These are not really the same size class, and that is the honest framing here. The JBL Xtreme 5 ranks #2 of 120 large speakers by sound quality at $399.95; the Turtlebox Gen 3 ranks #105 of 113 boombox speakers by sound quality at $430.
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 65Hz for the Turtlebox Gen 3. At 6.4 lbs (2.9 kg) it weighs noticeably less than the Turtlebox Gen 3 at 10 lbs (4.54 kg). It supports AAC Bluetooth, which the Turtlebox Gen 3 lacks. The catch: High priced.
The case for the Turtlebox Gen 3: A loud, waterproof and crushproof outdoor speaker with a big battery, device charging and party mode linking. It keeps a wired aux input, which the JBL Xtreme 5 lacks. The tradeoff: Sounds basically identical to the original and the Turtlebox Gen 2: each generation mainly added features, not sound quality.
Buy the JBL Xtreme 5 at $399.95 for a large speaker, or the Turtlebox Gen 3 at $430 for a boombox speaker instead.
