The filters don't need to be matched in bandwidth but they do need to have the same frequency offset to avoid possible "beat note" problems between the two (main/sub) synthesizers.
I didn't bother to pay the extra 60 bucks to frequency-match the 2.7 kHz in the KRX3 with the old one in the main receiver. The new one came in 100 Hz different than the old one, so I just split the difference and entered the same offset for both. A 50 Hz error is not significant in a 2.7 kHz filter.
