Short answer: the Xtreme 5 is genuinely better, but the Boom 2 is the better value. The Xtreme 5 ranks #2 of 120 large speakers at $399.95; the Boom 2 ranks #10 at $99.99, a difference of $299.96. That’s a big enough gap in price that most buyers should still consider the Boom 2 first.
The Xtreme 5 wins on sound, not just spec sheet numbers. Reviewers describe it as a fantastic-sounding speaker with excellent off-axis dispersion and bass that reaches well below 40Hz, explicitly beating the Boom 2 on both bass depth and clarity. It also plays clean at higher volume, which our notes contrast with the JBL Boombox 4’s tendency to distort. None of that comes stock, though: the default EQ presets are weak, with Signature described as boring and Chill and Vocal as close to unusable, so getting the best sound out of it means running a custom EQ.
The Boom 2 has its own sound issues to work around. It ships bass-heavy and treble-bright out of the box, roughly +5dB hot in the highs, and has sound processing issues where bass notes can disappear at low listening levels, the same complaint noted on the Soundcore Boom and Boost. Our notes say that with stock tuning it would only rank around the middle of the pack; a custom EQ (Oluv’s or Alan Ross’s) is what gets it into genuinely competitive territory for its price.
Both are only partially stereo, using a single central woofer with stereo tweeters rather than a true left/right pair, so the spatial difference between them is smaller than the price gap suggests.
Buy the JBL Xtreme 5 if sound quality is the priority and the price doesn’t rule it out; it’s a clear step up in bass depth and clean output at volume.
Buy the Soundcore Boom 2 if you want most of that performance for a fraction of the cost and are willing to run a custom EQ to fix its stock tuning.
