Thanks -- I have an e93, but did find the e92 settings an improvement (though probably not optimal, as I'm sure its not identical.
I have an audio spectrum analyzer and a pattern disc, maybe I'll hook it up and tweak it from there.
I had (incorrectly) assumed that frequency response balancing would have been at least reasonable from the factory....
Thanks again... If you do happen to spend time in an e93, I'd try the settings.
