Steinway Lyngdorf is a Danish manufacturer of luxury audio systems founded in 2005 as a partnership between piano maker Steinway & Sons and Danish audio entrepreneur Peter Lyngdorf. The company is headquartered in Skive, Denmark, where its systems are engineered and produced.
The brand's founding project was the Steinway Model D loudspeaker system, developed to meet Steinway & Sons' standards and named after the company's concert grand piano; the flagship system is priced in the hundreds of thousands of dollars. The range now covers floorstanding, in-wall, and on-wall speaker systems together with matching processors and amplification, serving both dedicated two-channel listening and large-scale home theaters.
Steinway Lyngdorf systems are fully digital from source to speaker, using the company's digital amplification technology, and feature RoomPerfect, its proprietary room correction system that adapts sound reproduction to the acoustics of each listening space. Systems are sold as complete, matched chains of electronics and speakers rather than individual components.
The company sells through a global network of authorized dealers and custom installers, with projects spanning private residences, yachts, and screening rooms. Its positioning combines the Steinway & Sons name and finish quality, including polished piano lacquer cabinets, with Danish audio engineering, placing it among the most expensive factory-built home audio systems available.
