Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The JBL Boombox 4 ranks #20 of 76 boombox speakers by sound quality at $429.95; the Klipsch Detroit ranks #57 of 82 large speakers by sound quality at $235.99.
What the JBL Boombox 4 does well: Pretty insane output capability for the size. The tradeoff: Pretty overpriced for the category.
The case for the Klipsch Detroit: Dual 1” tweeters + 3” woofers deliver excellent sound detail and robust bass. Watch for: Weird boosted upper bass, bass not very deep.
Buy the JBL Boombox 4 ($429.95) for a boombox speaker; the Klipsch Detroit ($235.99) suits a large speaker instead.

Older models: the JBL Boombox 3 (rated 3.8/5), the JBL Boombox 2 (rated 3.5/5) and the JBL Boombox (rated 2.9/5).
Pros: Pretty insane output capability for the size. IP68 protection and Auracast pairing with other current JBL speakers. Measured bass extension of 41Hz (-10dB).
Cons: Pretty overpriced for the category. Better than the Boombox 3 mostly because there are more 7 EQ bands instead of just 3 and it can be better tuned. Try Oluv’s EQ for it. Out of the box sounds worse than the Boombox 3. No Aux input.
