Someone toled me, maybe they just use a EQ-Curve to simulate them.
I've already tried some of the impulses in this forum and I'm totally amazed (especially the ones from brohymn and the sperimental pack blew me away

)
At the moment I'm still confused about that much variations of one impulse, but slowly I'm getting behind it

@EasySleazy
Already listened to your Clip and made my own experiences with my Line6 modelling.
You're right, you can sure hear a big difference, I was only wondering, why? ^^

My guess is this: The Cab simulation created by Line6, Native instruments and so on, can't be based on real cabinets. I think they ARE impulses, but not based on the real thing. It must be something like that thing that "someone" told you. EQ and some other tech stuff. It can't be based on the real cabinets because I don't think that, what is achieved by people that do this for fun, can be 5 million times better than the factory stuff. Imo, the mistake that companies do is that they sacrifice the realistic cab response/tone for the diversity of the tones (which is achieved by options like "Air", "mic distance" etc within the software...stuff that are destined mostly, if not only, for people that use amp simulations only for a 5 minute break from their work and don't take it seriously).
Speaking for myself, I would prefer just one or two cabs, with two or three mic placements for each one and only one mic, or perhaps two. The only difficulty that I think would emerge, should a company consider doing impulses, would be that if they wanted to be dead accurate with the impulse, they would have to do a lot of amp/cab combinations to achieve it (that's because the amp's power section plays it's part too).
In order to create an impulse, you need a mic, a real amp head and a real cab, a pc, and probably some other stuff too which I don't know (not necessarily expensive stuff). The only expensive thing is the real amp and the real cab.
About the thing you say "...about the variations of one impulse": There is a certain technique on how you'll capture the impulse. If we are talking about doing it with only one mic, then stuff like the distance of the mic from the cab, the settings of the power amp section make a difference I think. There is also some post processing in the computer I think. The room in which the cab is placed and the quality of the soundcard are important too of course). Check this stuff since I am not much of an expert in this. I just do clips hehe:
