Forgive me if I do not have the correct place to begin this thread; if so, administrator please re route it to the correct area... I own an Onkyo TX-SR600 receiver which powers a Polk 5.1 speaker array, including a 10" powered sub (Polk); the source, amongst other units, is a Panasonic DVD-RA60 DVD audio/video deck. While calibrated to my liking, it seems whenever I watch Dolby Digital encoded DVD soundtracks, I need to crank my Onkyo up to at least "50" on the volume display to really begin getting "immersed" in the film I'm watching; some DVDs, if it doesnt carry that great of a soundtrack (like some "Dolby Surround" discs I own which decode to Pro Logic II) require me to crank the volume WAY beyond that number, and it just seems illogical to me that it would be necessary to do this because the receiver only goes up to a maximum of 99 or 100 I think on the display....50 is already "half way there" and as I said, sometimes I need to go into the 60s in order to get the soundtrack "really rocking"....with most DTS discs, I do not need to do this---50 seems plenty on the volume, ESPECIALLY if it is a soundtrack like Saving Private Ryan, Black Hawk Down, etc. Then, there is the issue of the sound "filling the room"...I am in a rather small listening area, in a studio apartment, and yet STILL when I crank certain films up, and when I have company over, either a friend or my girlfriend, and we are sitting on the couch (me in the sweet spot of course), it seems that I can easily conduct a conversation over the audio coming from my surround system, especially when just dialogue is coming from the center speaker. Is this normal? Sure, when bullets and explosions begin ripping from an aggressive soundtrack like Saving Private Ryan, its harder to talk over, but for the most part, with most soundtracks, it seems like it is easy to talk over the movie that is playing through my system...is this a normal issue with home theater? I already have my center channel cranked 3 dB's higher than all my other channels to compensate, but still, with dialogue, the sound doesnt seem to "fill the room" that aggressively unless I begin turning that Onkyo WAY up...do any other Onkyo owners experience the same thing? Is it okay to need to crank our receivers to get really room-shaking sound out of them --- even if we feel we are approaching maximum output from them? As I said, Dolby Digital soundtracks usually begin to heat up around "50" on the volume display of my TX-SR600; below this, unless its late at night, the DVD soundtrack doesnt have a bone-crunching impact --- especially with dialogue. DTS soundtracks dont usually require that much volume power, but recently, I noticed on my Spider Man 2 Superbit DTS track that I needed to crank that soundtrack into the "40"'s on the display in order to get it to open up sufficiently. I should probably also mention that my Onkyo's "IntelliVolume" settings are up to "+10" across the board, so I know the input levels arent turned down which could have been causing the problem; I know it cannot be the IntelliVolumes. Any thoughts?
