Actually I am finding the extreme lows and infrasonics a bit hard to take. I've seen some descriptions of bass labelled "transparent" and that's a very fitting description for what I hear. BTW, it is not set hot nor cold but rather calibrated at the same level as all other speakers. There is simply no comparison to the 600v2.
