Short answer: the Marshall Middleton. It ranks #34 of 105 large speakers by sound quality, rated 4.0/5, at $215.80. The W-King T9 ranks #50, rated 3.6/5, at $111.23, $104.57 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Marshall Middleton is the better-sounding, deeper-bass pick. Very deep bass for the size/weight. Its bass reaches about 39Hz before falling 10dB, against 47Hz for the W-King T9. At 4 lbs (1.8 kg) it weighs much less than the W-King T9 at 10.1 lbs (4.6 kg). It is rated IPX7, while the W-King T9 has no water resistance. The catch: 5db dip at 1.7kHz and 6.3kHz.
The W-King T9 is the louder option. 80W output power, 106dB max volume, 24-hour battery life, power bank function, Bluetooth 5.3 with 100ft range, TWS stereo pairing with wireless microphone, dual subwoofers, RGB lighting, MicroSD and AUX support, USB-C charging, karaoke capability. Alan Ross Reviews measured it at 106dB at full volume, against 99dB for the Marshall Middleton. The catch: Peaks in the upper mids which makes it sound a bit harsh.
Buy the Marshall Middleton. It is rated higher for sound quality, and the $104.57 you would save on the W-King T9 does not close the gap.

The Two Speakers In Full
Marshall Middleton: $215.80 Amazon $215.80 eBay
Newer model: the Marshall Middleton II, ranked higher, rated 4.1/5, released Jul 2025. It adds app control and adjustable EQ. Battery life goes from 20 to 30 hours. See every Marshall Portable Speakers generation.
Pros: Very deep bass for the size/weight. Measured bass extension of 39Hz (-10dB).
Cons: 5db dip at 1.7kHz and 6.3kHz. 9kHz treble peak. Not a very smooth frequency response. A lot of Marshall’s added dsp echo which cannot be turned off, very distracting and annoying. It’s like forcing you to listen to your music in an echo chamber. Bass is reasonably deep but artificial sounding and flabby, with no attack and no dynamics. Treble is rolled off.
