W-13 Loudspeaker Parameter Measurement Methods

Chair: David Clarke, DLC Design, USA

Richard Small (Harman/Becker Automotive, USA)
Ryan Mihelich (Harman/Becker Automotive, USA)
Wolfgang Klippel (Klippel GmbH, Germany)
Guido D’Hoogh (Philips Speakersystems, Belgium)

Parameters describe drive-units based on a model, commonly the Thiele-Small model. This model assumes a linear, time invariant drive-unit. This model has proven to work well in predicting speaker system frequency response provided signal amplitude is low. Measured T-S parameters have, to some extent, replaced performance measurements for drive-units. They fail near maximum output of the drive-unit, where, by definition, the drive-unit becomes non-linear. This workshop will discuss drive-unit behavior near maximum output.
