Short answer: the JBL Partybox Ultimate. It ranks #1 of 11 large party speakers by sound quality; the Teufel Rockster ranks #7.

On the JBL Partybox Ultimate side: Absolute deepest bass of any Bluetooth speaker. Handle and wheels are convenient. The catch: Very large and heavy. No battery. Note, JBL daisychain is not compatible with any other non-JBL speaker and is possibly a fully digital signal.

What the Teufel Rockster offers: Loudest battery powered speaker. Deeper bass than the Soundboks 2/3. The tradeoff: Extremely heavy, not easy to carry. Not stereo. Only available in Europe.

Buy the JBL Partybox Ultimate if sound quality matters more than the price. Buy the Teufel Rockster if the price matters more than sound quality.
