Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The JBL Xtreme 4 ranks #43 of 120 large speakers by sound quality at $309.95; the Tribit Stormbox Blast 2 ranks #31 of 113 boombox speakers by sound quality at $279.99.
The JBL Xtreme 4 is the lighter option. A rugged, waterproof speaker with clear, punchy sound, a swappable battery, a power bank and excellent real world battery life. At 4.6 lbs (2.1 kg) it weighs much less than the Tribit Stormbox Blast 2 at 19.2 lbs (8.7 kg). It links with other speakers (Auracast), which the Tribit Stormbox Blast 2 cannot. The tradeoff: It cannot produce the deep rumble of a larger speaker, and bass compression increases near maximum volume.
The Tribit Stormbox Blast 2 is the louder option. A big, waterproof party speaker with deep bass, very high volume, a 30 hour battery and two mic inputs. Alan Ross Reviews measured it at 110dB at full volume, against 106dB for the JBL Xtreme 4. It supports AAC Bluetooth, which the JBL Xtreme 4 lacks. It keeps a wired aux input, which the JBL Xtreme 4 lacks. The catch: Sounds quite muddy with the boosted lower and upper bass.
Buy the JBL Xtreme 4 at $309.95 if you want a large speaker. Buy the Tribit Stormbox Blast 2 at $279.99 if you want a boombox speaker instead.
