I switched my front left and center speakers, all still played at 75db. I switched them back, but changed the connection going to them (front left on the amp is now going to center speaker, center on amp is going to front left speaker) still at 75dB. Watched House of 1000 corpses last night (yeah, i know, its not lord of the rings!), but the dialogue seemed too quiet still. I cranked up the center all the way possible on my receiver and it to a satisfactory level.

Hopefully i'll have some time to put LOTR back in and see what I think it sounds like now. Also need to get the pink noise out again, see what my center registers at now.
