Short answer: a tie on sound quality. Both are rated 4.0/5 (#6 and #5 of 22 8-inch pa speakers), so choose on features and fit.
Why pick the L-Acoustics X8: Vendor Spinorama data gives preference scores of 4.29 standalone and 7.09 with an ideal subwoofer, the best standalone score in this ranking. The tradeoff: It is a passive cabinet that needs an L-Acoustics amplified controller.
Why pick the JBL PRX908: High-quality vendor data shows a 5.69 ideal-subwoofer preference score with 58Hz measured extension, backed by JBL’s extensive service network. 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 L-Acoustics X8 or the JBL PRX908 on features: they are rated the same for sound quality at close to the same price.

The Two Speakers In Full
L-Acoustics X8 Passive eBay
Pros: Vendor Spinorama data gives preference scores of 4.29 standalone and 7.09 with an ideal subwoofer, the best standalone score in this ranking. Bass reaches about 71Hz (-3dB) with a deviation of only 1.0dB across the reference band, and the 100° axisymmetric coaxial pattern stays even off axis. It reaches 129dB from a 12kg cabinet with a 35° monitor angle. Measured bass extension of 71Hz (-3dB).
Cons: It is a passive cabinet that needs an L-Acoustics amplified controller. Listening-window narrow-band deviation is 0.363 and predicted in-room smoothness is 0.615, a step behind the best-measuring boxes. Pricing is dealer quoted and high for an 8-inch box.

JBL PRX908: $799.00 Amazon B&H Photo Video Guitar Center eBay
Pros: High-quality vendor data shows a 5.69 ideal-subwoofer preference score with 58Hz measured extension, backed by JBL’s extensive service network. A 12-band parametric EQ with dbx DriveRack feedback suppression and BLE app control carry over the PRX900 series’ engineering into an 8-inch cabinet. Measured bass extension of 63Hz (-3dB).
Cons: Its 126dB peak claim is modest for a main speaker, so pairing with a subwoofer matters more here than with the larger PRX modules.
