These sit in different size classes, so this is not a straight ranking comparison. The Sony ULT Tower 5 ranks #5 of 53 party speakers by sound quality at $448; the Turtlebox Grande ranks #81 of 113 boombox speakers by sound quality at $730.
What the Sony ULT Tower 5 does well: A powerful party tower with deep bass, a removable long battery, and mic and XLR inputs for karaoke or DJ use. It supports LDAC Bluetooth, which the Turtlebox Grande lacks. It has an adjustable EQ, which the Turtlebox Grande lacks. 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.
The Turtlebox Grande is the lighter, tougher pick. A rugged, submersible, crush-proof speaker with a 10 inch woofer and a battery that lasts for days. At 18.8 lbs (8.53 kg) it weighs noticeably less than the Sony ULT Tower 5 at 28 lbs (12.7 kg). It is rated IP67 against IPX4 for the Sony ULT Tower 5. The catch: In YouTube sound samples it sounds only okay, and bass is shallow for a 10 inch woofer, only down 10dB at about 55Hz.
Buy the Sony ULT Tower 5 at $448 if you want a party speaker. Buy the Turtlebox Grande at $730 if you want a boombox speaker instead.
