2005 Perth CABIN AutoSalon Results: SPL = 166.2dB Term-LAB Frequency = 20Hz Battery Voltage = 9.55VDC Amplifier Current Draw = 982 Amps Amplifier Power Input = 9379 Watts RMS Amplifier Power Output = 6922 Watts RMS Cone Excursion = 125mm peak to peak Amplifier Full Power Test: 20,000Watts RMS for 55milliseconds @ 50Hz 13,000Watts RMS for 15 Seconds @ 50Hz
As you can see, our battery power supply is insufficient right now. 166.2dB is not bad for half amplifier output power but !! We can now reinforce the locking system on the cockpit, it was flexing over 3mm !!
