Constructed and tested to withstand the harshest outdoor conditions, The ATON™ Storm Series Outdoor Speakers are guaranteed to provide years of reliable outdoor use. Each model’s all-weather cabinet design effectively shields the speaker from the elements and makes the speaker ideal for any outdoor application.

But the test of a great outdoor speaker is more than its durability. It has to deliver high quality sound in an environment very different from indoor applications. As a result, all Storm Series Outdoor Speakers are voiced to provide adequate sound pressure levels and deliver big, indoor-quality sound even in outdoor, open-air conditions.


All models feature 1" waveguide tweeters for controlled hi-frequency dispersion, excellent off-axis frequency response, high power handling, a unique bass reflex acoustic design, and custom Q crossovers and driver materials that provide the best price/performance ratio in the industry.


From the pool to the patio, in saunas or on a boat, each model can be easily mounted horizontally or vertically onto walls using the included custom C brackets. Once mounted, the speaker can be pivoted (up to 180˚) to direct the sound to the intended location. And all models perform equally well indoors and can be used for distributed audio and surround sound applications where in-wall, ceiling or large box speakers are not desired or practical.
