The sandstone ROCKSOLID 2-SS Direct-Drive In-Ground Speaker from Solid Drive comes in a pair and each incorporates two Solid Drive transducers mated to a polyurethane enclosure to deliver consistent omnidirectional coverage pattern. For installations requiring high-performance sound in a durable speaker design, the ROCKSOLID 2-SS incorporates a 70.7 / 100V transformer with a maximum SPL of 86.0 dB.
The Solid Drive transducer utilizes patent-pending dual-voice coil technology in an aluminum enclosure to transfer acoustic energy directly to the enclosure. By incorporating symmetrically opposed neodymium magnets the ROCKSOLID 2-SS achieves acoustic uniformity throughout the listening space. The speaker features a custom, built-in equalizer (notch filter) tailored for a smooth frequency response.
