Short answer: the W-King T9. It ranks #53 of 120 large speakers by sound quality, rated 3.6/5, at $111.23; the Treblab HD-Max ranks #104, rated 2.4/5, and costs $123.47, so there is little reason to consider the other one.
The W-King T9 is the better-sounding, deeper-bass choice. A loud stereo party speaker with a wireless microphone for karaoke, lights, a long battery and a power bank. Its bass reaches about 47Hz before falling 10dB, against 60Hz for the Treblab HD-Max. The catch: Peaks in the upper mids which makes it sound a bit harsh.
The Treblab HD-Max is the lighter, tougher option. A very loud, well built boombox with a long tested battery, water resistance, and power bank charging. At 5.1 lbs (2.3 kg) it weighs much less than the W-King T9 at 10.1 lbs (4.6 kg). It is rated IPX6, while the W-King T9 has no water resistance. Watch for: Boosted upper bass, not much lower bass.
Buy the W-King T9. It is rated higher for sound quality than the Treblab HD-Max and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
