[QUOTE="gbyleveldt, post: 69603, member: 122"] Ah, so you want to tame that full ranger then. Unfortunately it's impossible to add a notch to the system response if you don't know what the impedance of the system is at the frequency that you after. You must also be careful when doing that, as you could potentially create a very low impedance at that point for the amplifier to drive. If you have a signal generator, AC millivolt meter (or oscilloscope) and lowish ohm series resistor you can measure the impedance of the driver at that frequency (you essentially creating a resistive divider). But this is a little painfull... [/QUOTE]
