In ARC I was able to set the 'MAX EQ' to whatever freq I wanted. ARC's default setting was to 5K, and it would not apply any room correction above that freq (or whatever freq you changed it to up to 20K). Personally, I liked it not doing any correction above 5K. Is there any way to set Audyssey to not correct above a set freq, or does it always correct up to 20K ??
It appears on the Audyssey graphs that it is appying correction all the way up to 20K. I believe that was one reason it was sounding 'bright'. I was able to do an edit and bring it back down close to the un-corrected line on the graph, and it sounds very good, but if I was able to correct only up to 5-7K it would eliminate the need to edit the curves.
Second question -- is there any way to get a more accurate graph than the one that you can open on the Audyssey program. Not to complain, but its pretty cheap looking. You can't really see any of the numbers, or how many db you have corrected. Thats for the graph that you can open on the page where you upload the Audyssey to your pre/pro/receiver, not on the edit page.
Third-- Is there a way to change the subwoofer x-over ?? In my Integra menu after loading Audyssey, I can change the lfe x-over, but I don't want to do that.
Or does Audyssey automatically set the sub x-over to work with the x-overs chosen for your other speakers ??
Tom, DK if any of the usual suspects are here, but I'll take a stab at this:
a) AFAIK Audyssey corrects the entire range of frequencies with its filters. There's no way to specifically turn off a particular range of frequencies. There's speaker crossover points, where Audyssey doesn't correct below that point (e.g. 80 Hz, representing that speaker's -3db point), but you can't selectively turn off frequencies above the crossover. The Curve Editor is your best bet to tame or adjust (+/- 3 db range) your frequency response, as you'e done. I've done something similar with the Target Curve Editor on my Mythos ST fronts, actually boosting a little at about 8kHz to add some "air"
b) Not directly from Audyssey. You'll need external measurement capabilities to determine more accurate post-Audyssey curve results than the approximately 1/6th smoothing and graph resolution you get from Pro on its frequency response curves. OmniMic and REW are the most commonly software. However, you'll need a mic as well that's compatible with the specific software.
c) If you're using Pro, the best practice approach is to set the crossovers within Pro, so that the filters relating to EQing at the crossover point are optimized. Your best bet is to save your measurements, so that you can reload them in Pro if you want to make crossover changes to a specific calibration/configuration, and avoid the need for a fresh calibration when you want to try a crossover change. Note that this is different than with standard Audyssey. For more details, see AVS user kbarnes701's Audyssey Pro Installer Kit FAQ (link is in Post #1 of this thread on the first page).
Currently, there's an active thread of heavily Audyssey users exploring measurement issues and use of room treatments before using Audyssey or other EQ. Check out http://www.avsforum.com/t/1449924/simplified-rew-setup-and-use-usb-mic-hdmi-connection-including-measurement-techniques-and-how-to-interpret-graphs
. OmniMic is easier to use out of the box than REW if you want to measure FR quickly, but REW has recently become the most common standard among the HT enthusiasts that frequent this thread, and are delving deeper into more advanced measurements such as waterfalls, ETC plots, and the like. AVS user AustinJerry has put together a detailed guide (in progress) that would aid you in pursuing this direction; it's associated with his signature in his posts.
Hope that helps.Edited by sdrucker - 2/22/13 at 10:35am
