These sit in different size classes, so this is not a straight ranking comparison. The Tribit Stormbox Blast ranks #2 of 113 boombox speakers by sound quality at $199.99; the JBL Xtreme 3 ranks #18 of 120 large speakers by sound quality at $269.95.
The Tribit Stormbox Blast is the louder, deeper-bass option. A boombox with bass and volume that rival bigger party speakers, quite neutral sound, and a 30 hour battery. Its bass reaches about 43Hz before falling 10dB, against 53Hz for the JBL Xtreme 3. Alan Ross Reviews measured it at 108dB at full volume, against 105dB for the JBL Xtreme 3. It is rated for 30 hours of battery against 15 for the JBL Xtreme 3. The catch: Lacks a bit of detail compared to the top ranked speakers in other size categories, dip at 5.5kHz.
The JBL Xtreme 3 is the lighter option. A loud, waterproof stereo speaker with deep bass, balanced sound and a power bank for charging devices. At 4 lbs (1.83 kg) it weighs much less than the Tribit Stormbox Blast at 12 lbs (5.45 kg). It links with other speakers (PartyBoost up to 100 speakers), which the Tribit Stormbox Blast cannot. The tradeoff: Boosted bass.
Buy the Tribit Stormbox Blast at $199.99 if you want a boombox speaker. Buy the JBL Xtreme 3 at $269.95 if you want a large speaker instead.
