Comparing the top pair of curves to the bottom pair of curves, I don't see much difference between 2kHz-7kHz. Perhaps you're confusing the left and right channels of each measurement?
For clarity, the top two traces show the right hand LS6 and LS5/9. The bottom two traces show the left hand LS6 and LS5/9.
