Short answer: the Onn Medium Party Speaker Gen 2. It ranks #65 of 112 boombox speakers by sound quality (rated 3.1/5) at $90 and is still sold new; the Demerbox DB2 ranks #74 (rated 2.8/5) and is discontinued, so it is only an option used.
The Onn Medium Party Speaker Gen 2 is the better-sounding choice. An affordable waterproof party speaker with a big woofer, lights, a karaoke mic input and FM radio. It links with other speakers (Party Sync Mode), which the Demerbox DB2 cannot. Watch for: Lacking detail compared to the Onn Large Party gen 2 and not as deep of bass.
The Demerbox DB2 is the longer-running, lighter pick. A nearly indestructible waterproof speaker built from a Pelican case, with a 40 hour battery and dry storage. It is rated for 40 hours of battery against 20 for the Onn Medium Party Speaker Gen 2. At 5.4 lbs (2.47 kg) it weighs much less than the Onn Medium Party Speaker Gen 2 at 11 lbs (5 kg). It plays in stereo from a single unit, unlike the Onn Medium Party Speaker Gen 2. Watch for: Bass is not as deep as better speakers.
Buy the Onn Medium Party Speaker Gen 2. It is rated higher for sound quality and still sold new, while the Demerbox DB2 is discontinued.
