Short answer: the Teufel Rockster 2. It ranks #5 of 13 large party speakers by sound quality, rated 4.7/5, at $1,269.94. The Sony ULT Tower 10 ranks #11, rated 3.9/5, at $994.34, $275.60 cheaper, which does not close the gap in sound quality.

The Teufel Rockster 2 is the better-sounding, battery-powered option. A battery powered party PA with excellent, even sound that gets very loud cleanly and covers a big outdoor area. Its battery is rated for 15 hours, while the Sony ULT Tower 10 needs an outlet. It is rated IPX2, while the Sony ULT Tower 10 has no water resistance. The tradeoff: Not quite as deep bass as the JBL Partybox 720.
The Sony ULT Tower 10 is the lighter choice. A loud mains powered party tower with good sound and a wireless microphone included for karaoke. At 63.9 lbs (29 kg) it weighs noticeably less than the Teufel Rockster 2 at 96.5 lbs (43.79 kg). It supports LDAC Bluetooth, which the Teufel Rockster 2 lacks. The catch: Not as deep of bass and loses more bass at high volume even compared to the lower end Partybox speakers.
Buy the Teufel Rockster 2. It is rated higher for sound quality, and the $275.60 you would save on the Sony ULT Tower 10 does not close the gap.
