Turtlebox Grande – Built to Be Heard.

At Sunjammers, we know you want to crank up the fun without worrying about your gear keeping up. That’s why we carry the Turtlebox Grande—the loudest, most durable speaker on the water, the beach, or the back of your truck.

Here’s the deal: Most portable speakers either sound weak or fall apart the second they get wet. That leaves you feeling let down and ready to toss it overboard. But the Turtlebox Grande changes the game.

With 126 decibels of concert-level sound, this beast was made to be heard over the wind, waves, engines, or the neighbor’s playlist. Whether you're paddling in West Bay or tailgating at the game, this is the kind of speaker you don't just hear—you feel.

Why locals love the Turtlebox Grande:

IP67 waterproof & submersible—yep, it floats and can chill underwater for 30 minutes.
100% drop, crush, and dust-proof—because Florida fun isn’t gentle.
40+ hours of battery life—on a single charge.
Party Mode = infinite pairing—fill the block, the boat, or the beach with sound.
True Wireless Stereo (TWS)—for true left/right audio pairing.
Bluetooth 5.4 + Touch Controls—easy, responsive, and phone-free.
USB-C port for charging—stay powered off-grid.
Built-in mic—for calls, commands, or spontaneous karaoke.
2 Class D amplifiers + enhanced DSP tuning—aka, rich, deep, clear sound.
10” woofer + 1.25” titanium tweeter—powerful bass and clean highs.
158Wh Lithium-ion battery—because adventures shouldn’t get cut short.
Stainless steel tie-downs + rubber feet—stay secure wherever you set it.

We believe adventure should be loud, fearless, and fully charged—and you shouldn’t have to research 100 models to find the right one. That’s why our team at Sunjammers is here to help. We’ll demo it, answer your questions, and get you ready to roll.
