My receiver is from 2002 or so. I have a Onkyo 875 on the way. This is where I first heard of the problem. Their review of the 805 states that different crossovers are bad and that even the Onkyo does not process it completely right.

"The crossover frequency can be set independently for each pair of speakers, the soundtrack's bass can be sent to both the main speakers and a subwoofer ("Double Bass" they call it), and the LFE channel can be low-passed at a different frequency from the rest of the bass being sent to the subwoofer . . . all of which we vehemently maintain are bad ideas, and we back that up in our essay on the subject: Miscellaneous Ramblings on Sub Crossover Frequencies. It is no fault to the product's performance, but it questions Onkyo's marketing decision to give the people what they think they want even though it may mean they hang themselves with it (unawares as they may be)."

This whole issue has me so confused...
