These sit in different size classes, so this is not a straight ranking comparison. The JBL Xtreme ranks #72 of 114 large speakers by sound quality at $200; the JBL Boombox ranks #69 of 111 boombox speakers by sound quality at $399.
The JBL Xtreme is the lighter, tougher option. A waterproof stereo boombox with a speakerphone, an aux input, and pairing with other JBL speakers, now discontinued. At 5.3 lbs (2.4 kg) it weighs much less than the JBL Boombox at 11.5 lbs (5.2 kg). It is rated IPX7 against IPX5 for the JBL Boombox. Watch for: Issues with bass distortion at high volumes.
The JBL Boombox is the longer-running pick. A water resistant stereo boombox with a 24 hour battery and linking for many speakers. It is rated for 24 hours of battery against 15 for the JBL Xtreme. Watch for: Treble is not very smooth.
Worth knowing: the JBL Xtreme has been discontinued and is hard to find new at this point. The JBL Xtreme’s replacement, the JBL Xtreme 5, is rated 4.6/5 at $349.95.
Buy the JBL Xtreme at $200 if you want a large speaker. Buy the JBL Boombox at $399 if you want a boombox speaker instead.
