"Official" Audyssey thread (FAQ in post #1) - Page 112

I have enough mineral wool in my walls to insulate a small subdivision and enough mass loaded vinyl to sink a small boat, never mind the 6+ layers of material on both sides of the walls.

My issue will not be resolved by just adding a couple more corner bass traps.

So, spend thousands more to solve one remaining problem or put in a PEQ cut and bit of a LF rolloff with $500 of electronics? The answer is obvious to me.

My thinking is that it's the best way to do what I want because it shouldn't really impact the response at the crossover and hence audyssey can just do it's thing unhindered from there.

The short answer is 30 Hz at 1/4 wavelength is around 2.8m. I don't have that to spare for true LF isolation.

I have what I need from an audyssey perspective, thank you.

We could start a thread in room construction forum for further discussion...

My room has been treated with GIK panels (4" bass absorbtion in the 4 corners, 2" absortion on the front wall, 2" absorbtion on the first reflection points (sides and ceiling). The room is 15w x 26.7 deep, and is carpeted.

The speakers almost equidistant from the LP. Fronts are 8.1 feet away, Center is 8.4, Rears are 8.2 feet.

IMO, The Audyssey does a great job of EQing the frequencies. If your midrange, or highs are to harsh for example, Audyssey can usuall take care of that. I also found that the Audyssey did a good job with the bass. I use an SMS-1 to tame a 25-40hz room mode, and Audyssey didn't tone down the bass like some posters have mentioned.

I don't like what Audyssey is doing with the soundstage. While Audyssey does a great job of widening the soundstage, is seems to shrink the depth of the soundstage to about nothing. For example, if I listen to a piece of music in Direct mode, you may hear a singer up front, drums in the far rear, and maybe a guiter halfway back. If I listen to the same piece with Audyssey, I hear all three of those things on the same plane. Granted, the Audyssey is very enveloping (360 degree), but personally, I dislike having every instrument being the same distance from the listening postion.

It very frustrating for me, becuase I have run the Audyssey using a variety of measurement positions, and I like what Audyssey does from a frequency perspective, but I can't deal with the flat (albiet wide) soundstage.

Aside from re-running Audyssey yet again, using different measurement positions, does anyone have ideas for getting a deep soundstage?

Thanks,
Darrell

What went wrong? Did I have the master volume on the receiver too low when I ran Audyssey? Does that make a difference? It also put my center at 200hz and my fronts at 150hz. I was told to make my fronts 100-120hz. What should the center be at? I manually made my center and fronts both 120hz but I'm not sure what they should be at.

Any help would be greatly appreciated! It just seems my center isn't loud enough right now.

The master volume makes no difference during calibration. What were the reported trim values for each channel?

Keeping the same mic positions (using 3 listening positions, but doubling up with 6 measurements), I can process Audyssey a number of times and get wide variations (sub 2 = -8 vs + 8, center channel small vs large).

Anyone else notice this?

Well, I would not describe my Onkyo Pro 885 as being a soundstage depth Superstar to begin with, but you say that you get satisfactory results with the Denon in Direct mode. Assuming your are talking about 2 channel listening vs 5.1, I can offer two thoughts regarding why you may perceive that Audyssey has flattened your soundstage:

1) I notice that Audyssey shifts the entire soundtage forward, meaning the the performers are all more forward (but still relationally distinct) in the soundstage. It takes a while to get used to this, but I have and now I prefer it.

2) Audyssey processing includes a non-defeatable treble roll-off curve (I friend of mine has measured the frequency response of all of the Audyssey Pro curves with credible measurement tools and says that the roll-off is very severe in his system, even the "flat" curve). In my system, it is revealed as a lack of open-ness and air in vocals, strings, percussion, etc. It may be that this roll-off is eliminating the high-frequency spatial cues that help you locate performers in the soundstage (echo?) and this is affecting your perception of soundstage depth. Try this: Go into the Tone adjustment menu and temporarily adjust the treble setting up, say about 6 db. Does the soundstage depth improve? This might validate that the Audyssey treble roll-off is the source.

Also, you mention that you use the 3-middle, 3-forward, 2-back technique when you run Audyssey. I believe that this gives superior results for multiple listening positions, but might be sub-optimal if you listen mostly alone in a consistent seating position. Try running Audyssey while leaving the mic in the position that best represents your listening location and see if that helps.

Good luck.

Although these firmware changes have nothing to do with Audyssey, we received emails from people who lost their data because the update cleared the flash memory on the DSP. Please be aware that the only official (and supported) method for this and other updates is via the Integra dealer network.
