Audyssey XT32 and those room response graphs

[v_squared123]

Alright so I ran audyssey with my 2.0 setup and expected to see more equalization options from the graphic equalizer. Unfortunately I found out that Audyssey only lets me adjust frequencies from 63 hz and up.

Problem is, I have a 2.0 setup with full range towers setup as large and wanted to adjust the low end frequencies myself. Now I dont even know if Audyssey equalized the low end frequencies either.

My question is now: How would I get access to the lower end frequencies from the graphic eq?

This got me really confused. I thought it would be similar to something like an SMS equalizer with on screen display and being able to adjust the peaks by bringing them down a notch. That's really why I wanted xt32....to see and adjust all the low mid and high frequencies.

So I want to know now how

1. How do I measure my in room frequency response and plot it on a spl vs freq graph

2. How can I use audyssey help me do that

3. And why does audyssey limit the equalization graph to 63hz? Why doesn't it go lower? I have my speakers set to full range...

Weird, I don't even get a graph at all when I run it. To make my measurements I use REW on a computer. Not sure about any of your other questions, and not sure what to tell you, but I know with my Yamaha w/ YPAO you can manually adjust the EQ graphs and on there it only goes down to about 60Hz, regardless of speaker settings. Also, not sure why you want to adjust what Audyssey sets anyways. After doing measurements in my room with REW (Audyssey on and off), I found Audyssey does a damn good job. Way better than anything I could ever accomplish with manual adjustments. The room treatments I added recently also made the biggest impact. Adjusting with EQ is only going to get you so far.

Sup Slick!

I guess I dont really want to adjust what audyssey does but I was suprised to not see the graphic eq not go below 63 hz...i assumed audyssey equalized from 20 hz and up....:S ?

And to get a response graph for my room I would have to measure it myself with a mic and computer software?

I'm pretty sure it does EQ down to 20Hz, I guess whatever manual graph you're looking at puts limits on it, you'd have to ask someone more knowledgeable about Audyssey on that one. But yes, for measurements it's easiest (for me anyways) to use computer + mic. I use REW (free and tons of guides on it around the interwebs) and for a mic I just use the Audyssey mic (found a study that claimed it was good enough to use without a calibration file, seems to do OK for me).

You use the audyssey mic for measuring your room response? Thats really cool! And if so, that would save me $50! Awesome

Yea. I'm sure people that are super serious about it would scoff at the idea, but the only reason I took measurements was to get a general idea of what my room treatments and Audyssey were doing for me, and it was good enough for that purpose. If you want as exact, detailed measurements as possible, you might want to invest in a USB mic or something and read up on some threads on how to properly use REW (most of those threads go way too in depth for me and I lose interest very quickly).
