The Onkyo is still somewhat new to me, as I came from a Pioneer Elite before it, so I'm still learning a bit with the Onkyo.
That's exactly what basshead was suggestion - changing the sub trim for music vs. movies. I don't like doing this either, although on my Denon I have a button that controls "Subwoofer Volume" and it's pretty easy to change on-the-fly...I still don't like doing it because i'm always I'm afraid I won't remember to change it back.
I have and it's even more lean on the bass in PLIIx. However, I do get pretty solid bass in *all channel sterero* but I pretty much despise this setting because I hate the stereo image running through my surrounds at the same time. Just HATE it! It appears I'm in the minority here, but I just want my two towers and sub playing music.
You are very much NOT in the minority...using "All Ch Stereo" for any sort of critical music listening or movie watching is ridiculous. The only thing it's good for is when you're having a party and you want music all around the room.
I'm surprised that PLII isn't giving you more bass though. Everyone I've read that has tried it has gotten more bass than with "Stereo".
To ask another question. As I was saying in my last post, I ended up setting the gain knob on the sub closer to 1 o'clock than 2 o'clock, as the 2 o'clock setting was hitting 90db, which I thought was a tad high, so I backed the gain knob back a bit, closer to 1o'clock. At this position, the sub was measuring at about 83-84db. I ran 8 position Audyssey and checked the AVR. Audyssey set the sub trim to -6.5db. I manually bumped it up to -3.5db and did some movie scene tests and things were better. My question is, does this sound about right to all of you? Or should I have left the gain dial set to 2o'clock on the sub no matter what? Though bass output for movies is much improved, I can't help but wonder, would it be even better if I had left the gain dial at 2, instead of back it off a bit? That said, audyssey setting the sub to -6.5db after calibration does seem to be in the ballpark of where I want audyssey to set things after calibration has run, at least from what I've read? Thoughts?
You are only running the sub 3db "hot" and saying that the bass still sounds "thin"...why don't you just keep bumping up the trim until it sounds good to you?? As long as you don't run out of headroom, you're fine.
Yes, you should try to set the sub gain to 2:00 and re-calibrate. As long as you're not "out of range" on the trim afterwards, you are golden. Ideally, you want the sub trim as low as you can get it after calibration so you have the maximum headroom to play with. Do you know the bottom limit for sub trim on your AVR? I think on the Onkyos it's -15, but I could be wrong.
