I don't know which specific models of filters you have, but I can tell you 
that in many cases filters differ in the number of "poles" they implement. 
An example being replacing the 4 pole 2.4 khz filter in some ten tec models 
with an 8 pole aftermarket filter.  It gives you sharper, and deeper, 
skirts, without much insertion loss.  The result ?  In the heat of battle, 
with strong signals climbing in very close to you, the deeper skirts will 
allow you to operate better through a qrm rich environment.  Otherwise, you 
will notice little change.  If thats the kind of filters you have, it would 
explain their purpose.
