The OSD Audio LS3 Bronze is a pair of in-ground landscape speakers built for outdoor use. Each speaker handles up to 60 watts peak power and 30 watts RMS, with a 4-ohm impedance that matches many home amplifiers. The 3-inch full-range driver provides a frequency response from 80 Hz to 20 kHz, covering vocals and instrumental details. The bronze finish, molded into the polymer enclosure, not only adds a natural look but also resists fading and cracking from UV exposure. The compact design allows the speaker to be installed flush with the ground surface, minimizing obstruction. Weather resistance is a core feature.

The sealed enclosure protects the internal components from moisture, dust, and soil. The woofer cone is treated with a waterproof coating, and the grille is made of perforated aluminum to prevent rust. Gold-plated spring-loaded terminals ensure reliable connection even in damp conditions. The housing withstands temperatures from -20°F to 140°F, allowing year-round use in most climates. The speaker’s low-profile cap prevents water pooling and is sturdy enough to withstand occasional foot traffic.

Audio performance is tailored for open spaces. The LS3 achieves a sensitivity of 89 dB, enabling modest amplifiers to drive them to adequate volume for background music or announcements. The stereo pair creates a wide soundstage, enhancing the listening experience in gardens, patios, or along walkways. While not designed for high-fidelity critical listening, the speakers produce natural sound reproduction with minimal coloration. Distortion remains low at typical listening levels, making them suitable for ambient audio.

Installation is user-friendly. The tapered housing fits into a pre-excavated hole, and the attached 90-degree binding posts allow easy wiring. A ground stake is included to secure the speaker in place. Multiple LS3 speakers can be daisy-chained or paralleled, depending on the amplifier’s impedance rating. The included mounting template helps achieve consistent spacing.

The overall process requires basic tools and can be completed in under an hour. At just $12.78 per pair, the LS3 Bronze speakers offer exceptional value for outdoor audio projects. The combination of rugged construction, weatherproof design, and acceptable sound quality makes them an economical choice for homeowners, event planners, and contractors. They are ideal for those seeking to add distributed audio to a landscape without the cost of premium systems. The pair is a practical investment for anyone prioritizing durability and affordability.
