Sound meter + equalizer = problem solved?

Equalization changes the speakers input into the listening space; room treatments change the output of the room to the listeners ears. They are both useful but totally different tools. Every time you move a speaker, schangecthe toe-in, raise them up  or down, you are changing their input into the room. It is every bit as much equalization as turning a knob, with the added complexity of changing the speakers acoustical interaction interactions with the space. Equalization cannot fix a bad room, ever. That requires acoustical treatment. 

I have EQ for my system (a Schiit Loki is there but not hooked up unless something really needs it) and rarely use it as all I generally need to (rarely) do is adjust my subs...my large, untreated room sounds great as it has furniture lots of crap in it. I guess I know from decades of experience how to set things up to suit my tastes, so there's no problem to solve.

I would change 'Sound Meter' to 'Personal Preference'. It does not matter how it measures, it matters how it sounds. A flat frequency response not necessarily is the perfect response for everyone, or for every music genre.

Isn’t equalization only as good as the instrument used to measure its impact? Something to think about.

@falconquest thats true but I find all that is needed is for the meter to be close to accurate to make my ears happy.  Decibel app on my iPhone works fine.
