I'm not planning on doing anything about it. I spent 25 years in a manufacturing environment running CNC equipment and I've been an avid shooter all my life...I can't hear jack above 10khz anymore anyway. It's probably why I'm so fond of single driver speakers too. (grin)

There's definitely adequate treble and pretty remarkable detail - I'm not missing any cynmbals. I just wanted to let you know you were spot on about the planars.
