These are not really the same size class, and that is the honest framing here. The Soundcore Boom 2 Plus ranks #29 of 76 boombox speakers by sound quality at $179.99; the W-King T9 Pro ranks #27 of 40 party speakers by sound quality at $171.49.
What the Soundcore Boom 2 Plus does well: Quite a bit lighter than most of the other boombox size speakers. Watch for: Warm tuning meaning a rolled off treble and some upper bass boost.
The case for the W-King T9 Pro: A feature-rich rolling party speaker with dual 6.5-inch woofers, removable battery, TWS pairing, bass presets and music-synced lighting. Watch for: Reviewer comparisons describe the tuning as warm and gritty rather than clean or detailed.
Buy the Soundcore Boom 2 Plus at $179.99 if you want a boombox speaker. Buy the W-King T9 Pro at $171.49 if you want a party speaker instead.
There is a real battery-life gap here: the Soundcore Boom 2 Plus is rated for 20 hours, the W-King T9 Pro only 12 hours.
If water resistance matters to you, the Soundcore Boom 2 Plus at IPX7 (brief submersion) holds up far better than the W-King T9 Pro at no water resistance.

Soundcore Boom 2 Plus: $179.99 Amazon B&H Photo Video eBay
Older model: the Soundcore Motion Boom+ (rated 2.9/5).
Pros: Quite a bit lighter than most of the other boombox size speakers. This speaker will likely move up as we get a good EQ tune that makes it a lot more neutral. Measured bass extension of 39Hz (-10dB).
Cons: Warm tuning meaning a rolled off treble and some upper bass boost. Reasonably deep bass, but not as good as the top ranked.

W-King T9 Pro: $171.49 AliExpress eBay
Pros: A feature-rich rolling party speaker with dual 6.5-inch woofers, removable battery, TWS pairing, bass presets and music-synced lighting. The swappable battery is especially useful for long events, and its strong output gives it much more headroom than compact Bluetooth speakers.
Cons: Reviewer comparisons describe the tuning as warm and gritty rather than clean or detailed. Its claimed output figures should not be mistaken for neutral sound quality, and a large cabinet with no stated water rating is a poor fit for wet outdoor use.
