Pretty simple answer, if you think about it. It would be impossible to place the microphone back in exactly the same spots that the measurements were taken. Since results can vary significantly, depending on where the mic is placed, they would not be valid.

"...the Level Calibration for your subwoofer will be within a range from about -3.0dB to +3.0dB..."
Should I aim for 0db? Is 0 db the perfect value?

Also, I havemy speakers very closeto the rerar wall and tv. Should I separate the speakes from the wall and tv at least 10 cm? Last time I ran audissey it seleced 40hz crossover, while my speakers are rated for 60hz - 80hz effective-.

That is a good point.

Please allow me to make the bolded part more clear. In a system without a subwoofer there is no way to set a crossover. There is nowhere to re-direct bass. All speakers will default to Large.

Hope this helps a bit.

No, my fronts are large, the center is small but can be set to large. Audyseey defaulted it to small 40hz. Im wondering if this is optimal. Ive toggled between 40-80 hz all night and cant notice any change for the life of me.

You are right, I just looked up your Marantz 7008 and the Manual says:

"For speakers set to “Small”, low frequency content below the crossover
frequency is attenuated to the speakers and the low bass content is then
re-delivered to the subwoofer, or the front (L/R) speakers if they have been
set to Large."

The reason you don't notice any change is that there is probably no real contents in the Center channel below the selected crossover point, even if it is set to 80 Hz.Second reason, with contents below 80 Hz our ears loose the ability of sound localization.

Any plan to get a sub?

Don't overthink it -- there is nothing magical about a 0 value vs. -2 or whatever.

If you run your system LOUD then you want to be careful about positive values as there is the potential for signal clipping, so most folks with serious setups shoot for a negative value, far enough negative to leave some room to boost and still say negative. For example, shoot for -8 to -10 range, so if you want to goose the subs 3-5dB you are still well negative.

But for most people who don't approach movie reference level volumes that's a non issue and you should just not spend any time worrying about it.

Since you have no sub, I presume if your menu offered "Sub YES or NO," you selected "NO," right? If you clicked on "NO," I don't see how Audyssey could have defaulted to "Small" -- where is the deepest bass in the center channel supposed to go? Out into the ether? EDIT: now that Feri has posted the excerpt from your manual, I guess the AVR redirects that bass to the front L & R, if they are set to "Large," and the center is set to "Small," and there is no sub. I assume that is bass management bass -- where does the LFE go with the configuration you have? It's amazing how much I don't know, even though I've been doing this for years!

Maybe you checked "YES" in order to trick the AVR into allowing you to use crossovers to keep low frequency sound out of your speakers (especially the center), because you don't think your speakers can take it? If Audyssey measured your center as having -3 dB at 40 Hz, that is pretty low for most centers, so congratulations on having a good center. But it might distort badly or be harmed if it gets high intensity signals at 15 or 20 Hz. I don't remember what kind of speakers you have.

With much source material, this might not be an issue. But if you play Pacific Rim, Star Trek Into Darkness, or The Grey, watch out! If you are going to play movies a lot (as opposed to CDs) you really should have a sub.

If you have no sub you can't set the FR/FL mains to "Small", but you CAN do so with any other speaker. Without a sub bass management is redirected to the FR/FL mains.

You can lie and say you have a sub, but I get what you mean.

That thought did occur to me, but I hadn't heard of it before so I didn't want to sound silly by suggesting it. That is a cool feature, and I'd probably leave it that way since your L/R are probably more positionable than the center with regard to distance from the walls. You have more flexibility.

Can your center really do 40Hz?

Could of sworn i picked no sub. I just followed the prompts. Picked skip for sub during set up and it detected no sub. I have klipsch RF82II and rc62II. . I dont want to mess up my speakers and i already had a sub, too uch for my area. So should i just keep the center small and bump from 40-80 or .. I'm raw when it comes to this

I'm not an audiophile I don't know if it can. Its the klipschRc62II. Right now fronts are large and its small 40hz. I want to minimize the potential chance for blowing out fronts. I dont turn up too loud and the bass from these is good. I utalize the bass reduction feature also. Still not sure to make the center large or leave small and leave it at 40. I dont need anymore bass. I want to minimize potential for overuse while maximizing sound. I switched the center too large and any setting I pick, from large center to small center 40 or 80 I dont notice any diff from it.
