Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The W-King T9 ranks #53 of 120 large speakers by sound quality at $111.23; the Soundcore Boom 2 Plus ranks #39 of 113 boombox speakers by sound quality at $169.99.
Why pick the W-King T9: A loud stereo party speaker with a wireless microphone for karaoke, lights, a long battery and a power bank. Watch for: Peaks in the upper mids which makes it sound a bit harsh.
The Soundcore Boom 2 Plus is the louder, deeper-bass choice. A fairly light stereo boombox, easy to carry to the beach or park. Its bass reaches about 39Hz before falling 10dB, against 47Hz for the W-King T9. Alan Ross Reviews measured it at 111dB at full volume, against 106dB for the W-King T9. It is rated IPX7, while the W-King T9 has no water resistance. The tradeoff: Warm tuning meaning a rolled off treble and some upper bass boost.
Buy the W-King T9 ($111.23) for a large speaker; the Soundcore Boom 2 Plus ($169.99) suits a boombox speaker instead.
