I like that Dip, between 1 and 6 kHz.Nice mod but an 80dB scale makes everything seem a lot flatter than it is. 6dB difference from 2k to 10k doesn't seem that impressive, considering that with a higher resolution measurement rig like the Klippel high Q peaks/dips would show up more.
Here's No Audiophile measurements/review btw:

Doesn't seem to have such a pronounced crossover dip. He also did a tweeter mod including removing the grill and 'diffuser'. Ah someone just mentioned it as well.
That is not truly flat, but makes a LOT of music far more listenable.
