Short answer: the Zealot S89 if sound quality matters most, the W-King D10 if price matters most. The Zealot S89 ranks #16 of 73 boombox speakers at $246.99. The W-King D10 ranks #53 at $99.99, $147 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 W-King D10 offers: 70W RMS output with 120W peak power, exceptional 42-hour battery life, power bank function, IPX6 waterproof, 106dB max volume, EQ and bass boost, microphone input for karaoke, MicroSD card support, USB playback, TWS pairing Watch for: Upper bass boost, bass not that deep.
Buy the Zealot S89 if sound quality is the priority over the price, or the W-King D10 if the price is the priority over sound quality.
