This is a buyer’s market, and US$18 is an outstanding bargain against the comparable-listing median of US$191 and 25th-percentile price of US$100. Even allowing for this being a small replacement part rather than a complete amplifier, the price is low enough to justify serious interest.
The board is purpose-built for the Sonance Sonarray/SR2-125 system, whose amplifier uses dedicated DSP tuning to balance the array. That makes a working replacement potentially valuable to someone restoring or completing an installation, while its compact, specialized nature explains the limited standalone demand. Confirm that it is the correct revision, undamaged, and actually functional—or at least removable and visually intact—but at US$18, the risk is modest.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Sonance is an American architectural audio brand founded in the early 1980s by Scott Struthers and Geoff Spencer in Southern California. The company emerged from a simple but powerful idea: that high‑fidelity sound should not compromise interior design. In 1982, Sonance introduced the world’s first in‑wall loudspeaker, effectively creating the architectural speaker category and establishing a legacy built on innovation and discretion.
Today, Sonance is best known for in‑wall and in‑ceiling loudspeakers, outdoor audio systems, and multi‑room audio solutions, rather than amplifiers, turntables, DACs, or headphones. Its product range includes residential and commercial speakers, volume controls, and related electronics designed to blend seamlessly into walls, ceilings, and outdoor environments. The brand’s “degrees of invisibility” philosophy emphasizes clean aesthetics, flexible installation, and consistent performance across diverse spaces, from luxury homes to commercial venues.
Sonance occupies a strong position in the mid‑to‑high‑end custom‑installation market, widely recognized and frequently awarded in architectural and outdoor audio. It is a go‑to choice for integrators, architects, and design‑conscious clients who prioritize both performance and visual subtlety, rather than visible hi‑fi hardware.
