Re: Death to... test what you think you know
Jay,
I'm not sure where you are going with your conclusion.
Years ago there was a "death to 100" thread about killing everything below 100 Hz on monitor EQ, which on some EQ types also happens to kill frequencies well above 100 Hz.
If one wants to combine a LF signal with the HF signal (in which case phase response in the crossover region is important), the only reason why you would kill the LF on an EQ would be if the sub output was set way too hot and you had no access to the crossover, in which case you are stuck with the lesser of two evils, kill it on the mains EQ, or every channel.
If your goal is removing as much LF from a signal, stacking filters will aid that goal, and the LF phase response of a signal that is attenuated 24 or more dB is of no consequence.
