Most of you probably have way more knowledge about the technical aspects of this stuff but it still is baffling to me how many people claim and stand by the fact that it is impossible to get the correct sound in a room using an FR type speaker. I may not be a pro or have as discerning an ear as some, but I have been playing in front of a half stack for over 30 years. The first time I tried my ASM, I gave it a half hour, dialed through some random ir's, and thought there goes $900 down the drain. Didn't even touch it for months because it sounded like crap. Then I decided to give it another try, educated myself a bit, did some A/B ing with my real cab and finally got to where it sounded better not just to me but everyone in the band unanimously agreed it was better, at which point the other guitar player bought a fractal and asm as well.
My point is I think you can get there, but with the caveat that you have to pick the sweet spot as mentioned above and try for that sound. You have to work at dialing in the cab thump without muddling up your lows, etc. It could be that it's just the ASM that has me happy as others that have compared multiple solutions say that it sounds the most cab like. Now with both guitars running fr rigs, I can walk around the studio and it sounds remarkably uniform where before it was a shitstorm of noise. Anyway, rant over
