Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Zealot S89 ranks #19 of 76 boombox speakers by sound quality at $246.99; the Klipsch Detroit ranks #57 of 82 large speakers by sound quality at $235.99.
The case for the Zealot S89: A 7.3kg boombox with a claimed 36Hz bass extension, 40-hour battery life, IPX6 protection, USB-C charging, aux, USB and microSD playback, TWS and multi-speaker PartyAdd. The catch: At high volume, listener reports describe the bass as loose or muddy and the overall balance as less clear than better boombox speakers.
Why pick the Klipsch Detroit: Dual 1” tweeters + 3” woofers deliver excellent sound detail and robust bass. The catch: Weird boosted upper bass, bass not very deep.
Buy the Zealot S89 ($246.99) for a boombox speaker; the Klipsch Detroit ($235.99) suits a large speaker instead.

The Two Speakers In Full
Zealot S89: $246.99 Amazon AliExpress eBay
Pros: A 7.3kg boombox with a claimed 36Hz bass extension, 40-hour battery life, IPX6 protection, USB-C charging, aux, USB and microSD playback, TWS and multi-speaker PartyAdd. Listener comparisons find it capable of very high output and substantial bass for outdoor use. A great value for its bass, battery life and maximum volume. Measured bass extension of 36Hz (-10dB).
Cons: At high volume, listener reports describe the bass as loose or muddy and the overall balance as less clear than better boombox speakers. The heavy cabinet and basic finish also make it less polished for daily portability, while its multiple EQ modes cannot substitute for a genuinely neutral tuning.
