So I have a 5.1ch system, just added the sub... by the way, I knew Sunfire subs were tiny, but JESUS this thing is 9.75" Cubed and is dwarfed by my RTi12's lol, and is a lil monster (no SVS, but still!). Anyways, I enjoy listening to music in Extended Stereo (yes, I know, hate me whatever), so I decided to create that mode via the PEQ since I hadn't seen any option for it. I copied the L to SL, R to SR, and moved center to center (stupid and unecessary?), and now the sub... I Copied Right to Sub, and then Low Pass'd it at 40hz. If I understand this correctly, it'll copy my front right channel (which has full range???) and send it to my sub, and then filter out everything above 40hz? THAT is my main question, real quick, I also told JRiver not to do any mixing, and no dolby (I don't have a DAC, just straight from the sound outs to the amp)... is this ok? Considering I want extended stereo, I figured the mixing would mess something up? I DO watch movies, and would LIKE to have 5.1 proper for movies, so I take it I have to switch back to mixing and turn off the PEQ when I want to watch a movie for those results?? Answers to these questions would be greatly appreciated, and I guess its' not really a quick question like I thought... heh, thanks guys/gals!!! I'm holding off playing audio to make sure I don't mess up my sub, so quick answers are also appreciated
