Unless you specifically need extreme battery runtime at high output, the Diamondboxx L2 isn’t worth nearly eight times the price of the Onn Large Party gen 2. They rank 19 of 51 and 38 of 51.
L2’s Class A/B amps fill large spaces at under 50% volume with a claimed 6-48 hour battery depending on output, but our notes describe boominess around 100Hz, distortion, and too much treble for the price.
Onn Large Party gen 2 costs a fraction of the price with karaoke mic/guitar inputs and wheels of its own, though Consumer Reports found its own bass boomy and treble smeared.
Buy the Onn Large Party gen 2 for a fraction of the price and comparable tonal issues. Buy the Diamondboxx L2 only if its extreme battery runtime at high output specifically matters to your use case.
If water resistance matters to you, the Onn Large Party gen 2 at IPX4 (splashing) holds up far better than the Diamondboxx L2 at no water resistance.

The Two Speakers In Full
Onn Large Party gen 2: $129 Walmart eBay
Pros: A remarkably full-featured, manageable 9.5kg party speaker: wheels and handle, FM radio, aux, USB-A charging, mic and guitar inputs with karaoke echo, and Party Sync. Independent testing confirms bass with real impact and enough output for a large room; it is a clear improvement over the Gen 1 for low-end weight.
Cons: The low price shows in the refinement. Consumer Reports found boomy bass, hazy/grainy mids, a prominent smeared treble and a narrow, two-dimensional soundfield; it also notes distortion or other audio issues. There is no app or EQ to tame the tuning, and IPX4 only covers splashes rather than rain or immersion.

Diamondboxx L2: $1000 eBay
Pros: High-fidelity Class A/B amps with good bass response and clear sound at all volumes. Fills large spaces at under 50% volume, comparable to medium bookshelf speakers. Stable bass response even at 15-20% volume. 6-48 hours battery on 400+ watts (9 hours full recharge). Built-in 2.1A USB power for charging devices. Over 1000 recharge cycles.
Cons: Boomyness in the 100hz region. Gets distorted. Too much treble. Too expensive.
