@tuga,
This was the response I got from the Autograph Mini at my listening seat in April 2020. The graph shows the left and right speakers individually. That was when the speakers were sitting on top of my Edinburgh cabinets, which put the Mini's 4-inch driver about 130cm above the floor, hence the lack of bass. (Anechoically the Minis are only supposed to be -6dB down at 68Hz). They were toed-in to cross in front of the listening seat, I estimate around 13-degrees off-axis but can't remember exactly.
This was the response after I applied EQ to soften the high frequencies. I also applied a small reduction around 500Hz to reduce a little bit of subjective midrange bloom. The graph shows the averaged response of the left and right speakers before and after EQ.
Now for the measurements you requested, hot off the press today! Nearfield from 1 metre, changing the horizontal toe-in by 5-degree increments:
Measurements with front grille off.
Measurements with front grille off LAYERED.
Measurements with front grille on.
Measurements with front grille on LAYERED.
As you can see, the mid frequencies remain exceptionally smooth when measured off-axis. The flattest HF response appears to be achieved with the grille on and an off-axis toe-in of 20-degrees.
Thanks!
I guess you can almost have them shooting staight (grilles off) if you don't have the possibility to EQ.
