The Two Speakers In Full
Wet Sounds WS-L: $699.99 Amazon eBay
Pros: A marine-grade party speaker with a 10” woofer, a high-frequency compression driver and two passive radiators, rated for 126dB. IP67 dust and water protection with a salt-spray rated enclosure that can be rinsed after use on saltwater. The removable lithium-ion battery is rated for up to 40 hours at moderate volume and about 9 hours at full output. Bluetooth 5.3, SKAA wireless linking for up to four units in stereo or mono, app control of EQ and RGB lighting, and a stackable cabinet with integrated handles and a mount for elevated placement.
Cons: No independent measurements or side by side tests against other party speakers have been published, so its 126dB rating, bass extension and tonal balance are unverified. At about 11kg (25 pounds) it is a heavy carry, and SKAA linking only works with other SKAA speakers. Wet Sounds doesn’t publish a frequency response or Bluetooth codec support.

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.
