<b>Attention:</b><br>
Although it might be tempting to assign low frequency filters only to the subwoofer channel, this might not lead to the expected results. Many audio systems apply bass redirection after Equalizer APO has processed the signal, so filters applied to the subwoofer channel won't be effective for redirected sound. Furthermore, as crossover filters only gradually fade in, the low frequency audio might be played over multiple speakers, not just the subwoofer, reducing the effectivity of subwoofer-only filters. Therefore, to avoid these problems, it's recommended to <b>apply low frequency filters to all channels</b>.
