    Hi guys! I need some advice and help tweaking my system. I primarily use this as a HT and videogame setup. I have the following equipment:

    Reciever - Denon 2802
    Sub - Velodyne CHT 10 28hz - 120hz (connected to sub out on Denon)
    Fronts - B&W CWM 650 50Hz - 20kHz (in-wall speakers)
    Center - B&W CWM Cinema 55Hz - 20kHz (in-wall speaker)
    Surrounds - B&W CCM 65 - 50Hz - 20kHz (in-ceiling speakers)

    I've tried to tweaked this as much as I could using the Avid DVD and an SPL meter. Now I know since I have in-wall speakers this may change some acoustics but I had to get them for the wife factor. My front and surround speakers are two way 6.5 inch cones with a 1 inch tweeter except and my center has two 5 inch cones and a 1 inch tweeter.

    1) I wanted to know what is the best Crossover frequency response to set my Denon to (80, 100, 120)? I've contacted both B&W and Velodyne and they recommend 80hz but wouldn't it be better to send all my bass and mid-bass to the sub?

    2) Do need to set the Phase Adjustment at 0 or 180 ( I wasnt able to figure this out using the AVID DVD).

    3) How should I adjust the channel level on the sub? Should I set the Denon SW Channel to 0db (range from -12db to +12db) and adjust the volume knob on the Velodyne during the Avid set up?

    Thanks for your help in advance

    1) Most people recommend setting the speakers to 80 if you have that option.

    2) Phase adj doesn't seem to make a difference for most people.

    3) I would set your sw channel at -6 and your Subamp volume at 1/2 and play with it from there using the avai setup.
