On the JBL Boombox 4 side: Pretty insane output capability for the size.

The Two Speakers In Full
Bumpboxx Flare8 Pro: $499.00 Amazon eBay
Older model: the Bumpboxx Flare 8 (rated 2.6/5).
Pros: Doubles the original Flare 8 to 400W and two 8” woofers with dual tweeters in a retro boombox cabinet with an LED display and light up logo. Two wireless microphones come in the box, alongside a guitar input and a wired mic input for karaoke or live use. Plays from Bluetooth, USB and SD cards, has line in and line out, pairs with a second unit for stereo, and includes a carrying strap and remote. Rated for 10+ hours on its rechargeable battery.
Cons: No independent measurements or tested reviews have been published, so its tonal balance, bass extension and real output can’t be compared with ranked speakers. At about 19 pounds (8.6kg) it is a heavy carry. Bumpboxx doesn’t publish a water resistance rating, frequency response or Bluetooth codec support for it, and there is no app.

JBL Boombox 4: $549.95 Amazon B&H Photo Video eBay
Older models: the JBL Boombox 3 (ranked lower, rated 3.8/5), the JBL Boombox 2 (ranked lower, rated 3.5/5) and the JBL Boombox (ranked lower, 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.
