Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Audiocase S10 ranks #12 of 14 battery-powered PA speakers by sound quality at $892; the Diamondboxx L2 ranks #31 of 43 party speakers by sound quality at $1,000.
What the Audiocase S10 does well: One of the loudest in category. The catch: Not great sounding at low volumes.
Why pick the Diamondboxx L2: High-fidelity Class A/B amps with good bass response and clear sound at all volumes. The catch: Boomyness in the 100Hz region.
Worth knowing: the Audiocase S10 has been discontinued and is hard to find new at this point.
Buy the Audiocase S10 at $892 if you want a battery-powered PA speaker. Buy the Diamondboxx L2 at $1,000 if you want a party speaker instead.
There is a real battery-life gap here: the Diamondboxx L2 is rated for 48 hours, the Audiocase S10 only 30 hours.
