[Elecraft] filter settings and hearing

[John Wiener]

Hi,

I have an odd question for the group.

As hams age, we begin to notice that our hearing decreases in  
sensitivity in the higher registers.
In a K2, one can easily change the Spot audio frequency downward to  
accommodate this process.

Is it straightforward to adjust the filters so their center  
frequencies are lower, too?

Or am I way off the charts on this one?
