Short answer: the Sony ULT Tower Max on measured sound quality, the JBL Partybox 710 on price. The Sony ULT Tower Max ranks #1 of 13 large party speakers, rated 4.8/5, at $1,498. The JBL Partybox 710 ranks #7, rated 4.7/5, at $649, $849 cheaper.
The JBL Partybox 710 is the lighter option. A big, powerful mains party speaker with excellent sound and deep bass, plus wheels and a handle for moving it. At 61.7 lbs (28 kg) it weighs much less than the Sony ULT Tower Max at 124.1 lbs (56.3 kg). The tradeoff: Careful placement is still important for balanced bass.
Why pick the Sony ULT Tower Max: A very loud party speaker, with three big woofers for huge bass at large events. It supports LDAC Bluetooth, which the JBL Partybox 710 lacks. The catch: The same comparison found it 1.2dB behind the JBL in A-weighted loudness and weaker below 40Hz.
Buy the JBL Partybox 710 if the price is the priority over sound quality, or the Sony ULT Tower Max if sound quality is the priority over the price.
