This chair concept was designed for a Designboom- international design competition in 2005, winning an "honorable mention". The chair prototyped with a group of Mechanical Engineering Technology students at SAIT in 2010.
"The intent was to design a chair that was extremely loud, and would generate some serious attention. Adding the sound element to the task of designing a chair took this prototype to completely new level". Subsonic has been extensively published in magazines and websites around the world".
