Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Teufel Rockster Air ranks #9 of 14 battery-powered PA speakers by sound quality; the Diamondboxx L2 ranks #31 of 43 party speakers by sound quality at $1,000.
Why pick the Teufel Rockster Air: Exceptional 58-hour battery (31 hours at full volume with ECO mode). The catch: Peaky midrange, not very natural sounding.
What the Diamondboxx L2 does well: High-fidelity Class A/B amps with good bass response and clear sound at all volumes. The tradeoff: Boomyness in the 100Hz region.
Worth knowing: the Teufel Rockster Air has been discontinued and is hard to find new at this point.
Buy the Teufel Rockster Air if you want a battery-powered PA speaker. Buy the Diamondboxx L2 if you want a party speaker instead.
If battery life is a priority, the Diamondboxx L2 is rated for 48 hours versus 30 hours for the Teufel Rockster Air.
