Has anyone studied the potential benefit of post-amplifier passive filtering on an active crossover design in order to reduce reproduced distortion?
I know it's common to add a HPF to protect the tweeter, but I'm thinking about e.g. a passive low pass filter on mid/sub to reduce amplifier created harmonics that are above the desired range, but still within the reproducible range of the driver. Obviously it would need to be high enough to not mess up the desired signal as shaped by the DSP.
I hope that what I've said is understandable!
PS I'm well aware that with the best amps this is probably irrelevant, but 6 channels of Purifi isn't within current toy budget
Thanks for any input
