Bear in mind that room equalization software really doesn't know what type of signal it's processing. It attempts to compensate for infelicities in both speakers and room acoustics.
Also, quality subwoofers can do a much better job of handling low fequencies below 120Hz than even the best floor standing speakers. Note that the specs for those speakers just say 40Hz-20KHz, not saying if the low frequency limit is for a 3dB decrease in signal, 6dB or even more. Most music doesn't go extremely low, but bass guitars and drums can benefit from good low frequency reproduction.
