Short answer: the Teufel Rockster 2. It ranks #4 of 13 large party speakers by sound quality, rated 4.7/5, at $1,269.94. The Altec Lansing SoundRover Pro 650 ranks #13, rated 2.0/5, at $299.99, $969.95 cheaper, not enough of a saving to outweigh the sound-quality gap.
The case for the Teufel Rockster 2: Sounds better and more evenly tuned than the JBL Partybox 720. The tradeoff: Not quite as deep bass as the JBL Partybox 720.
Why pick the Altec Lansing SoundRover Pro 650: A 15-inch woofer and horn-loaded tweeter in a wheeled cabinet with a trolley handle, at a much lower price than the other large party speakers here. The tradeoff: Erin’s Audio Corner’s Klippel measurements are among the worst we rank: the listening window swings over an 8.4dB span between 300Hz and 5kHz, the predicted in-room response is very uneven (0.24 smoothness), and the preference score is -0.72 (1.81 with an ideal subwoofer).
Buy the Teufel Rockster 2. It is rated higher for sound quality, and the $969.95 saving on the Altec Lansing SoundRover Pro 650 is not enough to make up the difference.

The Two Speakers In Full
Teufel Rockster 2: $1,269.94 eBay
Pros: Sounds better and more evenly tuned than the JBL Partybox 720. Horn-loaded tweeter gives far more consistent off-axis sound, unlike the Partybox 720’s dual tweeters, which suffer from comb-filtering interference. Gets louder without distorting: the Partybox 720 starts breaking up at high volume well before this does. Projects clearly over long outdoor distances, covering a large area evenly.
Cons: Not quite as deep bass as the JBL Partybox 720. Bass output drops off further at high volume.

Altec Lansing SoundRover Pro 650: $299.99 each Amazon eBay
Pros: A 15-inch woofer and horn-loaded tweeter in a wheeled cabinet with a trolley handle, at a much lower price than the other large party speakers here. A wireless microphone and a tripod stand come in the box, and it adds a guitar input, a 1/8-inch aux input, USB and SD playback, USB charging ports and LED lighting. Two can be paired for stereo. Measured bass extension of 60Hz (-3dB).
Cons: Erin’s Audio Corner’s Klippel measurements are among the worst we rank: the listening window swings over an 8.4dB span between 300Hz and 5kHz, the predicted in-room response is very uneven (0.24 smoothness), and the preference score is -0.72 (1.81 with an ideal subwoofer). Bass only reaches about 60Hz (-3dB) and 56Hz (-6dB) despite the 15-inch woofer, and horizontal coverage averages a narrow 30 degrees. It has no battery and no app.
