Appreciate all the comments and suggestions. Will definitely put some thought into it and do a follow-up video. Thanks!
That’s pretty cool. I cant do that with Audyssey. At least I dont think I can, Audyssey sets the speaker level and delay(distance). My speakers also cause a weird phase detection issue. Audyssey thinks they are all out of phase, but I triple checked everything and its wired correctly. I contacted the speaker manufacturer and they know about this issue, its caused the the crossover order. Tweeter/Midrange Crossover: 3 kHz, 18 dB/oct, Midrange/Midbass Crossover: 300 Hz, 12 dB/oct, Midbass/Subwoofer Crossover: 100 Hz, 6 dB/oct. 18 dB/oct is not typical and has others with different slopes.
Thanks and yeah ARC can do some pretty cool stuff. Sorry to hear about the trouble that you are having but did the manufacturer offer any advice or does everything work as it should?
@@RandomDistractionsYT I was told to ignore phase warnings and it hasn’t been an issue.
When you adjust the levels in arc it is doing the same thing as EQ boost, EQ boost is not a bad thing as it's controlled well within the filter limits. The levels also only adjust the levels upto the max EQ level. So if the max EQ is set to 5k the speaker level is only operating upto the 5k point, effectively doing exactly the same thing as EQ. Auto phase only needs to be remeasured if you create new measurements.
Yes if you make changes you should always re do phase
@@Samzep There is no harm in measuring phase again but it's not required as the listening position has not changed.
@@corey8257 what you talking about if you make changes after phase example change crossover or add deep bass boost or low level extension in arc you must run phase again
@@Samzep The official answer from Anthem is you only need to rerun phase if new mic measurements are taken. When phase is measured all the parameters for potential crossovers points etc are stored in the unit and not in the arc file.
@@corey8257 wrong ! Any changes that I mentioned phase must be run again you seriously its phase the subs to mains so any changes that affect the sub or mains must run phase again your phase numbers will be different after making the changes
Hello
I have a AVR 1140. I added 2 front height speakers to my system but after doing the calibration the volume level is lower, compared to the prior calibration when watching a movie. Is there a set volume prior to calibrating that you have to sit on the AVR?
I think I read somewhere where you have to set it at zero, but is that 0 dB or percentage on the AVR?
Hi, and thanks for checking out the video. I noticed the same thing when I added my height speakers but I attributed it to my height speakers not being as loud as the rest of my system so it compensated for that by lowering the overall volume of the entire system. You can check out what it sets levels to see if it has to push the heights more than the rest of the speakers. As an option, you can turn it up louder than before to compensate for the lower volume to reach the level that is comfortable for you. Another option is you can adjust the system-wide target level after running ARC but you may want to double-check the levels of the heights to see if it is having to push them a lot to reach that level. There used to be a volume-level "hack" but with the updates that hasn't been necessary from what I have experienced.
9:40 that could be an irregularity with the mic - I doubt you would hear it, but every person is unique as is every room and every environment. To me, your measurements look ok (pre-adjustment) and I would be interested in how your speakers sound with less filters applied. Personally, I would like to see you utilize Quick Measure with your bed layer and see if you can adjust the tweeter aim to improve the roll off. You seem hyper-focused on correcting the very short "air" frequencies rather than long standing bass waves.
IIRC, your bed layer is roughly the same speaker, so they each should respond similarly. I think you can use that great waveguide to improve the responses of FR/FL/SR/SL, but C may prove difficult given the location/orientation. From the reviews and measurements I have seen for those speakers, I seriously doubt you need filters applied up to 20k. I am certain you can improve the response with positioning and eliminate the need for EQ filtering.
I feel as though I led you down the wrong path in my prior comment. My point was to use less EQ filters, not more. I am not a fan of the Guru's ARC method. I do not EQ above 500 Hz and found my room really opened up and is livelier without it. EQ was killing my speakers. The one caveat I would make is your heights. If those peaks are harsh to your ears, they need to be knocked down. Let your ears decide, not the green and black lines - they are guides.
Go watch Erin's Audio Corner video about Flat EQ is not Flat EQ as it is very enlightening with regard to frequencies and how they behave in rooms. There's a lot to learn in this hobby and you have a great attitude. Keep up the good work. If you think my opinions are not for you, that is fine. Let me know and I will move on.
That's a thought on the center issue (being the mic). I probably should have redone the measurement since it hadn't done that before and it was a strange peak.
Thanks for the compliment on the measurements, one of the reasons I picked the Arendals is that most reviewers really liked how well they measured so I can definitely try one with less filters.
In regards to the suggestion of using Quick Measure, if I understand correctly I would probably want to have the measurement increase since it seems to be falling a little short of the target line so would probably need to toe in to the MLP? Yeah, the center unfortunately is limited but one thing I thought of considering was adding a wedge to the bottom to help tilt it up a bit. It won't be much since the space is tight but maybe worth a try.
No worries, there seems to be a lot of different paths it seems like and I've found some things to work better for my listening preferences but definitely don't mind trying out different methods. I will try to do the 500 hz for the bed layers. I'll see how it goes for the heights but when they were at 5Khz they were definitely a little harsh and too noticeable so those may still get more EQ.
I'll check out Erin's video and definitely appreciate the opinions, like I said I may or may not use the final results but definitely willing to give them a try to see what it does. Will work on an update video trying some of these suggestions. Thanks!
If your graph doesn’t look good after 500 why would he want to set to 500 ?
@@Samzep you are jumping ahead. The goal is to use QM and see if the response can be improved with speaker position as the graph seems to show the tweeter is off axis. Maybe it is, maybe it is not. If not, then it is what it is. The point being, the more we can do with our mechanics, the less we have to do digitally.
Let’s see how our hero fairs in his quest. 500Hz is my number in my room with my electrostats. We do not yet know what his number will be. Shall we watch and see?
@@bigdogaxis best to leave at 5k many people cant move there speakers as i can not only speaker i can move is my centre i will put it higher so the 3 tweeters are level
@@Samzep every case is unique. If ARC’s initial result makes you happy, then be happy.
Hi there, which Arendal speakers do you have.
Hi and in regards to your question I have a 1723 S Center, 1961 towers for the front left and right, and 1961 monitors for the surround left and right. I also have a pair of 1961 bookshelf speakers that I'm hoping to use on my desk as computer speakers but still looking for the right integrated amplifier for that.
Oh also your mic position are good just too far apart i tried all i found tighter the better try same positions with mic but only 13 inches to 14 inch apart i think yours is further by looks in vid measure how far apart you did in the video and tell me please the distance from mic 1 pos to mic 2 pos ?
That is interesting about the mic position, most places including the official ARC Genesis website suggest at least 2 feet. Up to 3ft. Mine was probably around 32-33 inches. I thought that since I'm not the only one that sits on the couch and when we do we are usually off to the side of the MLP so trying to get better sound in those positions felt like would be good to measure out to those spots.
@@RandomDistractionsYT i have tried many best is 14 inch apart also i have tried the sub correction at 80hz waste of time just increase your subs at svs volume around 4 to 5 notches
first guy to show mic,,,, is that free,,, or extra,,, is it usb or mini usb
Thanks for checking out the video. The mic does come with the receiver and it's USB C at the microphone and USB A at the computer.
I would not touch the levels your just unbalancing your system that arc balance well i would not use more than 5k correction ? Also turn your subs on svs app to -22 lol on both and take a listen
Thanks for the suggestions and based on what Corey said in the other comment raising the levels is like doing an EQ boost so may not be worth it. I did receive another suggestion to try only adjusting to 500hz at least for the bed layers so will try that. I've tried something similar on the subs that I will touch on in another video.
