These are not really the same size class, and that is the honest framing here. The JBL Partybox 1000 ranks #4 of 13 large party speakers by sound quality at $1,099.95; the Sony ULT Tower 5 ranks #5 of 53 party speakers by sound quality at $448.
Why pick the JBL Partybox 1000: A huge, powerful party speaker with excellent sound, deep bass, mic and guitar inputs, and wheels for moving it. The catch: Very large and heavy.
The Sony ULT Tower 5 is the battery-powered, lighter choice. A powerful party tower with deep bass, a removable long battery, and mic and XLR inputs for karaoke or DJ use. Its battery is rated for 20 hours, while the JBL Partybox 1000 needs an outlet. At 28 lbs (12.7 kg) it weighs much less than the JBL Partybox 1000 at 75 lbs (34 kg). It is rated IPX4, while the JBL Partybox 1000 has no water resistance. The catch: It has a shorter 20-hour battery claim than the Sony ULT Tower 7’s 30 hours, no wheels, and only IPX4 splash resistance.
Buy the JBL Partybox 1000 ($1,099.95) for a large party speaker; the Sony ULT Tower 5 ($448) suits a party speaker instead.
