Figure 19: Frequency Response

As shown in Figure 19, the R-C passive network

for low-pass and High-pass give a cut with a

slope of 12dB/octave

A further advantage of this application is that con-

necting each speaker direcly to its amplifier, the

musical signal is not modified by the variations of

the impedance of the crossover over frequency.

The subwoofer is designed for obtaining high

sound pressure level with low distortion without

stereo effect.

In the application of figure 18, the subwoofer

plays the 20 to 300 Hz frequency range, while the

remaining 300 Hz to 20KHz are sent to two sepa-

rate channels with stereo effect.

The multiway

system makes

use of

three

TDA2052, one for driving the subwoofer with

POUT higher than 40W (THD = 10%), 28W undis-

torted (THD = 0.01%), while the others two

TDA2052 are used for driving the mid/high fre-

quency speakers of L/R channels, delivering

POUT = 25W (THD = 10%) and 20W @ THD =

0.01%
