I was just posting a response on another thread about cascading crossovers -- on the PSW10, in this case, the documentation from polk says set the crossover as high as it will go, which will be a "virtual" LFE input, and then adjust the crossover on the AVR to the desired frequency.

The question is, is this every bit as good as an actual LFE input? Is there still some cascading effect or some other undesirable issues caused by the lack of a "true" LFE input?
