THE ACTIVE SERVO TECHNOLOGY SPEAKER SYSTEM A dynamic speaker electric equivalent circuit shows a direct connection between the electrical resistance of the voice coil and the notional impedance. “Notional impedance” is impedance which arises due to the government of the speaker voice coll. Proportionally more voltage is generated the faster the voice coll moves. Generally, speakers use a constant voltage drive.
The Active Servo Technology Speaker Stern allows you to obtain optimum performance from Yamaha Active Servo Processing Speakers by driving them with an Active Servo Processing Amplifier,which is specially designed o extract their full sonic potential. In order to do this properly, it would normally be necessary to use a different Active Servo Processing Amplifier possessing slightly different characteristics for each different Active Servo Processing Speaker model.
