Short answer: the JBL Partybox Encore Essential. It ranks #8 of 89 boombox speakers by sound quality, rated 4.2/5, at $329.95. The Aiwa Exos-10 ranks #38, rated 3.5/5, at $159.99, $169.96 cheaper, a saving that is not big enough to make up the sound-quality gap.
The case for the JBL Partybox Encore Essential: JBL Partybox Encore Essential uses 135mm woofer + 2x 44mm tweeters. The tradeoff: Bass is limited by its 38Hz specification.
What the Aiwa Exos-10 does well: Clear, clean treble with good separation of instruments and vocals, and no distortion even near full volume in a side by side test against the W-King X20, where it kept up in loudness at 90%. The tradeoff: 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. It is rated higher for sound quality, and saving $169.96 with the Aiwa Exos-10 does not make up for the sound-quality gap.
If battery life is a priority, the Aiwa Exos-10 is rated for 12 hours versus 6 hours for the JBL Partybox Encore Essential.

Aiwa Exos-10: $159.99 Amazon eBay
Older model: the Aiwa Exos-9 (ranked higher, rated 4.2/5).
Pros: Clear, clean treble with good separation of instruments and vocals, and no distortion even near full volume in a side by side test against the W-King X20, where it kept up in loudness at 90%. A 200W RMS tri-amplified design with a 6.5” woofer and four passive radiators, FM radio with presets, aux and USB inputs, a remote, analog-style VU meters and Party Sync with 100+ speakers.
Cons: 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. Owners comparing it with the Aiwa Exos 9 it replaces find the older model clearer with tighter bass, and the Exos 10 drops the Exos 9’s 5-band EQ (only bass and treble) and removable battery. Claimed battery life is 12 hours.
