Power compression is the reduction of sensitivity at the specified power. 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. AES Standard (45 to 450Hz) Program 400Watts.
2. AES Recommended Practice.
3. Thiele - Small Parameters follow a 400 Watt 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.
