The Super 7 and the older LS9 are top notch across the full musical frequency, although they achieve it differently. Both need to be placed carefully to get the most out of them. The servo bass of the 7 and the line array of the 9 have subtle differences in their lower octave, but both are stunningly real even at 25 hz. On both, the electrostatic drivers are superior in midrange and highs to the V series. The Super7 is absolutely as good as Tyson says for the full range. As for the LS9, I think they create a symphony hall more realistically, but probably give up a sparkle compared to the 7... up in the ultra highs I can't hear anymore.
