Abstract:
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.
