Even after this thread I'm still not sure what is meant in this particular case by "cascading" filters. Does that simply mean "put one filter after another"?
Cascading filters is a common enough term in popular audio literature -- it's what happens when you have bass management happening in your AVR (applying a low pass filter with a crossover frequency of X hz to the signal, and directing the output to the subwoofer channel) AND your subwoofer applies its own lowpass filter too. Typically one is advised to turn off the LPF of the sub, or set the sub's crossover frequency to maximum (which hopefully is well above the crossover frequency used for the AVR's LPF).
