We are going to use TAS5805M in PBTL mode for subwoofer application.
We will be using the internal linkwitz-rilley digital filter to set the cut off frequency around 100~120Hz.
However, as the subwoofer will be 1.5~2m away from the TAS5805M, what do you suggest to reduce EMI?
1. Should/can we a need an external analog LPF to reduce EMI from the PWM signal?
2. If yes, what is the recommended component values for this analog LPF?
