rerun audyssey with different sub??

felipe

Should I rerun audyssey in my HT setup since I replaced my sub?? Its in the exact location as the previous sub. I got the audyssey multieq version. Anyone knows how it measures/clibrates sub's?? Any thoughts??

P.S. I had a PSW110 sub that replaced my BIC f12 b/c of/the other half. Now I'm switching back to the f12 b/c the other half liked the sound of the BIC better...needless to say..I told her so lol.

Phasewolf

Yes you need to rerun it a if you have a new sub it will help a lot.

I reran audyssey..but I didn't like that it came up with different measurements for the other speakers even though I didn't change anything but the sub...so I didn't save the measurements..but I wrote down the sub measurements it made( distance and level ). I'm thinking to just manually change the current sub settings with the ones I wrote down..think that's a good idea??

Audyssey is not an exact science. I have had my issues with it and currently with my NAD gear. I'm no fan of this technology as I prefer to do my own calibrations.

With that being said, the placement of the Mic is critical . If you don't place the mic at ear height and in the exact location where you sit, you will get strange results.
Unless you know what you are doing , re run Audyssey and do 3 to 5 positions. Make sure there is absolutely no noise anywhere when you perform this. If anything gets picked up by the Mic, it will throw off your calibration.
As far as the new sub , con grads , getting new stuff is so fun. Depending on location , set the phase and level controls before running Audyssey. So here is some rules to follow.
Phase control - Front of the room set to 0 , sides of the room set to 90 , if you place it in the back of the room , run it 180.
Level control - play your main speakers in stereo 2 channel with sub and sit in the listening position. Either have a helper or do it yourself which sucks but whatever , turn the sub up till you can close your eyes and know exactly where it is. Then Turn it down slowly until you can't and think the bass is coming from the room or the front 2 speakers. Once you get it here , now you can run Audyssey.

Also back to the different results , this also could be due to your speakers are now fully broken in, maybe when you ran it the first time they where new. I usually go back to my jobs and recalibrate after a few months to dial in the system.

Yeah I've read that about Audyssey, it's never been that great. With that said however after research and whatnot, I didn't even plug the mic into my Onkyo, I set up the distances manually, levels manually, crossovers aren't activated mind you and I got good results, results I like. Then again, everyone's ears are different.

I'm a believer of calibrating to the Standard other then to personal taste. At least this way everything has a fair chance to sound it's best instead of somethings sounding great and others not so great. I don't use tone controls or EQ's without a Test Tone generator and a SPL meter. No way of knowing IF I'm even close to being correct or not.

Yeahhhh I kinda went for personal tastes, it's MY system and it's gonna sound MY way! You however do it for a living so you have to go with standards to get it to that stage of right.

Ive been doing it so long that way I don't even think setting it up to a personal taste ever crosses my mind anymore. Many years ago I use to do as you did, I'd juice the sub or the surrounds, maybe add some and take from there. When I go to a clients home who set up their own system , then called to have me come in to perfect it, I hear some of the personal tastes. I always leave with my client much more happy with their system after I calibrate it then what they pulled off. I do however get some who are so use to having the sub crack the walls they feel the bass is weak when I'm done. But then I get a phone call a few days later with them telling me their system never sounded that good. They can hear every detail etc etc etc.

When I run audyssey, I do all the 6 positions and my mic at ear level and I make sure the noise level is zero or near zero as possible. My sub I've had for some time and before the back n forth switch I left the level n phase controls on the sub untouched..in case I was allowed to use it again lol.

I was thinking the same bout the diff results from the other speakers...but I prefer the previous measurements so that's why I didn't store the last audyssey results. I read somewhere that for the sub, audyssey uses 8 times the "resolution filters" as compared to the rest of the speakers. What are "resolution filters?? Is that the same as an EQ? The only reason why I reran audyssey is b/c of the sub switch ( from a PSW110 to the BIC f12). Will I have to b/c of the resolution filters??

mantis

Yes resolution filters are basically Eq settings in a fancy package.
If your having issues with Audyssey I suggest resetting all settings and calibrate with a SPL meter. Measure out all speaker distances with a Tape measure and set up the sub as I laid out. Then Run Test tone and balance all speakers to 75db including the Sub.

Phasewolf

Let me ask this from the first mic location how far do you move the mic for thd next reading? Are you doing a tight mic pattern or one reading per seat?

From the first location I move the mic about 1meter (3ft) like I've always done it. I remembered earlier today why I might of got diff readings...I forgot to shut off my HVAC prior to running audyssey..oops. So, I redid audyssey with my HVAC off and I got the readings I originally had..even slightly better :-). What a difference an A/C can make. Back to/mic positioning, I follow the guidelines of about 3ft distance from each position.

OK I figured that is what they were. I found out today that it was my error and not an audyssey issue ( had the a/c on n running ). Thanks for the helpful tips tho..think I'll get myself an SPL meter just in case ;-). How much do those cost??

Phasewolf

When I run the setup I focus on one seat because that is where I am going to be sitting and it's what counts. Try reading this and see if it helps you out. http://www.hometheatershack.com/forums/audio-processing/68407-audyssey-multeq-faq-setup-guide.html

It really improved what I get from it by not moving the mic too far for each measurement. With moving 3 feel you will be trying to make it do too much when you really need to focus on one seat which when I did it made the other seats sound a lot better too sense your not over working the auto correct setup.

Good luck and please if you need help message me.

Phasewolf

A other way to look at it is this. If you take a data point and then a other one several feet away both locations are going to be most likely vastly different sound wise asking the auto correct to try to (fix) that large of a area is crazy and at best your going to compromise you main location.

But if you take several locations close to your first only move the mic 3 to 6 inches your building a sweet spot for yourself and sense your not asking it to correct 2 rolls back and 3 seats over it has less compromises it needs to make.

The worse you will be out is sometime and if it works trying it this way you will be very happy.

Basically you start at the master location that is the center of your head at ear height then 3" forward then move back to your first point but raise the mic up 3" then with the mic raised up forward 3" then lower the mic to ear height go back to the starting spot and move it 3" to the left then the final location go back to the start and 3" to the right.

It may sound like it will not do a lot but it will so just try it out and report back.

I have had Audyssey fail due to to close of positioning. Most corrections system need about 2 to 3 feet away from first measurement to work correctly. What is happening here is the correction system is taking measurements from the room in different seating positions so everyone can get an almost equal experience.

This is why I like MCACC from Pioneer way better. You only do one seating location , you can save up to 6 different positions. One sweet spot and everyone else gets what they get. King seat is the King seat.

SPL meters from Radio Shark are about $30 to $60 bucks. I have not purchased one in a long time so they might be slightly higher lower. Every single Home theater owner DIY person should own one.

LOL I told you No noise , it will throw off the calibration. Glad you figured it out.

Phasewolf

I have run it many times with how I wrote and have never had it fail it works very well. When I had a system that used MCACC I never got good sound no matter what I tried so I sold the unit and went with what I did.

I'm going to have to agree with mantis on this. Just tried the close positioning for audyssey, and it sounded good where I sit normally, but everywhere else I sit it didn't sound too good at all....so I reran audyssey the way I normally do..much better overall. Thank you for your input Phasewolf.

Phasewolf

It can take time to get right and it maybe a lot of how your setup is too. Every room is different and needs different things to make it sound it's best.

felipe

I agree. Every room is different. What may work for one may not work for another..its all relative. I know that when running audyssey there is one thing for sure to do...have NO noise ;-)

Phasewolf

Yea noise with any room correction system causes big issues.
