Turtlebox Grande Speaker delivers powerful, concert-level sound in Turtlebox's largest and loudest speaker design. Producing up to 126 decibels of sound through a 1.25-inch titanium tweeter, 10-inch woofer, and dual Class D digital amplifiers, the Grande is built to provide serious audio performance for boats, fishing trips, outdoor gatherings, tailgates, and other adventures where bigger sound is needed.

Engineered for demanding outdoor environments, the Grande features an IP67 waterproof rating for fresh and saltwater, floats, and can be submerged in up to 3 feet of water for 30 minutes. Its rugged construction is also designed to withstand drops, crushing, and dust. A 158Wh lithium-ion battery provides more than 40 hours of playtime on a single charge, making it well suited for long days and extended trips.

Party Mode allows the Grande to pair with an unlimited number of compatible Turtlebox Original Gen 3, Cub, Ranger, and Grande speakers for expanded sound. True Wireless Stereo provides dedicated left and right stereo pairing, while Bluetooth 5.4, USB-C device charging, a built-in microphone port, stainless steel tie-downs, and a pro audio mount add versatility for use on and off the water.
