US$185 is a strong deal: it sits well below the comparable-listing median of US$199 and comfortably under the US$105–US$319 middle-market spread, though not quite at the bargain-level 25th percentile. For a working unit, that is attractive money for a serious multiroom amplifier.
The 12-50 is useful precisely because it delivers 12 channels at 50 watts each, with 4-ohm capability, bridgeable pairs for 100 watts, and efficient, fanless Class-D operation. It is a practical choice for distributed audio or several stereo zones rather than a conventional two-channel setup. Because the condition is unspecified, confirm that all channels work, the terminal blocks and rack ears are present, and the unit matches your mains voltage; otherwise, this looks like a worthwhile buy rather than a risky stretch.
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.
