The Epicenter of Your Outdoor Sound Experience™
The Terra AC.SUBe is a powerful, weather proof partial burial subwoofer that provides a real foundation for your outdoor musical enjoyment. Its water-tight rotationally molded Polyethylene enclosure is completely impervious to the elements and since it’s totally sealed there’s no concern about insects or small animals getting side and doing damage. The internal custom-built cast aluminum 12-inch woofer is a study in high performance, low distortion and all weather reliability. Its ACAD™ (Anodized-Ceramic Aluminum Diaphragm) cone is stiff, responsive and impervious to the elements. The driver’s motor structure includes a large ceramic alloy magnet and a vented 2-inch aluminum edge wound voice coil. Its surround is a half-roll rubber composite that’s also impervious to the elements including salt spray and chlorine mist (as is the rest of the system). The compact AC.SUBe is designed to be partially buried 2/3 of the way into the ground leaving its mushroom shaped top exposed. It’s available in green or black and the color is imbedded throughout the polyethylene material for ultimate durability. The AC.SUBe is conservatively rated to deliver 26 to 115Hz (+/- 3dB) of powerful, authoritative bass in the backyard, the garden or around the pool. Of course, as a passive design the AC.SUBe isn’t intended to be used alone. Terra offers a custom programmed Crown™ CDi 1000 dual channel power amplifier that’s been set up to maximize the sub’s performance and integrate its output with Terra’s award winning all-climate speakers. The AC.SUBe makes for a spectacular outdoor music system, easily on par with traditional high quality indoor audio reproduction.
