Turtlebox Grande

The Turtlebox Grande is the brand's biggest, loudest speaker — built to fill the widest open spaces and outlast the longest days. Tailgate, job site, branding pen, sandbar, or back porch, the Grande throws concert-level volume (a genuine 126 decibels) and keeps the music going for 40+ hours on a single charge.

It's engineered for the places other speakers don't survive. The Grande carries an IP-67 rating — fully waterproof in fresh or saltwater, dustproof, and buoyant, so a tumble off the boat is no big deal. It's drop-proof and crush-proof too, with stainless steel tie-downs, rubber feet, and a pro audio mount so you can strap it down, mount it up, or toss it in the truck and go.

Want to go bigger? Party Mode wirelessly pairs an unlimited number of Turtlebox speakers — Grandes, Gen 3 Originals, Cubs, and Rangers — for true surround sound, or run two in classic left/right stereo with TWS. Bluetooth 5.4 keeps the connection locked in from across the yard, and a USB-C port lets you top off your phone while the playlist rolls. (Note: Party Mode is not compatible with Gen 2 speakers.)
