* Power compression is the reduction of sensitivity at the specied power. Higher power ratings do not necessarily
give a proportionate increase in SPL therefore the maximum SPL of the driver may signicantly exceed that of other
manufacturers with high power ratings.
** Distortion is measured at 10% of the rated power (A.E.S. Standard).
1. A.E.S. Standard (50 to 500 Hz). Program 800 Watts.
2. A.E.S. Recommended Practice.
3. Thiele - Small Parameters follow a 400 Watt preconditioning period veried by Klippel LSI measurement.
4. 2.83V. Half space response measured in a 975 Litre sealed enclosure.
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.
