These are not really the same size class, and that is the honest framing here. The Zealot ZE51 ranks #16 of 76 boombox speakers by sound quality at $296.39; the Klipsch Detroit ranks #57 of 82 large speakers by sound quality at $235.99.
The case for the Zealot ZE51: Cleaner sound and a wider stereo soundstage than the Zealot ZE41, with less distortion at high volume for better instrumental detail and clarity. The tradeoff: The Zealot ZE41 still wins on raw bass depth and price.
The case for 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 ZE51 at $296.39 for a boombox speaker, or the Klipsch Detroit at $235.99 for a large speaker instead.
If battery life is a priority, the Klipsch Detroit is rated for 20 hours versus 4 hours for the Zealot ZE51.

Zealot ZE51: $296.39 after coupon Amazon AliExpress eBay
Pros: Cleaner sound and a wider stereo soundstage than the Zealot ZE41, with less distortion at high volume for better instrumental detail and clarity.
Cons: The Zealot ZE41 still wins on raw bass depth and price. Large and heavy like the rest of the boombox class, and clarity still isn’t up to dedicated hi-fi speakers.
