These are not really the same size class, and that is the honest framing here. The Zealot ZE51 ranks #16 of 113 boombox speakers by sound quality at $235.33; the Klipsch Detroit ranks #81 of 120 large speakers by sound quality at $235.11.
The case for the Zealot ZE51: A big stereo boombox with clean, wide sound and low distortion at high volume for outdoor parties. It has an adjustable EQ, which the Klipsch Detroit lacks. The catch: The Zealot ZE41 still wins on raw bass depth and price.
The Klipsch Detroit is the longer-running, lighter pick. A rugged, fully waterproof stereo boombox with a long battery, fast USB-C charging, and power bank output. It is rated for 20 hours of battery against 4 for the Zealot ZE51. At 5.5 lbs (2.5 kg) it weighs much less than the Zealot ZE51 at 26 lbs (11.81 kg). It is rated IP67 against IPX5 for the Zealot ZE51. The tradeoff: Weird boosted upper bass, bass not very deep.
Buy the Zealot ZE51 at $235.33 for a boombox speaker, or the Klipsch Detroit at $235.11 for a large speaker instead.
