My listening position is 12' from the mains and the mains are 12' apart. The Left main is 13" from the wall in a corner and the right main is 12" from the back wall, five inches from the right main is an opening to the hall/living area. I have poured over the Audyssey faqs. and they say you can raise the crossovers but not to lower. The 8801 is awesome I hear detail I have not heard before and my surrounds have come alive!

Any help is appreciated, pleeease!

I am not the biggest Audyssey fan so I will let others respond. It could be a bad mic.

Thanks for finding his post Jim.

I'm no Audyssey wizard but I don't see a problem with the way it set the XO's. I would toe them back out a little more to get as close as possible to the 80 XO number and call it a day. Remember you can raise your XO points workout effecting the Audyssey filters but not lower them. On paper my Revels go down to 33Hz but my sub handles everything below 80Hz much better, as is the case with most of us IMO.
post #8704 of 11304
I'm pretty sure you can lower the xovers, it's just not recommended. I have some very large speakers in my system. Audyssey set my mains to "full" I raised them to 40hz. It set my side surrounds, which are quite large, to 60hz and I lowered them to 50. I left everything else alone.
post #8705 of 11304
Yes you can lower them, but if you do Audyssey is just not filtering below that point. Audyssey did almost the same thing as it did for you, set my mains to large and full range, which I promptly changed to small and 80 XO.

Anyone install a 7minute upgrade last weekend?
Did it do anything?

post #8709 of 11304
Did the upgrade last weekend, can't tell a difference. Glad it went well with no hiccups.
post #8710 of 11304
Be good to see description .
post #8711 of 11304
Is this a different 7 minute upgrade from the one awhile back?
post #8712 of 11304
Hi Waboman and Kal Yes it's the same Firmware released awhile back wink.gif

I don't remember anyone saying that they compared the 8801 to the ADA, I could be wrong though. But this looks like a no brainer to me. The ADA is coming up on being 4 years while the 8801 is less than a year old, it's only 7.1 versus 11.2 for the Marantz. That would be enough for me wink.gif

^^^

there would be those who disagree:

http://www.avsforum.com/t/1459947/best-surround-processor-currently-available

I suggested they add the 8801 to the poll but no one was interested in doing that: I think it does not cost enough to qualify smile.gif

Yep, I saw that awhile back and figured it was because of the price we were not "in the mix"
But it's one reason the 8801 was appealing to me.
post #8717 of 11304
The Dstat would be my choice if money was not a concern, although I've heard it's not so easy to set up. Realistically I bought the 8801, all new front speakers, a new sub and now a plasma panel for the price of the Dstat. I might even be able to include room treatments and still have money left for a nice dinner biggrin.gif

I have trouble setup my new 8801 in the Audyssey setting, I have the 8801 pair with the Sherbourn 7-350 and the paradigm CC690, when doing the setup, the center channel have a result of -12db, any chance I can reduce the output of the test tone, or lower the gain to make it less than -12?

I would try repositioning your center speaker if possible. If it's on a shelf and the speaker is set back some try bringing the front edge of the speaker an inch past the shelf. This will help reduce a possible reflection and it can't hurt to try. If that doesn't help post in the Audyssey thread they will help you smile.gif

Switch to RCA if you're using XLR' for the center channel, or adjust the gain on the amp if it can be adjusted.

You may want to consider adding a 12db attenuator to the line out.

I used this attenuators for my 3 subs biggrin.gifbiggrin.gif Before the attenuator I had issues with the sub level too high. These fixed my calibration issue.
post #8724 of 11304
I appreciate your response. It just seemed strange that the Onkyo PR-SC885 set the crossover at 80hz. I know it is not the same version of Audyssey just thought that it would set the c/o a little closer to the 80hz point. The strange thing is that the center has the same speakers as the fronts and is set the same distance from the wall and it was set at 40hz. Thanks once again for your help!

Yup. Although more frequently used with very efficient subs, they work well with very efficient speakers too. smile.gif

I would contact your dealer. Don 't assume Audyssey is infallible. That does not make sense.
post #8728 of 11304
The crossover frequency is determined by the receiver manufacturer's software, not Audyssey. Audyssey measures the speaker's "f3" frequency (the point at which its sound level has fallen off by 3dB) as measured in your room .Then the receiver's software picks the next higher available crossover frequency.

Room reflections (and attenuations) will determine the total amount of energy arriving at the microphone at a particular frequency. They'll differ depending on the path that the sound takes. In other words, there's no reason to expect a priori that the crossover frequency needed in your listening environment will be consistent from one identical speaker to another if they aren't placed at exactly the same location in your room. There's also no reason to expect that they'll be what the manufacturer measured in an anechoic chamber.

This Audyssey FAQ answer may help:

 

c)1.   Why are my Crossovers set differently to my speaker manufacturer's specification?
 

As may this one:

 

c)6.   Why is Audyssey setting different crossovers for my identical speakers?

Have a look at the AV-Forums 8801 thread - Adam used to own an ADA and has now switched to the 8801 - He compares the two in a couple of posts IIRC
