Short answer: the Teufel Rockster. It ranks #7 of 11 large party speakers by sound quality; the Sony ULT Tower 10 ranks #9.
On the Teufel Rockster side: Loudest battery powered speaker. Deeper bass than the Soundboks 2/3. The catch: Extremely heavy, not easy to carry. Not stereo. Only available in Europe.
What the Sony ULT Tower 10 offers: Louder than the Partybox Ultimate. Includes a wireless microphone. Set against that: Not as deep of bass and loses more bass at high volume even compared to the lower end Partybox speakers.
Buy the Teufel Rockster if sound quality matters more than the price. Buy the Sony ULT Tower 10 if the price matters more than sound quality.
If sound quality matters at all to you, skip the Sony ULT Tower 10. It ranks near the bottom of the 11 large party speakers, so look higher up the list instead.
