Short answer: the Teufel Rockster. It ranks #7 of 11 large party speakers by sound quality; the Marshall Bromley 750 ranks #11.
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 Marshall Bromley 750 gets right: Much wider, more consistent off-axis dispersion than the JBL Partybox 720, which only fires forward - the Marshall’s standout feature, sounding about the same from any angle. The tradeoff: Not as deep bass as the JBL Partybox 330 or JBL Partybox 720. Not a great frequency response overall, with some midrange peaks.
Buy the Teufel Rockster if sound quality matters more than the price. Buy the Marshall Bromley 750 if the price matters more than sound quality.
If sound quality matters at all to you, skip the Marshall Bromley 750. It ranks near the bottom of the 11 large party speakers, so look higher up the list instead.
If water resistance matters to you, the Marshall Bromley 750 at IP54 (splashing) holds up far better than the Teufel Rockster at no water resistance.

Marshall Bromley 750: $1,199.99 Amazon
Pros: Much wider, more consistent off-axis dispersion than the JBL Partybox 720, which only fires forward - the Marshall’s standout feature, sounding about the same from any angle.
Cons: Not as deep bass as the JBL Partybox 330 or JBL Partybox 720. Not a great frequency response overall, with some midrange peaks. Only basic bass/treble controls, no full custom EQ like the JBL Partybox 720’s app. Default bass (dynamic mode) is overdone out of the box and needs trimming.
