I didn't pay attention to the values of the components. Jim and Akhilesh were looking at the circuit trying to figure out what it was, so I went to look at it. There was a coil and resistor in parallel, and this network was in series with the driver. I would assume that was a BSC network, although I didn't liook at the values to know where it cut in or by how much. After the BSC filter, there was a series cap, coil and resistor connected in parallel across the driver, forming a notch filter with resistance to set the Q of the notch. Here again, I didn't check the values but assumed it was probably there to tame a peak in the overtone region. Maybe Jim can chime in, look at the component values and let us know.
