Generally I don't think I get very discreet effects when watching DVDs (5.1 Dolby) and I generally use Dolby Pro Logic IIx movie mode.

The speakers are custom made for me by Madisound here in Madison Wisconsin. I use a DBX electronic x-over and bi-amp the fronts. The two subs are 18" Electrovoice drivers in 13.5 cubic foot vented enclosures, flat power to 24hz. The front and rear speakers are 12" in two and a half cubic foot inclosures crossed over at 380hz to a pair of 6.5" mids which are crossed over passively to a 3/4" concave kevlar tweeter at 3.5khz. For the center I'm using a Electrovoice 8" two-way studio monitor and the side surrounds are Descante 5.5" two-ways. I'm crossing the Outlaw over at 80hz for the fronts, 100hz for the center, 60hz for the rears and 120hz for the side surrounds. Power is Adcom 555a's for the front and subs, Dynaco (can you believe it) 150 strapped for mono for the center, Adcom 545 for the side surrounds and BK ST140 for the rears. The room is 23' by 13' with a sloped ceiling going from 7.5ft to 8.5ft. The projector is a Sony HS20 and the screen is 80" 16:9.
