Short answer: the Sony GTK-XB90, narrowly, for deeper party bass, though neither ranks well in its class. It is built around deep punchy EXTRA BASS, while the 60W GTK-XB60 has no deep bass at all, though both share a weird midrange peak, rolled off treble and overall strange tuning. The XB90’s own bass is muddy and not deep either, so this is a low bar. Both are rated below 3.0/5 among the 43 party speakers, and the JBL Partybox Stage 320, ranked #3 at $499.95, is a better place to start if sound quality matters.
Buy the Sony GTK-XB90 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the JBL Partybox Stage 320 instead.
