Short answer: the JBL PRX908. It ranks #6 of 47 8-inch pa speakers by sound quality, rated 4.0/5, at $699; the LD Systems Stinger 28-A-G3 ranks #23, rated 3.5/5, and costs $799, which makes this an easy call rather than a real tradeoff.
The JBL PRX908 is the more accurate choice. A compact powered 8 inch PA speaker with well balanced sound, Bluetooth app control and feedback suppression for gigs and monitors. Its measured preference score, a predictor of how neutral it sounds, is 3.10 against 1.96 for the LD Systems Stinger 28-A-G3. It keeps a wired aux input, which the LD Systems Stinger 28-A-G3 lacks. The catch: Its 126dB peak claim is modest for a main speaker, so pairing with a subwoofer matters more here than with the larger PRX modules.
The LD Systems Stinger 28-A-G3 is the deeper-bass option. A powered PA speaker with two 8 inch woofers, deep bass for its size and presets for use as a top, satellite or monitor. Its bass reaches about 56Hz before falling 3dB, against 63Hz for the JBL PRX908. The tradeoff: Manufacturer measurements show a wide 3.7dB reference band and 0.729 listening-window deviation, so tonal balance is uneven, and the standalone preference score is only 1.96.
Buy the JBL PRX908. It is rated higher for sound quality than the LD Systems Stinger 28-A-G3 and costs less, so only choose the other one for a particular feature it does better.
