Short answer: the JBL Partybox Encore. It ranks #6 of 75 boombox speakers by sound quality at $230; the Demerbox DB2 ranks #51 and costs $400, which makes this an easy call rather than a real tradeoff.
What the JBL Partybox Encore offers: JBL Partybox Encore uses 135mm woofer + 2x 20mm tweeters. Its 6.3 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. It ranks higher for sound quality than the Demerbox DB2 and costs less, so the other one has nothing left to offer.
There is a real battery-life gap here: the Demerbox DB2 is rated for 40 hours, the JBL Partybox Encore only 6 hours.
There is a real gap in water resistance: the Demerbox DB2 at IP67 (brief submersion) against the JBL Partybox Encore, which has IPX4 (splashing).
