This is very much a buyer’s market: US$15 is a strong bargain, sitting far below the comparable-listing median of US$195 and even under the US$100 25th-percentile mark. For a small, model-specific replacement part, that is excellent value if it is genuinely the complete pair of controls.
These are the physical selectors used to access the SR 2-125’s built-in DSP presets, which are central to matching Sonance outdoor speakers and installation environments. They are not a universal upgrade, but they can restore an otherwise incomplete amplifier and may be surprisingly difficult to source separately. Confirm that both knobs and the associated bank/selection hardware are included, that the shafts and markings are intact, and that they fit your amplifier revision; at US$15, those checks are worthwhile rather than deal-breaking.
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.
