Short answer: both are discontinued, so this only matters if you are buying used. Used, the JBL Control X Wireless is the better pick: it ranks #1 of 13 outdoor speakers by sound quality (rated 4.1/5), against #5 (rated 3.6/5) for the Revel M55XC.
The JBL Control X Wireless is the more accurate, deeper-bass pick. Spinorama measurements on spinorama.org yield a preference score of 4.51 (7.35 with a subwoofer) with smooth predicted in-room response (0.655 smoothness) and tightly controlled directivity (SPDI deviation 3.14dB) from JBL’s High Definition Imaging waveguide. Its measured preference score, a predictor of how neutral it sounds, is 4.51 against 3.36 for the Revel M55XC. Its bass reaches about 75.5Hz before falling 3dB, against 112.8Hz for the Revel M55XC. Watch for: Bass rolls off rapidly below 66Hz (-6dB) and battery life is modest at around 4 hours at moderate volume.
The case for the Revel M55XC: Audio Science Review measurements demonstrate a 3.36 preference score that leaps to 6.89 with a subwoofer. Watch for: Compact sealed enclosure limits bass output, with -6dB extension at 90.8Hz and rapid low-frequency roll-off below 100Hz.
Buy the JBL Control X Wireless only if you find one used in good condition; both are discontinued, and it is the better rated of the two.

JBL Control X Wireless: $499.95 per pair Active Discontinued eBay
Pros: Spinorama measurements on spinorama.org yield a preference score of 4.51 (7.35 with a subwoofer) with smooth predicted in-room response (0.655 smoothness) and tightly controlled directivity (SPDI deviation 3.14dB) from JBL’s High Definition Imaging waveguide. Independent built-in 30W Class-D bi-amplification and wireless stereo Bluetooth operation make it fully self-contained for patio or outdoor listening without running speaker wire or needing an external amplifier. Measured bass extension of 75.5Hz (-3dB).
Cons: Bass rolls off rapidly below 66Hz (-6dB) and battery life is modest at around 4 hours at moderate volume. The model is discontinued so availability is restricted to existing stock or the pre-owned market. High-frequency extension drops off above 16kHz on-axis.

Revel M55XC: $420 per pair Discontinued eBay
Pros: Audio Science Review measurements demonstrate a 3.36 preference score that leaps to 6.89 with a subwoofer. Smooth off-axis response and tight directivity matching through the crossover handover thanks to Revel’s Acoustic Lens waveguide. Rugged IP56 weather resistance and included InvisiBall mounting hardware make installation straightforward. Measured bass extension of 112.8Hz (-3dB).
Cons: Compact sealed enclosure limits bass output, with -6dB extension at 90.8Hz and rapid low-frequency roll-off below 100Hz. Modest 86.5dB sensitivity means it requires a capable amplifier for open outdoor spaces. Discontinued.
