Hello everyone, I have a onkyo tx-sr606 home theater that I'm trying to setup correctly. It's a 7.1 ht. I used the auto calibration method 3 times in a row (I've been told that running it more then once will make the calibration better). I tried the setup for about 3 weeks and it's ok, but when watching tv shows, I have to crank the volume to 50-55 (where starting at 45, there isn't a big difference between the sound volume) where 75 is the max. I saw there is a crossover settings for all channels. I tried understanding them and I want to be sure I'm doing good on that. Here is the stock value after calibration: sub: yes front: 120hz center: 150hz surround: 150hz surround back: 150hz surround back channel: 2ch lpf or lfe: 80hz I used to have intellivolume to +12db, but once I read about it on how it was working, I understood why the sound was bad and turned it back to 0, which make the sound crisper but a bit less high (not that much). Now, I also have the volume setup properly for each channel, except the center that I gave higher sound volume (about 2-3 more) because I always have problem hearing/understanding what people are saying. While this happen, it is the main reason why the sound is so high when I listen, the voice coming from the center volume is low. I have my EQ off and all optimizer/filter off. I'm on manual EQ, where I can set each channel sound, but there all are at 0 because I'm unsure what value to change: Subwoofer 25hz 40hz 63hz 100hz 160hz Front 63hz 250hz 1000hz 4000hz 16000hz Now, this is something I'm unsure. The calibration value entered aboce (not the eq), what does it mean? As for what I understand, it would be the crossover. Meaning that anything from 0-80 is sent to sub. Then anything from 0-120 is sent to front, and 0-150 sent to center and surrounds + surrounds back. But then, why can I crank on the eq HZ that are higher the 120? Like you can see, I'm all lost with all these settings and reading on the subject since to simply lost me even more. I won't ask for what the value should be since it's all down to personnal preference, but I'd like to understand all these settings, how they work and how to "play" with them to change the sound experience properly. I know THX have a 80hz reference for the subs, but that's about it. Thanks!
