JBL continually strives to update and improve existing products, as well as create new ones. The specifications
and details in this and related JBL publications are therefore subject to change without notice.
* The Peak Dynamic Power is measured by recording the highest center-to-peak voltage measured across the output of a resistive load equal to
minimum impedance of the transducer, using a 50Hz sine wave burst, 3 cycles on, 17 cycles off.
