Short answer: the Teufel Rockster 2. It ranks #4 of 13 large party speakers by sound quality, rated 4.7/5, at $1,269.94. The Sony SRS-XV900 ranks #11, rated 3.7/5, at $900, $369.94 cheaper, not enough of a saving to outweigh the sound-quality gap.
What the Teufel Rockster 2 does well: Sounds better and more evenly tuned than the JBL Partybox 720. The catch: Not quite as deep bass as the JBL Partybox 720.
What the Sony SRS-XV900 does well: Can get slightly louder than a Partybox 310. The tradeoff: Not as deep of bass and loses more bass at high volume compared to the Partybox 310 and every other speaker on this page.
One note: the Sony SRS-XV900 is no longer in production and isn’t widely stocked new anymore.
Buy the Teufel Rockster 2. It is rated higher for sound quality, and the $369.94 you would save on the Sony SRS-XV900 does not close the gap.
There is a real battery-life gap here: the Sony SRS-XV900 is rated for 25 hours, the Teufel Rockster 2 only 15 hours.

The Two Speakers In Full
Teufel Rockster 2: $1,269.94 eBay
Pros: Sounds better and more evenly tuned than the JBL Partybox 720. Horn-loaded tweeter gives far more consistent off-axis sound, unlike the Partybox 720’s dual tweeters, which suffer from comb-filtering interference. Gets louder without distorting: the Partybox 720 starts breaking up at high volume well before this does. Projects clearly over long outdoor distances, covering a large area evenly.
Cons: Not quite as deep bass as the JBL Partybox 720. Bass output drops off further at high volume.
