One simple setting made a world of difference.

This is not precisely correct. While Dynamic EQ is off at 0 dB it is effective when the master volume is both below and above reference level.

Of course not too many folks listen at above reference, so Dynamic EQ doesn't often get a chance to cut levels.

Reference is VERY loud, and most music is mixed at a lower volume, and thus require less correction even if you are playing below reference.

It's basically telling Audyssey DynEQ that is should set the 'no-correction' level to -5, -10 or -15dB on the dial, not 0dB as for movies.

1)
Do i have to make a Audyssey run with the sub and just turn the sub on when i watch a movie ?

2)
Or do i make a Audyssey run without the sub and turn it on when i watch a movie ?

I guess that Audyssey will use other xovers when you run it with or without a sub (?).

So please advice what i must do, option 1 or 2 ?

Thanks........

just another question i have an onkyo sr-tx507. After the calibration is done my surround are setted to -10 but are loud too and so some sounds are disproportionate and overly strong compared to the frontal spkrs.

You must to know my surround are bose interaudio XL3000 60W power output

- setted to small
- distance 1.5 and 1.8 mt (is that ok but for me is better setting to 4.2 mt )
- they are orientated to the centre of the room. Is that ok or must be parallel to the wall? considerate that couch's extremes are a bit 'stretched forward and spkrs woofer is a bit hidden. (see the pics)

i don't understand because with dyn eq engaged the surround level is getting lowder and the sound has a overall loudness effect (bass and treble overlying midrange)

thanks ain advice

But the question is why no sub for music, or do your mains really go down low enough, with enough efficiency, that you don't need a sub for stereo listening? If you feel you need it for movies (to handle the low end content in the main channels and not the LFE) I would think music would sound rather anemic on your system.

Looking at your photos, you should really mount your surround speakers a couple of feet above the listener's ears. From the photos, it appears that anyone sitting at that end of the couch will get blasted.

That's what Dynamic EQ does: at lower listening levels it boosts the bass and surround levels to compensate for your hearing at lower levels.

I hate to say this, but if your other speakers are as poorly situated as your surrounds appear to be, it is no wonder you are having difficulty getting acceptable results when running Audyssey.

Yes, that's right. The purpose of Dynamic EQ is to preserve the octave-to-octave balance found at reference level. So, if you go above reference then you have more bass than reference (for example) and Dynamic EQ will apply a cut to bring it back to reference.



This condition should put you at 2 dB above reference SPL and so Dynamic EQ will be applying some correction, but it will be very small since you are within 2 dB of reference.

Justin from Australia here. I have just spent the last few hours reading heaps of pages I have missed my dog has been sick and I am behind on this thread My most fsvorite thread of any forum. I am not happy I am getting the best from my expensive system and after reading back all the pages It has re ignited a few questions for me that arent answered in the setup guide for Audessey.
Ok I have a really expensive Sunfire Sub a signature True EQ 12 16hz-100hz. It has manually or auto EQ with its own very good quality setup mic for auto EQ.
I keep hitting a wall here should I run the auto room EQ for the sunfire before I run Audessy? Or should I do it after? Not to answer my own question here but I would be messing with Multi EQ XT if I did that yeah?
After reading all the pages I have a pretty good "heads up" on my sub settings prior to running Audessy, I think I will need volume at 11 oclock maybe a bit lower. With gain? It is a measurement on how it integrates with your speakers so what is the best refrence setting for gain prior to running Audessy am asking this cause few of you have different ideas and am confused.
Some of you might be thinking What? His Sunfire only goes to 100hz I think this is a very conservative measurement that may not include LFE channel as I have listened to the more famous audio quality action movies with only the sub on and feel I am not missing anything there. Ok yes its a big call saying I have sound meters in my ears but I think it covers it. But I cant hear truly if I have a 100-120hz LFE gap.
My speakers are fairly timbre matched as in my fronts are the Paradigm Studio reference 100s and 690 centre my sides and rear surrounds are Dalis.
Even though my Sub cost 5k I would still like my Paradigms to do some work in the low range and Audessy allways sets all my speakers to large or full range so I am experimenting fronts and centre 60-80hz x over and surrounds 80-100hz in the thinking of 80hz being omni directional and anything under 80hz would maybe like my surrounds to have a supply of rear low range so theres my thinking of an 80hz x over for surround rears and backs.
If for some reason I am missing 20hz in the 100-120hz LFE range would this be picked up and reproduced by the other speakers?
Am trying to get an answer from manufacturer but the guy I need is on Christmas break.
I am asking these questions in anticipation of running Audessy again and getting it right without the sub or the onkyo cancelling each other out with sub EQ and XT EQ room correction.
I shall leave it there for now I have a few more questions but have asked a lot of you allready so I thank you in advance and look forward to you advice.
Kindest Regards
Justin

To be honest, shorter sentences, and a little punctuation will help in understanding your questions. I quit reading after the third sentence.

Originally Posted by bluesky636

Although I understand and fully embrace using Dynamic EQ at levels less than reference, I don't understand why I would want bass to be reduced at above reference levels.

I think this is your key question, to which the Guide says:

"F. If the sub has an EQ system, you can use it to tame large peaks (see item 1 below) before calibrating with Audyssey, but this is generally not recommended. Most of these EQ systems only allow one measurement position, and therefore only correct the amplitude (volume) for one seating position. Audyssey adds the benefit of measuring in the time domain for multiple seating positions to create an acoustic bubble.

1. Narrow peaks or dips in the response below 100 Hz that are 1/3 or 1/6 of an octave wide can be improvedbut not eliminatedby Audyssey Mult EQ XT.
a. In these situations, the built-in subwoofer EQ systems might be useful."

So, if this is your situation, run the Sunfire eq before running Audyssey.

I dont have meters and such so cannot tell if the EQ on the Sub is warranted or I should just leave it at out of the box settings.

At least know I kinow if I do do it it is to be done prior to Audessy (Iam not spelling that right am I LOL) Must list that in my firefox spell checker. So will re run today maybe twice over next few weeks and see what the effects of EQ prior and non EQ prior are.

Thanks again

Exactly how much would of course be determined by the results of the much-more-recent Audyssey/USC research.
