I have a very vague idea of what bass crossover is, and I'm not sure how it works. Let's say I have front mains that go down as low as 60Hz, and that I want as much as bass to come from my mains as possible, as opposed to my sub, which I'd like to reserve for below 60Hz tones only. Would I set the bass crossover to 60Hz to accomplish this? If I set the crossover to 100Hz instead, would I hear the same tones from my sub and my mains? That is, would the 60Hz - 100Hz range overlap between my sub and mains? Or would my mains simply start putting out less bass because everything below 100Hz is now being sent to the sub?? Thanks to anyone who clears this up for me!!
My mains start rolling off at 40Hz, but yet, I set the crossover at 80Hz. This does not mean that you are wasting your Large speakers. A crossover has a associated slope for low-pass and high-pass. When you set your subwoofer crossover to 80Hz and if the slope (See crossover spec) says 24dB per octave, it means that the signal is attenuated at 24dB per octave. An octave is a doubling of frequency. The next lower octave to 80Hz is 40Hz. If you are playing at reference levels, your front speakers may be demanded to do say 95dB at 80Hz. A 40Hz then may require the mains to do 71dB at 40Hz. Now that is the tip of the ice berg which I hope is suffice to get you started.
