There is no reason to have both the 2700 and 2800 Hz filters. 
You will not be able to detect any difference between the two.

The 2700 Hz filter.

If you like 2200 Hz in your Icom for SSB and 400 Hz for RTTY, 
you would be better served to add the KFL3A-2.1K (instead of 
the KFL3A-2.8K) for SSB and the KFL3A-400 for CW/RTTY
