When I bought my Denon X4400 I expected the calibration would deliver a similar quality like Sonarworks Reference I am used to.
While the calibrated sound is an improvement - it was a bit disappointing to me that the sound quality is not as good.
So I gave MultEQ app a try and while the result was better - compared to the native result on the receiver - it still was not as spectrally balanced and neutral sounding as I am used to.
What is not working well in conjunction with the Audyssey mic?
For example using the FLAT setting (which should be the standard): WAY!!! to much highs.
Which I don't understand, because Audyssey claims the receivers contain calibration info about the mics. But the highs are so extreme, that this shows, that the mic is way too dull compared to the calibration data and therefore the treble become extremely boosted.
The flat setting is so extreme, that it can't even be explained by differences between mics.
So XT32 trebles are only bearable, if the "Reference" rolloff setting is used.
With that setting it's much better, but it shows underlying problems, which should be solved ASAP.
But Audyssey has not only treble problems. It severely reduces the subbass around 40 Hz and kills it below - on the same system and same speakers Sonarworks delivers wonderful subbass - even with its "neutral" setting and not one of the more aggressive settings that extend the low end.
Because of the unsatifying results I began to experiment with ratbuddyssey and MultEQ. I wondered if it was possible to copy and achieve the sound quality of the Sonarworks calibration.
And it worked! While the subbass problem still persits a bit, I was able to reduce the impact of the too high highpass filtering and get the treble under control - thanks to the ability of additional fine tuning in ratbuddyssey.
Between the bass and treble range XT32 does quite a good job on the mids. It was only necessary to adjust them to fit the spectral balance between bass and treble. After the adjustments it becomes hearable how good the room correction really works.
If you experiment yourself, be cautious: MultEQ seems to have some huge bugs - or maybe the conjunction with ratbuddyssey is the reason? I had noticed several times, that suddenly the MultEQ-adjusted bass response, although displayed in the MultEQ curve, was somehow lost after being transmitted to the receiver and the system sounded extremely different.
Therefore I strongly suggest, that you make copies in MultEQ and also always save the receiver settings on a USB-stick (make sure, the USB-stick does not contain a config.avr file! if the file is present, it can happen,t hat you see the message that the settings were saved successfully, but it's not...), if you have found a setting, that works and which you want to use as new base.
Less is more! What is also very strange, is the HUGE impact small EQ adjustments on the curve create. I am used to work with EQs daily and I know the impact [email protected]
usually has. Here a 0.5dB change can result in totally different sound - and strangely not only impacting the frequency range that was adjusted, but somehow it can affect the whole spectrum and levels.
Which makes it evenmore important, that you save good results.
I don't know if the settings from my curve translate well to every other system, because the mics are not individually calibrated.
I suggest to create the filters in MultEQ and not in ratbuddyssey. And also place them as close you can get to the target frequency and level (remember: 0.5 dB on this app, are NOT equal to 0.5dB in normal EQing - so be as precise as possible) to my numbers.
Dyn EQ OFF
Target curve "Reference" - MultEQ: Rolloff1 setting (choose BEFORE editing the target curve).
The additional filters for the target curve (according to ratbuddyssey):
f (Hz) dB
The boosts @20 Hz look awful, I know! But they are much less effective, because XT32 seems to add a highpass filter.
The additinal filters you see @120
/80Hz serve as anchor points: to reduce the impact from the lower filter on the higher bass frequencies.
MultEQ somehow acts strangely - but what counts is the resulting sound. And with these adjustments it is almost on Sonarworks Reference level.
Keep in mind, that the XT32 mics are not individually calibrated! I don't know how big the difference between the mics are, but if your mic is similar sounding to mine, the above settings should work well.
