Axiom Home Page Forums General Discussion Technical Questions Denon Audessey Setup - Subwoofer Distance

Hello all.
So I finally got my Denon AVR 2807 in and plugged up.
I did the auto setup procedure with the MIC at 6 locations.
While everything seems ok, the frequencies it selected were kind of strange. However, I left them alone and it seems fine.

My real concern is the distance it detected on my subwoofer. 25ft. My sub is about 8ft from the listening positions.
The manual says to set the sub crossover to its highest and to set the volume half way. Can someone please guide me here.... Has anyone done this on a denon?

Second and last question...what does denon consider reference volume? In other words if I want to manually set my speaker distances and levels then what volume level should I use to get the reference 70db?

Thanks all.
