Another important field of application for active systems is music.
In this area the use of several medium power amplifiers is more convenient than a single
high-power amplifier, and it is also more realiable. A typical example (see Figure 24)
consists of four amplifiers each driving a low-cost, 12-inch loudspeaker. This application can
supply 80 to 160 WRMS.
