The side walls of the CH-3 are straight, forming a constant 90o pattern in the horizontal plane. Thus, the on-axis response tends to track the driver's power response. Not completely, because the vertical pattern isn't CD. But enough that top octave compensation is necessary.

Look through your manuals because I think your crossover has an option for CD equalization. That's what you want. If not, you'll need to find another way to add EQ.
