Hey all

With the latest Audyssey versions in AVR's, like Marantz AV8805, is it possible to limit Audssey's digital room EQ to 300 Hz (or whatever one wants) for example? And keep frequencies over 300 Hz (or whatever one wants) un-touched by Audssey?

Thanks in advance

Definitely. The app makes it easy to create multiple EQ profiles from a single successful calibration. In my case, I adjusted the EQ cut-off frequency for each "pair" of speakers, front L/C/R, surround L/R, front height L/R and rear height L/R to find an optimum solution.

While you are at it, change the poor default curve. It should not be flat, it should look somewhat like this:



Of course if your bass goes deeper, no reason to limit it.

Also, try not restricting the EQ, but turn off Midrange Compensation (MRC) =, which is the 3dB dip at 2kHZ, and try adjust the target in the image above, then toggle Audyssey on/off and see which you prefer. Adjust the bass and treble to taste of course, but it likely isn't too different.

A good house curve but a bit exaggerated IMHO. I'd limit the roll-off to about 5-6 db.
YMMV

In the treble? If so, you are looking at the measurement graph for the speaker, the light purple line (labeled "LCR + Sub Target" in the legend) is what I am referring to, which shows 20kHz as around -3dB from 1000Hz.

Now, that is an old Harman target (below in black), as far as I know, this is their current target (below in blue):

It's for over-ear headphones (using their specific head, so can’t translate to say InnerFidelity's measurements), but it should be a 1:1 translation to decibel level differences between the speaker target linked earlier, so a bit more bass and a bit less treble, which seeing as how 20kHz being -5dB below 1000Hz is a common starting point, makes sense.

Again, its a curve that's supposed to be good for the masses. Individual target curves are gonna differ slightly, but this should be a good starting point.

Thanks for all the info. Do Harman also say this should be a direct translation to speakers? @Floyd Toole
