JBL Partybox Encore Essential 2 vs Zealot S89

The Essential 2’s dome tweeters over cone appear better off axis, though it is missing a little bit of upper bass.

JBL Partybox Encore Essential 2 ranking card

Older model: the JBL Partybox Encore Essential (ranked lower, rated 4.2/5).

Pros: A compact 6.2kg party speaker with 100W output, 110dB maximum level, a 15-hour claimed battery, app-based 7-band EQ, dynamic lighting, USB playback, guitar and mic inputs, and Auracast linking. Independent testing finds a balanced midrange, genuinely punchy low bass and enough output for a backyard gathering; its dome tweeters also improve the earlier Encore’s high-frequency behavior. Measured bass extension of 42Hz (-10dB).

Cons: 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. Bluetooth latency can cause lip-sync issues, its IPX4 rating only covers splashes, and it omits the wireless microphones bundled with the non-Essential Encore 2.

Zealot S89: $259.99 Amazon AliExpress eBay

Zealot S89 ranking card

Pros: A 7.3kg boombox with a claimed 36Hz bass extension, 40-hour battery life, IPX6 protection, USB-C charging, aux, USB and microSD playback, TWS and multi-speaker PartyAdd. Listener comparisons find it capable of very high output and substantial bass for outdoor use. A great value for its bass, battery life and maximum volume. Measured bass extension of 36Hz (-10dB).

Cons: At high volume, listener reports describe the bass as loose or muddy and the overall balance as less clear than better boombox speakers. The heavy cabinet and basic finish also make it less polished for daily portability, while its multiple EQ modes cannot substitute for a genuinely neutral tuning.
