You really aren't getting it are you? When you use room correction, you are designing target curves yourself
, as you will be the ultimate judge of what you want in terms of sound. Personally, I think a perfectly flat line leads to sibilance because of the way most recordings are recorded. For a given position, if you let the mic take a reading using impulse repsonses (not a simple sweep tone) and give it a target curve, it will automatically calculate the time, level and frequency response adjustments that need to be made to give you your desired curve
at that position. Realize that drawing a curve is no different than sliding a scale, just far more efficient and accurate, with more factors being affected.
Again, as much as you think you know, it is obvious your experience is limited in this case and you really don't know much about what we are talking about here. Why embrace ignorance? Why not educate yourself or at least experience it before taking such a definitive stance? It's not like I am talking about power cords or cable lifters here. Reviewers for both the Absolute Sound and Stereophile went into their reviews of room correction with the same ill conceived notions as you. They both walked away stating that advanced room correction should be mandatory... and that, in the case of Stereophile, was in 2001. I am already using a significantly more advanced system than was available at that time. I guess you really won't understand it until you experience it.
I am only talking about this because I believe it overwhelmingly benefits the audio world. Even though I have all sorts of gear, I'm very clear about which of my gear is largely eye candy and which truly makes a difference. Other than speakers, the only piece of gear you will ever hear me talk about in terms of night and day differences is the TACT room correction. I'm also not some fanboy of TACT. I bought their gear because I simply could not ignore reality. I'm hoping that by raising awareness and creating more demand for such a crucial technology, whether it be from TACT or another company, it will make advanced room correction a common feature and more affordable for everyone. I considered funding one of the correction companies for that express purpose. For god sake's it even makes fletcher-munson based corrections for different volume levels! Everyone needs it and deserves it.

I don't need to hear every piece of equipment in the world to know whether a room correction device makes sense or not. I know enough about phase and timing to know that in an average living room with a two speaker setup, there is absolutely no need for timing correction. Put thirty or forty speakers in a concert hall, and you will. I also know enough about equalization to know that it can make a huge difference, but the only way to judge the degree of correction needed is to tune by ear using a tone sweep. I've tried many automatic eq devices, and the problem is that using a mike to adjust sound for human ears is like trying to read a book with someone else's eyeglass perscription. That's why they have EQ boards in recording studios, and that's why the recording engineer adjusts them, not a machine. It's no different in the home.
