I am a frequent poster to the dedicated NAD T775/T785 thread, but I decided to create a new one since this is not specifically a NAD receiver issue but could be a general Audyssey or a speaker issue.
My HT consists of
NAD T775HD receiver with the latest firmware. It has Audyssey MultiEQ XT with 8 position support.
Speakers: Klipsch RF-5 floor standers for the mains (these are advertised as 37Hz-20k Hz). Klipsch RC-7 Center. Klipsch RS-35 surrounds, and Insignia bookshelves for the surround backs. Also have a bottom firing Elemental Designs A300 for Sub.
When I run Audyssey on my NAD, it reports the crossover freq for the mains as 180Hz, 50Hz for the center, 60Hz for the surrounds and 60Hz for the rears. The mains are supposed to be the most capable of my speakers. What's wrong. Is the Audyssey software not hearing it properly or could my speakers be going bad. They are from 2004. Can a bad crossover do this? Could my room geometry do this. I have tried moving my speakers around a little bit, but the best crossover I came across was 140Hz. I wish I had another receiver with Audyssey I could run with to see if it is a receiver issue or a speaker issue. The funny thing is, I took my Insignia and wired them up as mains, and the NAD reported 60Hz for it. So it cannot be entirely NAD's fault. Weird.
