* The Peak Dynamic Power is measured by recording the highest peak-to-center voltage produced by the power
amplifier with its limiters disabled, across the output of a resistive load equal to minimum impedance of the
transducer, using a 50Hz sine waveburst, 3 cycles on, 17 cycles off.
Occasional refinements may be made to existing products without notice but will always meet or exceed original
specifications unless otherwise stated
