(Subwoofer)
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%
