About the SD502
Usher Audio SD-502 is a floorstanding, three-way bass-reflex loudspeaker designed for precise time alignment and high-resolution playback. It uses Usher’s 1.25-inch DMD diamond-diaphragm tweeter, a dedicated midrange driver, and dual 5.5-inch bass drivers to improve dispersion, reduce distortion, and strengthen low-frequency performance. The cabinet is heavily braced and the crossover uses air-core inductors, high-quality capacitors, and oxygen-free copper wiring. The model is listed by dealers at a retail price of 69,000 NOK, while broader availability appears limited, suggesting it is not an actively current mainstream model.
