TDA2030A
LINEAR INTEGRATED CIRCUIT
the tweeter can be optimized in the design phase taking in account the loudspeaker efficiency and impedance
(RL=4Ω to 8Ω).
It is quite common that midrange and tweeter speakers have an efficiency 3dB higher than woofers.

MUSICAL INSTRUMENTS AMPLIFIERS
Another important field of application for active system 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 reliable. A typical example (see Fig. 4) consist of four amplifiers each driving a low-cost, 12 inch
loudspeaker. This application can supply 80 to 160W rms.
