Short answer: the W-King T12. It ranks #21 of 44 party speakers by sound quality, rated 3.8/5, at $379.04; the Marshall Bromley 450 ranks #24, rated 3.7/5, and costs $649.95, which makes this an easy call rather than a real tradeoff.
Why pick the W-King T12: A large, capable karaoke-party package with dual 8-inch woofers, independent bass and treble controls, mic and guitar inputs with echo, USB and microSD playback, USB-A charging and TWS pairing. The catch: Reviewer comparisons find the tuning boxy and less clear than the better-ranked party speakers, so its size and quoted power do not automatically translate to refined sound.
The Marshall Bromley 450 is the longer-running, tougher pick. A balanced, warm sound with a flat midrange that keeps vocals and instruments clear, plenty of bass rumble and enough treble for energetic vocals, per RTINGS’ lab tests. It is rated for 40 hours of battery against 25 for the W-King T12. It is rated IP55, while the W-King T12 has no water resistance. It supports AAC Bluetooth, which the W-King T12 lacks. The tradeoff: It is the quietest of its rivals: both the Soundboks Mix and Teufel Rockster Air 2 play louder, and near max volume the bass recedes and the sound gets less composed.
Buy the W-King T12. It is rated higher for sound quality than the Marshall Bromley 450 and costs less, which makes it the one to get unless you need something the other one does better.

W-King T12: $379.04 Amazon AliExpress eBay
Pros: A large, capable karaoke-party package with dual 8-inch woofers, independent bass and treble controls, mic and guitar inputs with echo, USB and microSD playback, USB-A charging and TWS pairing. Its claimed 25-hour battery and trolley-style form make it practical where high output matters more than compact size.
Cons: Reviewer comparisons find the tuning boxy and less clear than the better-ranked party speakers, so its size and quoted power do not automatically translate to refined sound. It is a 15kg, 75cm-tall speaker with no water rating and no app; the physical tone controls are its only meaningful way to adjust the sound.

Marshall Bromley 450: $649.95 Amazon B&H Photo Video eBay
Pros: A balanced, warm sound with a flat midrange that keeps vocals and instruments clear, plenty of bass rumble and enough treble for energetic vocals, per RTINGS’ lab tests. Drivers on all four sides keep the tonal balance nearly the same from any angle, and M1M Tech Channel found it more open and airy than the Soundboks Mix and Teufel Rockster Air 2, with deeper bass than both. RTINGS measured 18.8 hours of battery from a swappable LiFePO4 pack shared with the Bromley 750, and it adds IP55 protection, two XLR/6.35mm combo inputs, USB-C audio, Auracast and physical bass and treble knobs.
Cons: It is the quietest of its rivals: both the Soundboks Mix and Teufel Rockster Air 2 play louder, and near max volume the bass recedes and the sound gets less composed. The warm tuning lacks some fine treble detail. There is no graphic EQ, only bass and treble knobs, and its stereo spreads left and right channels around the cabinet, so panned elements can land on the wrong side. At 12.3 kg it has a carry handle but no wheels.
