The Granite-52 speakers and Granite-10D subwoofer – part of the new ROCK-on outdoor speaker series, are specifically designed to imitate a rock appearance and easily blend in with any outdoor environment.

Made with UV treated, weather-resistant enclosure materials and durable epoxy resin construction, the ROCK-on speakers can withstand the demanding outdoor elements.

Granite-52 is a pair of rock speakers with a 5 ¼ inch woofer and a ½ inch tweeter. They serve as your left and right speakers and have an amazing frequency response that is unmatched by any other rock speaker. They produce a clean, accurate sound.

The ROCK-on subwoofer, the Granite-10D, features high power crossovers that reduce distortions and deliver pure sound. Also, Granite-10D’s port is “S” shaped so water cannot get trapped inside. The Granite-10D brings bass to your outdoor space, something that is greatly needed in today’s rock speaker market. Combined with the Granite-52 speakers which have a matching finish, you can turn any backyard into an entertainment center.
