Short answer: the Zealot S89. It ranks #19 of 113 boombox speakers by sound quality, rated 4.0/5, at $193.58; the Aiwa Exos-10 ranks #44, rated 3.5/5, and costs $399.99, so there is little reason to consider the other one.
The Zealot S89 is the better-sounding, longer-running choice. A great value boombox with deep bass, very high volume, a 40 hour battery and water resistance for outdoor parties. It is rated for 40 hours of battery against 12 for the Aiwa Exos-10. The tradeoff: At high volume, listener reports describe the bass as loose or muddy and the overall balance as less clear than better boombox speakers.
What the Aiwa Exos-10 does well: A loud party boombox with FM radio, a remote, and retro VU meters. The catch: It lacks deep bass: even with bass maxed it rolls off around 50Hz, where the W-King X20 and Zealot boomboxes reach deeper, and it is about 2dB quieter at full volume.
Buy the Zealot S89. It is rated higher for sound quality than the Aiwa Exos-10 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
