Being unhappy with the current bass management and associated crossovers in receivers, I wanted to clarify that I understood how receiver crossovers worked. I understand crossovers in speakers, but I wanted to make sure that understood the way they work in receivers.
In the case of both HIGH PASS and LOW PASS, does a crossover entail rolling off the frequencies BEFORE the "center frequency of 100 hz"?
For example, we'll discuss the crossover between the front Left and Right main speakers and the Subwoofer.
If the crossover between the subwoofer and the front main speakers is 100 hz, does that mean that the signal sent to the subwoofer has low frequencies are rolled off starting at say 80 hz and the signal sent to the front main speakers is rolled off at say 120 hz, each which whatever respective slope is applied?
What I mean is, the crossovers in receivers are not steep brick walls, but more likely a shallow 6 dB per octave blending with the frequencies sent to each dropping off well before that crossover frequency? For instance, at the crossover frequency, the sound is being reproduced by both subwoofer and mains somewhat equally?
