Ive only ever tried it without the centre and surrounds, and I guess its normal to expect the same not to be true for the fronts, but you never know, the system may just report them as not connected and carry on regardless. I need to order a new Audyssey mic as I lost mine somehow in a house move, so I cant easily try it myself now.

Try redoing the Audyssey set-up, but this time instead of pointing the tip of the microphone straight up, tilt it slightly away from the front speakers. This may help restore the perceived high frequency loss.
This may be a good suggestion. I will give it a try. Thanks.

Cant you just unplug the speakers so the system only detects the sub woofer, thereby fooling it into only eq'ing the sub. I dont have surrounds so I know there is no issue on that front, but I suppose how it reacts to no fronts will make the difference. It costs nothing to try though.
Yeah, this may fooling the onkyo 906. I remember during Audyssey autosetup, when it did not detect any speakers, it will bypass that channels and reported there was no speaker connected at that channel.
This may work. I will give it a try. Thanks Dan.

Anyone have any graphs of Audyssey MultEQ whom have upgraded to MultEQ-XT? I'm looking to upgrade my AVR/processor and I want audyssey. I get a severe allison effect -20db around 270hz and i have a huge +20db peak at 39hz. I can manually eq some of it with my current equipment but it is just not cutting it. I know that there shouldnt be much difference for the sub between the two eq's but im curious about the surrounds. has anyone noticed an improvement in the sattelite resolution on their graphs or sonically? I'm trying to justify getting a unit with multeq-xt.

MultEQ v MultEQ XT

Anyone have any graphs of Audyssey MultEQ whom have upgraded to MultEQ-XT? ...
I was reluctant to post these, as I took the measurements very early on, a year ago, when I was still learning how to get reasonably consistent measurements with REW, and before I bought a calibrated microphone.

091015.989vs790.jpg

In this graph, the light green line is from the Denon AVR-989, with MultEQ XT, and the blue line is from the Denon AVR-790, with MultEQ. It was taken at only one measurement point, of both front speakers so comb filtering effects may be present, with a Radio Shack meter so the accuracy at the high end and the bottom of the sub range are suspect. With all these caveats, the graph does support the idea that MultEQ XT does do a little better job of evening out the peaks and reducing the variation above the 80Hz crossover.

thanks, i'm very famliar with the specs, i've been following audyssey for years. I was looking for some real world info someone can give me some feedback on not marketing. Im looking for someone out there that has upgraded proccesors with the same speakers cause I'd like to see a full range graph comparing no eq with multeq to multeq-xt.

cool thanks bill. Its hard to say based on your results. I'd like to see some more. I've owned a pioneer with mccac and the radio shack meter. Back then I didnt' have a calibrated mic or rew then so no graphs. I now have the calibrated dayton mic with rew. They are a must have. I took some measurements and the cal mic and rew have allow me to do a better job manully equalizing my yamaha but I have some bad acoustics. I hope audyssey can fix me up. I know my system can sound better.

Here are my first full range graphs using Onkyo TX-NR3008 w/ Audyssey XT32, SVS SCS-01 mains, SBS-01 Surrounds, PB13-Ultra. Measured with cross specturm's calibrated EMM-6, 90 degree narrow band at the primary listening position.

Man....to my untrained eye that looks very impressive. What I found weird and have never noticed "at least not without going back and checking my own graphs" is how DynEQ effected the upper end of the spectrum. I knew it effected the lower end.

It is similar to what Dolby Volume does but the Dynamic EQ from Audyssey is not in the same league as what Dolby does, I heard the Auyssey version and was not too impressed, now the Dolby version impresses me every time I listen to it in there post processing, although I love what Audyssey does for EQ'ing of a subwoofer.

The output of the PB13 is impressive though and room gain at the lower end will nearly always come into play except in all but the largest of rooms.

Thanks for the XT32 graphs; the improvement in the 100Hz-300Hz range is really visible, which is what one would expect with the new filter resolution.

Would you, by chance, be upgrading from an earlier Audyssey receiver, and able to provide a comparison of XT32 with an earlier version, all other things being equal?

Thanks,
Bill

Unfortunately no, I was using a Yamaha HTR-6260, prior to this unit. I've only had the tools for rew for about a year. I have some graphs of some manually tuning I performed. Its amazing how audyssey can do in what took me literally hours of tweaking with the manual eq on the yamaha, a rane pe17 and rew, in only a few minutes and get the response just as flat. The dynamic eq gives it a house curve almost identicle to what my ears liked with the exeption of the boost on the high end. I like what the dynamic eq does with the sub but, I think the high end is too flat with it, I like the highs slightly rolled.

This was about as flat as I was ever able to get it manually with the Yamaha. Audyssey as you can see emasculates me and my toys. I actually feel kind of good about what I was able to accomplish.

I adjusted my sub gain according to the audyssey calibration which i didn't do before. I checked my mic positioning also. This is my final result with 3 positions. I wish it could get rid of the 250hz suck out but I think that is just the allison effect of having the bookshelfs on stands.

Ok, here we go. Denon AVR-4311ci. This is straight off the Audyssey auto config after it had me turn my right sub down to equalize it with the left. I identified that as the source of a big null between 40 and 50 hz.

The first graph is Audyssey off vs on. It's kind of strange that it reverses the peaks and valleys in the low end. It makes a huge gain under 30 hz!

Next is Audyssey vs Audyssey Flat. It does indeed flatten the graph out a bit. There's a +3 dB jump at 2k hz with Flat. Bass is unaffected.

Here's what Dynamic EQ does. At this volume level, it's mostly just boosting low frequencies. Since DynEQ is supposed to make the system sound better at low volume, it might be a more dramatic difference at a lower overall level.

dyneq_on_vs_off.png

Last night I improved my bass response by turning the gain knob back up on my right sub and raising them both to 0 dB in the receiver (Audyssey had them at -8). Tonight I turned the right sub back up to 0 dB and turned the gain knob up a bit as well while leaving the left sub at -8.

There, now that looks better. :D I'll have to do some listening to see if I prefer it this way or if I'll turn the left sub back up too.

Audussey XT32 / Denon AVR 4311ci / WinXP, Sound Blaster X-Fi

My first REW sweeps. I’m still learning about REW, Audussey and the 4311ci so I’ll apologize in advance if I have made any errors.
I’m using the RS 33-4050 as an SPL meter (for now)

I’m very happy with the sound even without Audussy, particulary the sound stage. Audussey definitely improves it.
I do have a couple of RealTrap tri-corners in place on the front wall and I’m just finishing off a couple of home built corner traps.
I’ll rerun Audussey and RAW after I get them in place.
I’m a bit concerned with the dip at 83.7 Hz , the peak centered around 6K and the rapid drop off above. The dip at 83.7 may be sub position related. I understand that the RS SPL isn’t very reliable above 3K.
I do have a couple of Bruel & Kjaer 4007 mic,s with factory calibration data, which I intend to try soon.

I am also started using REW recently.
To my untrained eyes the dip around 80Hz may be an indication of sub being out of phase. that is assuming it is the crossover point.

I have basic MultEQ vs XT32 if you are interested. only up to 400Hz though
