I just changed my seating from low back to seats with head rests. Im wondering if I should take my measurements with the head rests on (as it will be normally) or off.
My rear speakers are raised so the headrests don't directly block any of my speakers but Im sure reflections off the headrest will effect the sound to some degree.
Ive asked Anthem a similar question about ARC and they basically said have the room exactly as it will be normally, which would be with the headrests on.
What do you guys do?

Third option recommended from someone over at AVS: Head rests on but with a towel over the headrest of the seat thats being measured to reduce the reflection off the headrest. Seems like a decent compromise.

I agree with Anthem. A professional audio engineer > "Someone over at AVS"  |

That would need to be a really thick towel to actually do anything.
And I personally run my room correction the way anthem suggests as well. No point in making corrections to a room that’s different from the one you actually listen in.

OMG .............. you just have to rerun DIRAC ............... the difference will be huge ............... can't you already tell that everything sounds wrong   Then please tell us how much DIRAC changed the settings. I guessing SFA  Cheers Gary

I guessing SFA Cheers Gary Pre and post REW runs showed definite changes in my system IMHO EVERY time I redo DIRAC measurements I get very different post eq results confirmed wth REW. I can tell the new chairs really changed the sound of the room (also removed a coffee table) so I expect different pre eq results in this case as well. To be honest I don’t get the same level of consistency with DIRAC as with ARC or Audyssey but when it gets it right it gets it REALLY right. My speakers are dipoles which probably complicates things... |

No point in making corrections to a room that’s different from the one you actually listen in. Yeah it won’t do a whole lot in the mid low freq but I actually think it would at high frequencies. It doesn’t take much to atttunate high freq reflections. “Exactly as it will be” is a little difficult though, when I’m actually listening my head will be there blocking some of those reflections. Sounds like most of you are going the ARC route though. I sent an email to Dirac, I’ll let you know what they say when I hear back. Thanks! |

Most of the sound that will reflect off leather seat backs like this will be above that. Actually by default arc corrects up to 5khz and in one of the recent updates it WILL correct upto 20khz if you change the setting. And I’d still leave the headrests on. Try a few measurements with and without the towel, just a one position trial run. I’d be curious to see the results. |

Regardless, they say measurements above 5k will be unreliable so I think there measurement advice probably assumes <5khz. Good thought about testing with and w/o towel. I might try without headrests too just to see how that looks. I can actually hear the difference with the headrests off. I’ll post the measurements when I get them. It’s usually a looong process when I re run Dirac. I usually take a few different sets of measurements until I get one that both a) sounds good and b) measures well (particularly in the crossover to my subs, as Dirac seems to be a little hit or miss in this regard). Then I fine tune the target curve until I get the tonality Im looking for, this usually only takes a few tries now that I have a pretty good idea what sounds right. |

That’s why I suggest the single position, that way nothing changes but the towel or headrest removal. And it won’t take as long.

For sure, good idea. I just meant I probably won't get around to any of it until I have a nice chunk of time on my hands... Hopefully this weekend at some point.

Stick a popcorn maker in the sweet spot seat and then run Dirac. But you’re method is much more accurate I’m sure. 😂 |

Well, not the clean cut answer I was hoping for but Dirac supports response was to try it both ways (with and w/o headrests) and go by ear.
