2.2.2 Woofer-Tweeter Implementation Recommendations

On a Woofer-Tweeter application the power and frequency content can be differentiated between TAS2120 and TAS2320.

For example, TAS2120 is used to drive the Tweeter, using PPC3 the digital high-pass filter can be set to 1kHz and the gain to the maximum 21dBV. TAS2320 is used to drive the Woofer, the high-pass filter can be set to default 2Hz and the gain is also set to maximum 21dBV.

The gain for each amplifier can be fine tuned based on the sensitivity of each speaker.
