Onn Large Party gen 2 costs much less than the discontinued Sony GTK-XB90 and has comparably uneven tuning per our notes. They rank 19 of 51 and 47 of 51.
GTK-XB90 pairs EXTRA BASS technology with LED lights synced to the beat and Fiestable DJ controls, but our notes describe muddy, shallow bass with a weird midrange peak and rolled-off treble, and Sony has discontinued it.
Onn Large Party gen 2 has its own karaoke mic/guitar inputs, FM radio and wheels for far less money, though Consumer Reports found its own bass boomy and treble smeared.
Buy the Onn Large Party gen 2 over the discontinued Sony GTK-XB90: it’s much cheaper with similarly uneven tuning either way.
The Sony GTK-XB90 is not a sound-quality pick. It sits near the bottom of the 51 party speakers; there are better options higher up.
There is a real gap in water resistance: the Onn Large Party gen 2 at IPX4 (splashing) against the Sony GTK-XB90, which has no water resistance.

The Two Speakers In Full
Onn Large Party gen 2: $129 Walmart eBay
Pros: A remarkably full-featured, manageable 9.5kg party speaker: wheels and handle, FM radio, aux, USB-A charging, mic and guitar inputs with karaoke echo, and Party Sync. Independent testing confirms bass with real impact and enough output for a large room; it is a clear improvement over the Gen 1 for low-end weight.
Cons: The low price shows in the refinement. Consumer Reports found boomy bass, hazy/grainy mids, a prominent smeared treble and a narrow, two-dimensional soundfield; it also notes distortion or other audio issues. There is no app or EQ to tame the tuning, and IPX4 only covers splashes rather than rain or immersion.
