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 9 ranks #10, rated 4.2/5, at $898, $371.94 cheaper, which does not close the gap in sound quality.
The Teufel Rockster 2 is the better-sounding, tougher choice. A battery powered party PA with excellent, even sound that gets very loud cleanly and covers a big outdoor area. It is rated IPX2, while the Sony ULT Tower 9 has no water resistance. Watch for: Not quite as deep bass as the JBL Partybox 720.
The Sony ULT Tower 9 is the longer-running, lighter pick. A battery powered party tower with good sound, a long battery, karaoke inputs, and a detailed app EQ. It is rated for 25 hours of battery against 15 for the Teufel Rockster 2. At 65.3 lbs (29.6 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 tradeoff: 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 $371.94 you would save on the Sony ULT Tower 9 does not close the gap.
