I have my home theatre sounding pretty good and speaker locations are in pretty much ideal locations.....lf and rf equidistant from center channel and seating position to lf and rf creates an equilateral triange. Center Channel is slightly above ear level (on a shelf above fireplace and tv is about that). Problem is I have a very loud room (hardwood floors with little furniture for now...HT took precedence..hehe) and was wondering what the treble/bass settings should be (low, zero, high) to enhance voices. I have the system setup using SPL and AVIA so we don't need to get into all that....just wondering if messing with Bass/Treble levels could have an affect on dialogue. I can hear 90% of dialogue, but still have a little trouble occasionally.....have big cushy furniture on order which will lead to a large area rug which I am sure will soften the room up significantly...also plan on putting two large canvasas behind the couch on the currently blank wall which I am sure will help suck of some of the reflections.....and the wife thinks all this is for just for decorations....hehe..
