Short answer: the JBL Partybox Encore Essential. It ranks #7 of 75 boombox speakers by sound quality at $299.95; the Demerbox DB2 ranks #51 and costs $400, which makes this an easy call rather than a real tradeoff.
What the JBL Partybox Encore Essential offers: JBL Partybox Encore Essential uses 135mm woofer + 2x 44mm tweeters. Its 5.9 kg, claimed 6 hours (Manufacturer specified) battery life, IPX4 protection, aux input, up to 110dB and stereo playback make it a practical option for its intended room or portable use. Watch for: Bass is limited by its 38Hz specification.
What the Demerbox DB2 offers: 40+ hour battery life even at higher volumes (real-world: ~14 hrs with phone charging mixed in). Built from a Pelican case - nearly indestructible and waterproof (IP67). Multi-pair up to 6 units. Doubles as power bank and waterproof container. Watch for: Bass is not as deep as better speakers. Very overpriced.
Buy the JBL Partybox Encore Essential. It ranks higher for sound quality than the Demerbox DB2 and costs less, so there is no real case for the other one.
If battery life is a priority, the Demerbox DB2 is rated for 40 hours versus 6 hours for the JBL Partybox Encore Essential.
If water resistance matters to you, the Demerbox DB2 at IP67 (brief submersion) holds up far better than the JBL Partybox Encore Essential at IPX4 (splashing).
