Axiom Home Page Forums General Discussion Home Theater Advanced crossover settings

Yeah I know about rolling off frequencies. I'm just saying what I read somewhere in my history of researching receivers, was that using separate x over settings resulted in the bass from the higher x-over speakers not being redirected to the sub. It said you shouldn't have too much of a difference between your highest and lowest x-overs. This statement has confused me, as it seems to defeat the purpose of having separate cross overs (i.e running almost full range mains while having surrounds x-ed over much higher). Hopefully what i read was wrong and is complete b.s. and was based on poorly translating Japanese or reading a Denon manual.
