Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The JBL Xtreme 5 ranks #2 of 120 large speakers by sound quality at $399.95; the Turtlebox Grande ranks #81 of 113 boombox speakers by sound quality at $730.

The JBL Xtreme 5 is the deeper-bass, lighter pick. A large waterproof speaker with deep bass, wide, clean sound at volume and a removable 28 hour battery. Its bass reaches about 43Hz before falling 10dB, against 55Hz for the Turtlebox Grande. At 6.4 lbs (2.9 kg) it weighs much less than the Turtlebox Grande at 18.8 lbs (8.53 kg). It supports AAC Bluetooth, which the Turtlebox Grande lacks. Watch for: High priced.
What the Turtlebox Grande does well: A rugged, submersible, crush-proof speaker with a 10 inch woofer and a battery that lasts for days. It keeps a wired aux input, which the JBL Xtreme 5 lacks. The tradeoff: 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 JBL Xtreme 5 at $399.95 for a large speaker, or the Turtlebox Grande at $730 for a boombox speaker instead.
