Short answer: the Zealot ZE21 for better sound quality, the W-King X20 for the lower price. The Zealot ZE21 ranks #15 of 73 boombox speakers at $247.41. The W-King X20 ranks #28 at $219.98, $27.43 cheaper.
What the Zealot ZE21 offers: Great value for the bass performance, play time and max volume in the boombox class, though the Zealot ZE41 now beats it out. Watch for: 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 X20 offers: 200W RMS output with 330W peak power, 112dB max volume, exceptional 24-hour battery life with power bank, IPX6 waterproof, EQ with app control and button modes, 7.5-inch subwoofer, Bluetooth 5.3, dual pairing, MicroSD and USB playback, AUX input, TWS stereo mode with 240W combined Watch for: Rising frequency response but upper treble rolled off, 700hz and 1.2khz peaks
Buy the Zealot ZE21 when sound quality outweighs the price for you, and the W-King X20 when the price outweighs sound quality instead.
