I even went to the sub setting in the reciever and selected +5dB istead of 0dB with a little bump in LFE. So far Audyssey has enhanced the sound of my system tremendously for both music and HT. Let me know what you guys think about the settings.


I believe what Dewd was referring to was that the first time, you said Audyssey set your sub at -12, which is sub-optimal. In your last post though, you said it set it at 0, which is more normal. From there you absolutely can adjust up or down as you prefer the sound. However, if you start at -12, you are limited by the fact that you can only turn the volume up, not down. For this reason, dewd was suggesting that you turn the gain on the sub down and rerun Audyssey (so that the natural setting from Audyssey would be something closer to zero - which it now appears to be).

On the contrary. With the exception of your own body and extra noise -- quiet is key -- when calibrating your theater you should have everything in there that will normally be in there.


To the contrary, throw pillows, blankets and bodies rarely reside in the same location time after time……… No different than moving furniture, which would require new calibration.

I’m tired and need a beer. Too many other posts to read right now.

After running the calibration, I thought I'd point out two things from the Tips & Tricks article that stood out to me.

From section VII B "After Calibration":
 Quote:
Raise the low-pass filter setting (usually incorrectly identified as a crossover) of the LFE subwoofer in the receiver / processor to 120Hz, if allowed

This seems like strange advice doesn't it?

And then, in the final note to the document, on the last page:

 Quote:
Before adjusting the trim settings, please understand that producing a calibrated setting other than 75 dB SPL results in reference level being achieved with the master volume set to something other than “0”.

This too just seems strange to me. I've asked the question about reference level volume in the past and the consensus was that there's no such thing because all movies/music/etc. are mixed differently, resulting in different sound levels at different volumes on your receiver. Not to mention different speaker efficiencies resulting in different volumes at the same gain level on the receiver.

Overall I thought the document was very helpful, but I don't think anyone should get to hung up on following the advice on either of these two points.

Jason

At the beginning of the thread the OP does say this

"Disclaimer: The following procedures may not work in all cases, as there are too many variables to account for in this document. If you feel further assistance is required, please visit the AVS Forum Official Audyssey thread, linked above."

So it is meant just as a guide and everyone should do as they see fit for their respective rooms and sonic tastes.

Don't get me wrong, on the balance, the document is really helpful. The reason I called the subwoofer point out is that I actually think it's wrong in more cases than it's right. Maybe with Bose-ish systems (small satellites with a decent sub) it would work, but it seems to run counter to most of what I've heard around here at the very least.

I have seen that 100-120hz subwoofer XO point before in other forums, some people feel it gives more clarity as you have eliminated the low end from your speakers and given it to the one piece of equipemnt that can really handle it well. I don't buy into it, I have tried 120hz all the way down to 40hz and I do not find it to be any clearer, as you said it could just be these are the ones with in efficient bookshelf systems.

Many subs will not be able to reproduce frequencies above 100 Hz. The EP500 for example is -30db at 120Hz.

This is the LFE channel, not a crossover. The .1 part of 5.1. This channel carries signals up to 120 hz. Some AVRs allow you to set this (for reasons unknown).

All films are mixed to 85db (peaks to 105, 115 for bass). That is an industry standard. Music on the other hand, varies all over the board.

If all films are mixed to 85db then why do I have to constantly adjust the level I wish to listen at depending on the DVD I am watching? I should be able to turn on the system, have it set up to -15, or where ever it needs to be for a standard 85db, and away I go, but it never works out that way.

I have found DVD's to be much closer to an actual reference point than any music cd's, but there is still room for error.
