Short answer: the OSD Audio AP650, if you are buying new. The Revel M80XC ranks higher than it (#2 vs #10 of 13 outdoor speakers, 3.9/5 vs 2.9/5) but is discontinued, so only consider it used; the OSD Audio AP650 is still sold new at $199.99.
The Revel M80XC is the more accurate, deeper-bass pick. Klippel NFS testing by Audio Science Review yields an impressive preference score of 4.07 (6.95 with subwoofer) for an all-weather cabinet. Its measured preference score, a predictor of how neutral it sounds, is 4.07 against 2.12 for the OSD Audio AP650. Its bass reaches about 82Hz before falling 3dB, against 95.2Hz for the OSD Audio AP650. The tradeoff: Price is relatively high at $900 per pair.
Why pick the OSD Audio AP650: Affordable $200/pair price with a solid 6.5” woofer. Watch for: Preference score is 2.12 (5.30 with sub) due to notable mid-frequency irregularities and uneven directivity through the crossover handover.
Buy the OSD Audio AP650, since the Revel M80XC is discontinued and only worth hunting down used.

Revel M80XC: $900 per pair Discontinued eBay
Pros: Klippel NFS testing by Audio Science Review yields an impressive preference score of 4.07 (6.95 with subwoofer) for an all-weather cabinet. Wide and uniform horizontal directivity (+/-60 degrees) and smooth predicted in-room response (0.728 smoothness). Generous 8” aluminum cone woofer produces clean output and solid bass extension down to 67Hz (-6dB) with sturdy IP56 weatherproofing and high 91dB sensitivity. Measured bass extension of 82.0Hz (-3dB).
Cons: Price is relatively high at $900 per pair. Treble resonance around 4.5kHz and port-less sealed alignment require substantial amplifier power to hit reference levels in wide-open outdoor spaces. Discontinued.

OSD Audio AP650: $199.99 per pair Amazon eBay
Pros: Affordable $200/pair price with a solid 6.5” woofer. Klippel NFS tests show reasonably smooth listening window directivity in the lower registers and bass reaching 74.7Hz (-6dB). High 90dB sensitivity makes it easy to power with inexpensive multi-zone amplifiers. Measured bass extension of 95.2Hz (-3dB).
Cons: Preference score is 2.12 (5.30 with sub) due to notable mid-frequency irregularities and uneven directivity through the crossover handover. High-frequency treble rolls off early compared to indoor hi-fi designs.
