I am on a trip and the only measurement I have is a photo of the latest version of Dirac Live measurements screen. Sorry for the low quality.
(Based on 17 point measurements done by MiniDSP SHD using a calibrated UMIK-1 with its own calibration profile installed. Measurements were repeated multiple times using between 9 and 17 varying points all as per instructions all looked almost identical.)
In gray is the response corrected to my preference curve, the dotted yellow is my personal preference curve. The important is in pink: the uncorrected response in a real world room. Let's zoom in to some details, going left to right:
The overall measurement window matching the Dirac requirements in my case is 21hz - 21khz (bound by the vertical yellow curtains), with the sub crossed at 80hz. There is a SVS sub resulting in the bass bump below 80hz - I like my bass slamming as you can see by my preference curve's bass shelf.
- The 40-110hz hump is due to the placement of the speakers and the sub 15 cm against a wall, as seen above on my photo of the speaker. I didn't use the A306 built-in preset to correct for placing close to the wall because Erin advised me to leave it this way and better let Dirac take care of that.
- Around 3 db deviation at 200-300 hz, again due to the room, really low, gradual and wide enough not to be audible even uncorrected.
- Very linear mids, subjectively they are very coherent with truly impressive tembre nuances. And they feel fast and revealing but without any edginess.
- The highs are very extended and very linear, all the way.
Short version: Overall crazy flat and linear for real world, at any price range.
My personal take is that this is an amazing uncorrected room response and can easily be used without room calibration in my case. Listening confirms that.
And subjectively they sound wide, very fast, precise and detailed. Most importantly with an "authority" that is absolutely unexpected given their medium size. I don't hear any uneven parts of the FR and the "placement/separation" and "large stage" are top notch.
