I just had a question regarding Audyssey XT32 . Just looked at the AUDYSSEY WEB SITE . ...Does'nt Audyssey potentially put Dozens , if not hundreds of filters on the Peaks and Nulls (which i thought was a no-no) on the FR to correct it .?? Is'nt this the complete opposite of MIN EQ ??

Sweeeeet set-up and such a nice space. Appeals to the industrial designer in me.

A smoothly rising or falling response can also be drawn with a flat line.

Forgive me, I've not been getting out much lately...

Don't we use the word "flat" in a much broader context? Aren't our LCD monitors setup vertically on our desks that have a flat panel display? Isn't the business use of a "flat rate" an everyday example having no orientation properties out in the 3D world? Finally, how would you refer to this if not called flat, regardless of orientation!!!! Just wanted to write something!

Thanks for your comments Rene. What I was having in mind was that Audyssey during the first measurement (at the MLP) takes care (among others) of time alignment of all speakers in the system ("time" is better word here than "phase"). But if there are fronts like the Jamo S606 that have drivers at different physical distances to the MLP I'm not sure the test will not be thrown off. S606 has the tweeter and mids up front while the woofer is side-mounted.

Rene, anyone?

That's probably a contributing reason for why everybody (serious?) stick with calling it 'distance'.

While we are at this subject, what's your (or others reading in) opinion 'bout speakers like the Jamo S606 with drivers "all over the place"? I looked into the spec sheet of this particular speaker and found that the internal cross-over of this box is rated at 150 Hz. This suggests to me that even with a cross-over set in the avr to 80 Hz there will be a range between 80 Hz and 150 Hz where this side-mounted woofer may cause unknown/unwanted phenomena for Audyssey of which acoustic results are hard to discribe/predict without hearing it, yet remains just a theoretical approach on my side neede to be further investigated.

But I'll point out that flat panel displays are flat whether they're level or not, as are all other flat surfaces.

Hi All,

Looking at newer recievers by Denon (4311ci) and Onkyo (3008). Both have XT32 in them. The Denon being the one with installer ready turned on and Onkyo not turned on. I called Audyssey to ask if maybe it was a typo and they said no it's inside the Onkyo but the company chose not to turn it on. I asked the question of. If Onkyo wanted to turn it on in an update could they? Audessey said yes they sure could. Well I'm not very hopefull on Onkyo doing that but the real question is should I go Audyssey Pro kit capable reciever (Denon) or do I really get enough resolution filter adjustments with either reciever with XT32 and AS-EQ1? I do want it to sound as true to the mixing stage as it can be, no more, no less. I'm old school and have done the fun of tweeking the Berrenger PEQ days with a mic and laptop software measuing tape in hand. I've setup the Outlaw audio crossover that I felt the home theater world needed years before in it as I used in the profession audio and car audio world. For me now I want to do more watching and enjoying movies/TV shows and set it and enjoy it. Thats why I bought the AS-EQ1 to begin with. To balance out the bass problems in a room with using 1 or multiple sub's. If I move things around in the room then sure run the setup again even if you recommend the Pro direction. I'm currently using a year 2004 Yamaha reciever that EQ's single location mic's the sweet spot that doesn't work so well with AS-EQ1 or the fact that I want each seat to hear as close to what another setting location hears true to the sound mixing stage, which has brought me to buying said reciever with Audyssey in it.

Thank you for your time...

After the EQ process is complete and you set all speakers to small, is the "Audyssey" light still illuminated on the front panel?

I will reset the AVP tonight, see if there are any upgrades and re-run the whole process again following the Setup Guide.

What I do not understand now is why just the center Genelec 1038 shows a crossover frequency of 120Hz and I get nothing for any of the other 1038's or the Genelec 8040's.

Also I am still trying to determine if I should be seeing EQ curves for the subs as there are none, but I see them for all the other speakers.(Denon was not much use here). Are these curves representing the applied Audyssey EQ or the frequency response of the speaker?

So far I am not very impressed by this EQ process, but its probably operator error!

If you are getting calibration chirps from the subs, then Audyssey knows they exist. Changing satellite speakers from large to small should not turn off the Audyssey box. I don't think we have determined the root cause of your issue yet.
