These are not really the same size class, and that is the honest framing here. The JBL Partybox Encore Essential 2 ranks #6 of 113 boombox speakers by sound quality at $249.95; the W-King T9 Pro ranks #38 of 53 party speakers by sound quality at $171.49.
The JBL Partybox Encore Essential 2 is the lighter, tougher pick. A compact party speaker with balanced sound, punchy bass, mic and guitar inputs, and enough volume for a backyard party. At 13.7 lbs (6.2 kg) it weighs noticeably less than the W-King T9 Pro at 20 lbs (9.05 kg). It is rated IPX4, while the W-King T9 Pro has no water resistance. It links with other speakers (Auracast), which the W-King T9 Pro cannot. Watch for: 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.
Why pick the W-King T9 Pro: A rolling party speaker with dual woofers, a removable battery for long events, stereo pairing, and music synced lights. The tradeoff: Reviewer comparisons describe the tuning as warm and gritty rather than clean or detailed.
Buy the JBL Partybox Encore Essential 2 at $249.95 for a boombox speaker, or the W-King T9 Pro at $171.49 for a party speaker instead.
