Thespecifications 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 ofa resistive load equal to minimum impedance of the transducer, using a 50Hz sine wave burst, 3 cycles on, 17 cycles off.BALBOA series SUB101
