Short answer: the Onn XL Wireless Party Speaker. It ranks #14 of 50 party speakers by sound quality at $249; the Diamondboxx L2 ranks #37 and costs $1000, so there is not much of a tradeoff to weigh.
What the Onn XL Wireless Party Speaker offers: An exceptional value in a party speaker. Includes 2 wireless microphones. Wheels and a built-in handle for easy transport. 5 multicolor LED lighting effects. Control display on the unit. Watch for: A little bright up top, not quite as well balanced as the JBL Partybox 330.
What the Diamondboxx L2 offers: 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. Watch for: Boomyness in the 100hz region. Gets distorted. Too much treble. Too expensive.
Buy the Onn XL Wireless Party Speaker. It ranks higher for sound quality than the Diamondboxx L2 and costs less, so the other one has nothing left to offer.
There is a real gap in water resistance: the Onn XL Wireless Party Speaker at IPX4 (splashing) against the Diamondboxx L2, which has no water resistance.
