[QUOTE="n2audio, post: 8673759, member: 540940"] Logically, it seems like it should work, but when you choose a speaker level cap you calculate the cap's value using the impedance of the load. With amp inputs typically being several thousand ohms I'm not sure this would work. I will try to come up with a definitive answer... After consulting an expert -- apparently impedance on speaker level inputs can vary drastically, so unless you have that value from the mfg there's no way you could size your filter. DC resistance measurement wouldn't be much help because the inputs will not behave like a speaker. [/QUOTE]
