Selby Acoustics is an Australian audio retailer, not a manufacturer, and it appears to have begun as an eBay business in 2003, founded by Shaun O’Brien. Its heritage is therefore retail-led rather than component-design-led, with later growth into a broader omnichannel operation and showroom presence in Victoria.
The company’s core focus is home theatre and hi-fi accessories, with a catalogue that includes amplifiers and receivers, speakers and speaker accessories, turntables and hi-fi accessories, audio and video cables, connectors, adaptors, mounts, brackets, racks, and other AV hardware. It also sells related smart-home and display-installation products, which places it firmly in the practical system-building end of the audio market.
In market terms, Selby Acoustics sits in the value-to-mid-tier retail segment rather than the high-end or collector space. Its reputation is built on breadth of range, convenience, and customer support for mainstream hi-fi and home cinema buyers, making it a useful destination for accessories, installation parts, and entry-to-mid-level audio components rather than prestige audiophile exclusives.
