The High Z element will require a high voltage low current drive. To control the frequency response we must adjust the coupling caps and the load resistance. The high R high C circuit gives good low frequency response but drops off on the high end.

Lowering the load resistance flattens the response.

Lower coupling caps cause the low end response to drop off. This will make a 'tinny' sound. | | | | | | | | | | | | | | | | |
