I've got an old ( 5yrs) pair of recently obtained ATC
SCM7 speakers. Something sounded wrong from the off, and I
think I've isolated it as a faulty tweeter. One is
distinctly louder than the other, and I can't reliably
differentiate the LF units, which seem much the same.

I've reached this conclusion by just connecting up the HF
or LF connectors on the speaker terminal panel. Swapped
across channels/sources/amps to rule out other issues.

Anyway, and assuming this test is reasonable, what might
the problem most likely be? Tweeter or crossover? And
sourcing ATC units? Anything like the Dynaudio closed shop
of recent experience? I will contact them at some point . .
.

All above is WELL outside my realm of expertise.

And another thing. I was doing some testing using a Windows
XP laptop as source - useful as I can use the software
balance control in the native sound mixer app. But how are
you supposed to centre it? Seems very easy to have it a
click or two off centre.

But THIS nightmare I am VERY familiar with. WHY no click-to-
center-default on the bal/hi/lo controls?

Stupid ****ing Microsoft!
