Short answer: both are discontinued, so this only matters if you are buying used. Used, the Sony SRS-XP500 is the better pick: it ranks #15 of 46 party speakers by sound quality (rated 4.0/5), against #43 (rated 2.2/5) for the Sony GTK-XB72. If you want one new, the Sony SRS-XV500 replaces the Sony SRS-XP500 and is rated 4.0/5 at $299.
The Sony SRS-XP500 is the better-sounding, deeper-bass choice. 20W 3-way speaker system with dual passive radiators, well-balanced sound (clear highs, detailed mids, punchy bass). Its bass reaches about 42Hz before falling 10dB, against 56Hz for the Sony GTK-XB72. It has an adjustable EQ, which the Sony GTK-XB72 lacks. Watch for: Not as loud and bass not as deep as a JBL Partybox 100 or JBL Partybox 110.
The case for the Sony GTK-XB72: Exceptional sound quality, powerful bass, vibrant multi-colored LED lights. Watch for: No deep bass at all, weird midrange peak, rolled off treble and overall strange tuning.
Buy the Sony SRS-XP500 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, buy the Sony SRS-XV500, which replaces the Sony SRS-XP500.
