Short answer: the Zealot ZE51 for better sound quality, the ION Pathfinder 280 for the lower price. The Zealot ZE51 ranks #15 of 75 boombox speakers at $296.39. The ION Pathfinder 280 ranks #68 at $169.99, $126.40 cheaper.
What the Zealot ZE51 offers: Cleaner sound and a wider stereo soundstage than the Zealot ZE41, with less distortion at high volume for better instrumental detail and clarity. Watch for: 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.
What the ION Pathfinder 280 offers: A practical all-day event speaker with an exceptionally long claimed 68-hour battery, wheels, telescoping handle, FM radio, lighting and a full graphic EQ/presets. RTINGS finds it gets loud with relatively little compression, and its wide dispersion makes it a useful choice for outdoor background music or casual gatherings. Watch for: Out of the box, the midrange and treble are uneven enough to sound alternately honky and dull, and the bass does not extend as deeply as better party speakers. It is heavy, only IPX5 splash-resistant, and cannot produce a true stereo image from one cabinet. Use the EQ before judging its sound.
Buy the Zealot ZE51 if sound quality is the priority over the price, or the ION Pathfinder 280 if the price is the priority over sound quality.
Skip the ION Pathfinder 280 if sound quality matters to you. It ranks near the bottom of the 75 boombox speakers.
