app control and feedback suppression for gigs and monitors. Its bass reaches about 63Hz before falling 3dB, against 71Hz for the L-Acoustics X8. It keeps a wired aux input, which the L-Acoustics X8 lacks. Watch for: Its 126dB peak claim is modest for a main speaker, so pairing with a subwoofer matters more here than with the larger PRX modules.
Buy the JBL PRX908. Both are rated the same for sound quality, and it costs $1,301 less than the L-Acoustics X8.
