I set a pair up for a friend and my impression was that they were a little brash - sounded like a low Q rise in the 4k region. I presumed that would settle down with break in; we'll see. These reports of very muffled highs makes me wonder if it's a QC problem, where capacitor suppliers are inconsistent, making some production runs of these speakers seriously out of spec. Then I remember that these have digital DSP to perform crossover and EQ functions–or is this not true? Anyone know for sure?
