At €200, this asking price sits just above the median of €170 for comparable used Sonance Symphony speakers but remains well below the 75th percentile of €306, making it a fair and solid deal rather than a bargain or an ambitious overprice. The 25th percentile is €87, so this is not a deep discount, yet the price reflects a clean listing in a healthy market where values typically range from €87 to €306.
Sonance Symphony speakers like the 623TR are well-regarded for their carbon fiber woofers and silk dome tweeters, delivering balanced sound ideal for both movie soundtracks and classical music. Their bezel-less grilles and magnetic retention make them a premium choice for in-ceiling installations, and the fact that this unit is listed without known condition issues adds meaningful upside. With no red flags on failure points or missing accessories, this is a genuine buying opportunity for an enthusiast seeking reliable, high-fidelity audio at a fair price.

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.
