Short answer: the Zealot S89 if sound quality matters most, the Soundcore Motion Boom+ if price matters most. The Zealot S89 ranks #16 of 73 boombox speakers at $246.99. The Soundcore Motion Boom+ ranks #47 at $140, $106.99 cheaper.
What the Zealot S89 offers: A great value for the bass performance, play time and max volume in the boombox class. Likely the same internals as the Zealot ZE21 Watch for: On the heavy side. A little rolled off up top and not that balanced through the rest of the range. Clarity isn’t as good as better speakers. Bass EQ is bloated and muddy sounding
What the Soundcore Motion Boom+ offers: 80W stereo from dual 30W woofers + dual 10W tweeters with titanium drivers for treble clarity. 13,400mAh battery for 20 hours (12-15 at high volume). IP67 waterproof, floats, rugged build inspires confidence. Bluetooth 5.3 multipoint pairing, Soundcore app EQ, PartyCast 2.0 mode. USB-C input, USB-A output for powerbank. Watch for: Default presets are all warm sounding with rolled off treble. Will need a custom EQ to get closer to neutral. A shrill sounding 6khz peak comes out when volume is above about 60%. Not much deeper bass than a Motion Boom and a lot less deep bass than other speakers in the class.
Buy the Zealot S89 if sound quality is the priority over the price, or the Soundcore Motion Boom+ if the price is the priority over sound quality.
Battery life favors the Zealot S89: rated for 40 hours against 20 hours for the Soundcore Motion Boom+.
