Just a quick comment. This driver has a frequency response off-axis which is about the mirror of the on-axis frequency response. Together, they balance out the amount of treble radiated into the room. And you can tune the amount of treble by listening more or less on axis.
It is a very classic fullrange driver in that respect, this is one approach that has been known for ages, but works best with drivers with the right balance between on- and off-axis response.
There may be a part of the midrange where the off-axis response is too similar to the on-axis response. That can be balanced out by pulling that down a bit.
There are graphs for all these scenarios with this driver, but I am on the road and don't have time to find them.
