Higher power ratings do not necessarily give a proportionate increase in SPL therefore the maximum SPL of the driver may significantly exceed that of other manufacturers with high power ratings. 1. A.E.S. Standard (60 to 100 Hz). 2. A.E.S. Recommended Practice. 3. Thiele - Small Parameters follow a 300 Watt A.E.S. preconditioning period. Please note that frequency response measurements are supplied for comparison purposes only and are not a measure of the low frequency performance which may be achievable in a fully optimised system.
