post #6811 of 11283
So, now we are saying do Not change what the audyseey sets the crossovers to? because of no filtering of the speaker in the area that is not covered?

BUT... I should change that audyssey put all my speakers to LARGE, and change them to small??

and I should change when audyssey sets my speakers to full range to a crossover around 80?

on a side note...

what is the target settings that audyssey is trying for? if the speakers are good and the room is treated correctly? if (-12) is where audyssey gives up ... then are we trying to 0 it out with speaker and acoustic placement???

another way to ask is can one tell how well the placement of speakers and acoustics are in the room by the numbers audyssey applies after the calibration?

and if 0 is the desired setting can one just turn off audyssey and it would sound the same as with it on???

Thank you,
Bill

1.  No.  The rule is that one can (if one has a reason) raise the crossover point but one should not lower it.

2.  The target is for each speaker to have the same acoustic output.  If one is much less efficient (due to its design and/or placement), Audyssey tries to lower the other(s) in order to achieve that balance at reference levels.

3.  Not really.  Inherent speaker properties also factor in.

4.  Only for level.  However, turning off Audyssey also defeats any EQ.

not quite how it works and with him being only two "clicks" from zero'd out, I would say he needs to keep it right where he is. Audyssey will still measure -12's on the mains anyways...

which as AJ mentioned is a big no-no, however, what if your system needs no correction in the gap that you create by lowering the XO that much? Since you have the OM, it wouldn't hurt to at least try it out and see how it responds.

That is correct. Speaker as a whole. Having audyssey see the -3dB of the speaker too far up in the FR spectrum is the problem we are having, and it certainly is not the first time I've seen the issue either.

Swapped out the XLRs for the RCAs, moved seating foot closer and reran Audyssey. LCR are all now in the -8 to -9.5 range, subs(still on XLR) are -7.5, and the surrounds are now -2 to -4 range. Wish I could use the balanced cables but it's not gonna work without adding in-line attenuators, which are long and will cause me to have to pull my equipment out further rolleyes.gif so I guess RCAs it is for now. This time it selected 80Hz for the center and surrounds and 150Hz for the mains. I'll leave it there for now. And here is the latest Omnimic graph after that run.

24 hours after initial setup 1st impressions.

Yes Rennee Fleming does sound better than my 80.2 which is now in my living room with my 1981 B&W. 801s. XT 32 choose full for my Martin
Logan Montis versus 40 hz with the 80.2. I do not know how to change xovers without shutting off Audyssey

How do I do this? . I will do a pro calibration in a month or so after I learn ths pre/pro better which will let me choose xovers and eliminate mid bass correction.

Video seems fine and my AIX blue rays payed fine via HDMI . Like Audyssey on even though they are 96 kHz.

I miss being able to listen to radio and watch HDMI fios. If there is way to do this, please teach me.

I will try SACDs later along with some good jazz.


Over all nice unit and stereo is indeed an improvement.

As far as crossovers go settings>speakers>manual setup>crossovers.

At least your levels aren't bottomed out. 150Hz still seems high for the mains but your making progress.

After I do the manual setting ,the audio section tells me XT32 is off and I can not turn it on.

It seems his mains do 80hz - 26khz from what i see from the specs and are 100dB (horn). Seems a little high for speakers with 2 10" drivers but maybe that explains it. The subwoofer will i guess take most of the load up to 100hz.

Ok boss!

Strange I can go in change the XO's manually and XT32 is still engaged. What do have to do restore the Audyssey settings?

Very sad and he was a pioneer. I had a chance to hear the 901's well over 30 years ago. I wasn't impressed but I think it was their placement and the lack of knowledge from the owner on how they worked that made them sound lackluster to me.
post #6827 of 11283
I had the original 901's too and was similarly unimpressed

he sued Consumer Reports over their review... and won
post #6828 of 11283
After re running Audyssey using set up assistant, I could change the settings for my fronts to 40hz from whole with Audyssey retained in the audio menu .

I tried to save using the browser and it seemed to freeze . After saving for over an hour. I turned the AVR off and on and all was well. Not sure what went wrong.

post #6830 of 11283
I did not like the 901, imaging was somewhat what distorted for me. I chose the Dahlquist 10s then.

