Authoritative Subterranean Bass for Expansive Outdoor Landscapes
The OSD Eclipse 12-inch In-Ground Subwoofer solves the biggest challenge in outdoor audio: generating deep, impactful bass in open-air environments where there are no walls to reflect sound. By burying the high-capacity acoustic chamber discreetly underground and venting bass through an omni-directional top port, the Eclipse 12 produces visceral low frequencies that blanket outdoor living spaces without cluttering visual landscape aesthetics.
Massive 12-Inch Burial-Rated Bass Driver
At the heart of the Eclipse 12 is a heavy-duty 12-inch polypropylene woofer with an oversized voice coil and weather-treated surround engineered specifically for subterranean acoustic loading. Capable of handling up to 800 watts peak (400W RMS) in 4-ohm mode or 200 watts on commercial 70V lines, this driver delivers tight, punchy low-end impact down to 30Hz with effortless dynamics exceeding 100dB sound pressure levels.
360-Degree Omni-Directional Sound Field
The vented above-ground hood disperses bass evenly in a full 360-degree horizontal radius. Whether you are gathered around the pool, dining on the patio, or walking through garden pathways, the low frequencies integrate smoothly with landscape satellite speakers, creating an immersive, full-fidelity soundstage across large residential estates and commercial outdoor venues.
Built-In 3000K Warm White LED Landscape Lighting
Combining visual elegance with acoustic performance, the Eclipse 12 features an integrated 13W LED lighting ring powered by standard 12V DC landscape lighting transformers. The 3000K warm white glow illuminates surrounding foliage and garden paths while demarcating the subwoofer hood at night, operating on independent low-voltage wiring compatible with smart landscape timers.
IP65 UV-Resistant LLDPE Burial Enclosure
Built to withstand constant soil moisture, freeze-thaw cycles, fertilizers, and ground pressure, the main enclosure is rotational molded from Linear Low-Density Polyethylene (LLDPE). Rated IP65 for complete water and dust resistance, the subterranean chamber remains impervious to environmental elements year after year.
