Turtlebox Grande: Rugged & Powerful Outdoor Speaker

Overview & Build Quality

The Grande is built tough — featuring an IP67 rating for full waterproofing (can be submerged up to 3 ft for 30 mins), designed to float, and constructed from crush-proof ABS with stainless-steel accents. It’s hefty at around 18.8 lbs, and while the size ensures durability, it may feel cumbersome during long treks.

Audio Performance

Equipped with a 10″ waterproof subwoofer, dual Class D amps, and a titanium 1.25″ tweeter, the Grande delivers up to 126 dB of clean, distortion-free volume. Reviewers highlight its concert-level clarity, ability to cut through engine noise, and punchy bass ideal for outdoor use.

Features & Connectivity

Supports Bluetooth 5.4, allowing seamless pairing of over 100 Grande units in “Party Mode.” Includes True Wireless Stereo (left/right), USB-C in/out, a mic input, and a pro audio stand mount for maximum versatility.

Battery Life

Packaged with a 158 Wh lithium-ion battery, it provides roughly 3 days of playback, making it ideal for multi-day outdoor use without needing a recharge.

If you need a speaker that’s truly waterproof, incredibly loud, and built like a tank, the Turtlebox Grande delivers. It’s ideal for those who demand reliability and performance in extreme outdoor settings. If portability or high-fidelity studio sound is more important to you, lighter or more refined alternatives may be a better fit.