However his contributions to field were manifest. I think he enabled the serious listening of music for millions.

post #6831 of 11283
I am in the planning stages of putting together a vintage 2 channel setup. I briefly considered some of the older Bose, but I think they are too room dependent. I just want a simple 3 way speaker like a set of JBL's. I'm not familiar with Dahlquist 10's, but I googled them, they are an interesting design. How did you like them?
post #6832 of 11283
I appreciate the offer Jim, I'm just planning now. I want to get my HT setup finished first. But thanks smile.gif
post #6833 of 11283
The Dahlquist 10 were fantastic. A bit bass shy thus I used their sub as part of the system. Unfortunately they were too large for our living room after we moved. I then upgraded to the B&W 801s in 1980. We still use these fine speakers in our living room. After our daughter left for college we remodeled her bedroom for hometheater . That is where the Marantz is now working. I have Martin Logan in that room for fronts and Center ( Montis, Stage X, FX2).

Sound is very good . We listen every night 1-2 hours to stereo music via our DLNA server and Oppo except for an occasional tv program or movie.
post #6834 of 11283
Hi guys, didn't realise you shouldn't move the crossover down, is there a way to reset to the audyssey results without re-running?
post #6835 of 11283
Audyssey doesn't make the speaker crossover settings, rather the 8801 does that so you can return them to their original setting with no harm done to the Audyssey EQ. One way to return to the original settings is to use the RESTORE setting (p. 42 OM). smile.gif

post #6837 of 11283
So I just got the marantz on Wednesday and finally sat down and listened to some material last night.......all blu demo stuff. I've been messing around with running Audyssey which has been a little frustrating. After about 10 runs, it's always selecting a high XO for my mains(200Hz 7 of 10 times). Everything else is quite right. The very first time I ran Audyssey, it selected 120hz, but I can't remember the mic placement I used then. After reading some of the recommendations on mic placement in the guide at hometheatershach, I would say 6 of my 8 measurements have been within 3-4 inches of the mlp. The first run I think they were more spread out. I know Audyssey is measuring where your speakers are rolling off in your room so I'm confident it's accurate. You're not supposed to lower the XO Audyssey selects because there will be a gap with no correction applied, but if left at 200Hz I'm surely missing some material that my subs won't reproduce(my subs are +\- 1dB up to 110 Hz).....so not sure which is better. Maybe my mic placement doesn't need to be so tight and ill be able to get a lower XO for my mains......maybe 4 tight and 4 spread out.

I currently have left the mains at 200Hz and having said all of the above, I'm quite shocked!.................at how frickin good it sounds with Audyssey! Lol. I've always had very nice equipment, but have been using a very nice legacy pre/pro with an Oppo 105 doing all the decoding and passing through analog and just am surprised at just how much I was missing. Best way I can describe it is that there is just so much more detail in what you can hear.....in the entire freq band....even the detail in the bass region is amazing. Fleshes out the action on the screen so much better and therefore makes it more immersive. Call me sold on Audyssey, and I don't even have it dialed in the best I can. I usually adopt cool new tech early and am sorry I didn't here. My EAD pre/pro was so nice, but it was very expensive AND I spent more money having Noble Electronics do some nice mods too it......that's why I held on so long. Still an amazing piece, just doesn't fit anymore if you want an up to date home theater. More later.......

Jd, after I ran Audyssey my mains were at 250Hz and I changed them to 80Hz. Does this mean that everything between 80 and 250 is now not filtered by XT32?

Comfy, that is my understanding by a few who seem to know Audyssey really well, and that gels with answers I've read at the Audyssey blog by one of their techs. I see it as a problem either way.......if you lower it, you now have a gap with no correction. If you leave it, how many subs play material that high accurately?

Yes and it seems I'm not alone with the high XO settings. I'm hoping when I run XT32 again they end up being somewhere that I feel better about. If not I've read the pro version lets you make these settings? I'm asking here because I'm not familiar with the pro version at all. All this said my setup sounds better after I set the XO's to 80 rather than leave them at 250. Although I know this is just covering up a deeper problem.
