Daniel & Ted Fletcher Invent Airsound
Starting with a mid-side recording, Daniel assembles a speaker box in the studio to reproduce the mid-side recording directly. Ted develops this with analogue processing to allow mid-side stereo playback of any recording. Stereo Airsound is born.
2009
Airsound Launched
In 2009, the first Airsound driven product, the Orbitsound T3 is launched; a small portable speaker which featured mid-side stereo Airsound playback using a dipole sound steering speaker.

Airsound Stereo in Soundbars
The Orbitsound T12 proves incredibly popular, providing a compact footprint yet wide sounding home theatre experience. It becomes the UK’s #1 selling soundbar in 2012 and 2013.
2016
DSP Driven Airsound
The Bar A70 is launched, featuring a more advanced and spatially accurate stereo sound from the first digital Airsound algorithm.
2018
HALO Airsound Invention
Under a new patent, the first HALO Airsound driven product comes to market. The Airsound Dock E30 (pictured with inventor Daniel Fletcher). HALO features a spatial crossover to deliver more powerful bass whilst maintaining a true and wide stereo sound.
