Redirected bass -- and ALSO the LFE channel.
I found several white papers, one co-authored by Pioneer engineers, about the whole issue of bass mgmt. They are technical, one by Dolby, and one by the Pioneer engineers, and I want to browse them before drawing final conclusions, which I can't do now. But if what I read in the Pioneer paper is stated correctly, then I believe your concerns will be alleviated - that Pioneer is in fact doing proper LFE/LPF and not losing any frequencies.
what makes it confusing is that I think Pioneer's global Xover - bass mgmt does doesn't clip any freq's but does pass the whole 120 hz bandwidth for LFE but its not apparent to the user (unlike Denon, Onkyo, which has a separate setting for it). the user only sees "half" the equation.
give me a day or so to make sure I'm right and get in a position to post the papers with relevant quotes. also a thread that discusses this.
the phrasing in the manual has been around forever (exact same wording as in 59TXi manual) and does not exactly explain it very well.
