Yes take a look at the product manual. The 0, +5, +10 and +15 settings you are finding are for Ext. In. It is useful when you are using multi-channel analog for SACD or Blu-ray. It is irrelevant to your situation so just ignore it.

If you have a CH SEL/Enter button on the remote press it and see if you can cycle through all the speaker channels including the sub. If you can, this is the setting you want to increase. It will read -12, increase it to +2.

The remote center button on the Denon is usually the quickest way to the speaker channel level settings.

Corner loading a sub will cause it to excite all the room modes (the frequencies where the sound pressure waves build up and overlap due to the major dimensions of the room: height, width, and depth). Normally this would cause very boomy sounding output, because those few frequencies are accented way above everything else. But with modern electronics, and things like Audyssey it actually makes sense to corner load a sub. It's much easier to attenuate (cut back) those three big peaks, than it is to fill in holes.

It still may not be ideal, but one sub in a room rarely is. But corner loading plus room correction can work pretty well.

Lots of activity, Ichigo. I'll comment on a few points. First, to clear up the terminology a bit, audio amplifiers and pre-amplifiers have fixed gain, and so they don't have "gain controls". The knob on the sub that makes things louder or softer is connected to a variable resistor which acts as a volume control by varying the amount of incoming voltage(from the receiver pre-out)which is let in to be amplified by the fixed amount of gain. You shouldn't have to set this above about half way, and the -12 adjustment that Audyssey made indicates that next time you run Audyssey you should set it a bit lower so that the end result is closer to 0 than -12.

The difference between the front left and right speakers is rather extreme, so check the right one carefully to see if possibly one of the drivers isn't working.

Generally, except in a square room(one poor devil here, who shall remain nameless, has one)the corner is the best place for the strongest and smoothest response from a single sub, so leave it there.

As for a suggestion of a CD to give your Axioms a good workout and being great listening too, consider this performance of Holst's The Planets, available at bargain prices.

They play a lot of electronic music genres but all their work has a nice drum beat that will give you a good mid-bass punch. The youtube video is a little week since when I play the an mp3 of this song in my car at moderate volume everything shakes.

I think Charles even likes them now.

Plus Exo-Chika is hot.

If you are really going to try to read the Denon manual this might help:

Yup, I do. Fun album.

Well in the morning after changing the sub to the corner I started to feel some bass. Should I turn the front or the back of the sub to the wall?? The Auralex Moped arrived today. I don't remember who gave me the suggestion of buying it. One thing I realized is that if I am sitting closer to the M22's I don't feel the bass and sounds like to volume of the sound is lower than if I sit on the back of the room, is that normal? Was it supposed to be like that? I don't know why but I haven't been very excited about Master and Commander, maybe because of some bad setting up I have done, but Silent Hill became a whole new movie with the Axioms. I am really thankful to all of you guys helping me out on setting up my system, guess that there is no other place like Axiom forum! Jurassic Park 3 is also nice, the Tyrannosaur foot steps sounds awesome. After wall mounting the Qs8's I rerun audissey and still gives me the sub -12.0. I am gonna try what John suggested and I will post it to you guys! What if I just use manual set up and set all for +12.0. I know this is not good, but what is wrong with that? Shouldn't a louder sound be better?

If we are trying electronic music I would consider the following:

DJ Babye Anne: I'm about to break

DJ Baby Anne: Bass Queen in The Mix

Bass Nectar: Cozza Frenzy

Turn off audyssey and try the manual setup settings I suggested. If you know where the sub control on the receiver is now this should take only but a few minutes to adjust it from -12 to +2 . This is a much easier troubleshooting method, takes less time and has less variables at play.

You have to figure out first if this is a settings issue or the sub. If we find out it is a settings issue then run audyssey after. All subwoofers are different and manufacturers are constantly changing the amp sections in them. Some might need a lot of voltage from the pre-out section, some might need very little and some are fine set at 0.
