After reading your description, I recalled that Sterophile had reviewed and measured your speakers a bit back and decided to look through its numbers. A couple of the measurements do seem to substantiate your impression. From about 3.5Khz-12Khz, the tweeter response is elevated by about 5db. Now this could often be used to balance a design that has wide dispersion differences between drivers, but the following dispersion graphs show a wide and well balanced dispersion. The other figure that is of note is a resonance in the tweeter at 20Khz, which will be audible to mostly younger ears.
That being said, no cable will be able to tame this treble response to your satisfaction. If the speaker has that first row presentation, the extra treble energy would be even more apparent. With that information, you might be able to use an EQ to balance out the treble, but the results may still be not to your liking. Some designers do add a little rise in the upper end of the treble to add a bit of air, but this design has its rise through most of the usable treble range. Good luck with it all, but I feel you don't have an ideal match for yourself.
