A careful re-engineering of the original OD-11, designed in 1974 by Swedish sound pioneer Stig Carlsson and revived by Teenage Engineering using the exact dimensions and woven-steel-mesh grille of the 1974 unit. Carlsson's ortho-directional principle disperses sound omnidirectionally rather than aiming it at a single listening spot, so the speaker fills a room evenly rather than beaming at one seat.

A 100-watt Class-D amplifier and built-in computer handle Wi-Fi streaming directly, supporting AirPlay 2, Spotify Connect, and Bluetooth, with two units pairable wirelessly for true stereo. The Orthoplay app and an optional wireless Ortho Remote handle playback control without ever touching a phone screen if you don't want to.
