Hi Guys!
I actually measured Edifier's MR4 in its early days, too.
This is what I had measured before using Klippel's equipment and software, and the FR(on-axis) of the speaker tended to be similar to what @amirm had measured...
Can you please inspect my measurement?
It is an untreated 4000cubic ft office room . Edifier Mr4 + Temblor T8 sub
