Hi I upgraded to a Onkyo TX-NR3009 which features Audyssey's fabulous XT32 from a Onkyo TX-SR805. I've been reading this thread, there are some that say to raise the XOs 80hz, but I've also read if you have XT32 to leave your XOs where they are.
I'm currently running a 7.1 PSB Image system, a pair of T45 towers, C40 center, and 4 B15 bookshelf for surrounds. After running Audyssey, my receiver has set my towers at 40hz, my center at 60hz and my surrounds at 50hz. My LFE is set to 120hz. All settings are within the speakers anechoic chamber 3db specs. Should I still raise my XOs to 80hz? If so what benefit would I get? And what's the point of getting towers then if you only need a speaker to go to 80hz?
