These are not really the same size class, and that is the honest framing here. The Wet Sounds WS-L ranks #33 of 54 party speakers by sound quality at $524.99; the Turtlebox Grande ranks #81 of 113 boombox speakers by sound quality at $730.
The Wet Sounds WS-L is the longer-running option. A rugged marine party speaker built for boats and beaches, fully waterproof with a removable long life battery and app controlled lights. It is rated for 40 hours of battery against 25 for the Turtlebox Grande. It has an adjustable EQ, which the Turtlebox Grande lacks. The catch: 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.
The Turtlebox Grande is the lighter pick. A rugged, submersible, crush-proof speaker with a 10 inch woofer and a battery that lasts for days. At 18.8 lbs (8.53 kg) it weighs noticeably less than the Wet Sounds WS-L at 24.9 lbs (11.3 kg). It plays in stereo from a single unit, unlike the Wet Sounds WS-L. The tradeoff: In YouTube sound samples it sounds only okay, and bass is shallow for a 10 inch woofer, only down 10dB at about 55Hz.
Buy the Wet Sounds WS-L at $524.99 for a party speaker, or the Turtlebox Grande at $730 for a boombox speaker instead.
