Web15 Dec 2007 · Thiele / Small (T/S) Speaker Parameters. This is a short definition list of the Thiele / Small (T/S) speaker parameters. These are electromechanical parameters that can be used to define how a loudspeaker driver performs. They are named after A. N. Thiele and Richard H. Small who pioneered this line of analysis for loudspeakers. Web28 Jan 2013 · The Thiele/Small parameters is a set of data that tells you everything about the physical and electrical properties of a driver. If we were to think of this as food, the Thiele/Small parameters would be the ingredients to a cake (driver). Using the ingredients, we can calculate how they come together and would taste, or in a driver’s case, sound.
