This is an older sub amp, so timing matters mainly in the usual way: you want one that’s been fully tested, because replacement support and recap-level age issues are the real variables here. At US$145, the asking price sits a little below the US$161 median and well under the US$350 75th percentile, so it reads as a solid buy rather than an aggressive ask.
For a subwoofer amplifier, the value is in clean output, reliable standby/trigger behavior, and enough current to keep bass tight without strain, and this one’s fully tested status is the big positive. Free shipping helps the deal further, and at this price I’d view it as a worthwhile pickup if the photos show a clean faceplate and the test notes cover both channels/outputs and basic controls.

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.
