Short answer: the JBL Partybox Encore Essential 2. It ranks #6 of 113 boombox speakers by sound quality, rated 4.3/5, at $249.95; 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 JBL Partybox Encore Essential 2 is the better-sounding choice. A compact party speaker with balanced sound, punchy bass, mic and guitar inputs, and enough volume for a backyard party. The catch: It is front-facing, so the sound changes noticeably to the sides and behind it, and bass compression reduces kick-drum impact at maximum volume.
The case for the Aiwa Exos-10: 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 JBL Partybox Encore Essential 2. It is rated higher for sound quality than the Aiwa Exos-10 and costs less, so only choose the other one for a particular feature it does better.
