Short answer: the JBL Partybox Ultimate for better sound quality, the Sony SRS-XV900 for the lower price. The JBL Partybox Ultimate ranks #1 of 11 large party speakers at $1499.95. The Sony SRS-XV900 ranks #10 at $900, $599.95 cheaper.
The case for the JBL Partybox Ultimate: Absolute deepest bass of any Bluetooth speaker. The tradeoff: Very large and heavy.
On the Sony SRS-XV900 side: Can get slightly louder than a Partybox 310. Set against that: Not as deep of bass and loses more bass at high volume compared to the Partybox 310 and every other speaker on this page.
Buy the JBL Partybox Ultimate if sound quality matters more than the price. Buy the Sony SRS-XV900 if the price matters more than sound quality.
If sound quality matters at all to you, skip the Sony SRS-XV900. It ranks near the bottom of the 11 large party speakers, so look higher up the list instead.
If water resistance matters to you, the JBL Partybox Ultimate at IPX4 (splashing) holds up far better than the Sony SRS-XV900 at no water resistance.
