Hello. Here's the thing: One of the less pleasant quirks of the axe FX and it's modelling accuracy is that you have to set the speaker resonant frequencies manually. The speaker settings are very important in order to get the "Real" sound and most users miss that. In most cases, the result is not authentic/physically accurate as users usually end up using the default settings, or in rare cases, more experienced users set these by ear. Most of us don't own the cabs in the IR list, nor do we have the means to measure the real cabs we have, so we see these "It's not like the real thing" comments. My idea is that IR's files could also contain resonant frequency settings, so when you load them in, the speaker page also updates to the right settings. This could be optional, of course. When switching Amp models, the speaker page settings could stay authentic to the cab, and we wouldn't have to set these manually every time. When releasing new cab packs, the developer should also measure the cab resonant frequencies and embed them to the IR files.
