The Carlsson Loudspeaker was designed in 1974 by Stig Carlsson, and was known for its warm, relaxed sound. To capture the look and feel of the original speaker, Teenage Engineering drew from the original technical drawings, including the precise dimensions, volume, white cabinet, and black grille.

Teenage Engineering renamed the speaker OD-11, but maintained its primary focus—it is designed for music lovers. The team thoughtfully re-engineered Carlsson’s legendary loudspeaker by adding a built-in computer, 100-watt amplifier, and the latest wifi technology, allowing the speaker to play music from any device in wireless stereo. It was crucial to the team that the speaker maintain what made the Carlsson Loudspeaker stand out in the 70s—the sound it produced. Although it’s often challenging to make digital music sound authentic, Teenage Engineering was able to master this, maintaining the original ortho directional speaker principle.

The OD-11 is compatible with Apple Airplay, Windows, and can stream from music services like Spotify. The speaker can be used with the Ortho Remote, which is a sleek, wireless volume knob with click functions so users can play, skip, and return to the previous song without having to get up. Both the speaker and remote can be used with the Orthoplay App, which communicates with other Teenage Engineering devices to create room-to-room sound.
