I'm trying to compare these piezos to the KSN1038 but I'm going blind trying to read the scale on the freq response graph--I swear that's why I'm going blind, it's not because of the "other thing" ;-)

There seems to be 5 minor divisions per major division.
In between 4k and 5k Hz, the response rises one minor div, is that ~3db?
There's a trough after 10k to about 15k Hz, is that ~3dB?

Thanks,
Jeff
