I read "nearly" but didn't type it in, but those mountains above 10k are tall and ragged, far from "nearly flat", IMO, with all due respect!

No worries. Keep in mind the speakers sound excellent, despite the "mountains". More often than not, this is the case.

Unfortunately they do not publish off axis, which is where you typically listen to them.

Here is a diagram of a speaker that's half way between a full range and multi way; all drivers are the same woven glass fibre full range drivers and produce mid/bass, the middle one is full range with boosted treble. They sound like full rangers.

Wow...we have some kind of different hearing, or you had some defective Xs, or who knows, something seems plain wrong.......

Anyway, as I'm waiting for a Parts Express delivery today to work on a whacked out dodecahedron build, curiosity got the best of me with regards to the X's HF balance control.

Measurements are really easy for me to make ...

So ....here's two transfer functions just now made, at close range of one of the Acoustat X's i still have running in my bedroom.

Red is with HF Balance turned all the way up,
Green is HF turned all the way down.

Traces speak for themselves i think...

Who knows. We only ever had one pair and they had to essentially be given away. The 2s & 3s were better and quite a few of those went out the door..

Possibly a faulty pair then, who knows, condemn the model generally, why not, it's only an opinion.
