+1. Me like documentation....I'm quite interested to know if the impedance model called Brit AX is the GB or V30 version? @FractalAudio

Why remove the choice to update?
I don‘t. Those who want to keep the existing impedance model can‘t they backup their presets before the update and restore afterwards?The more I think about this the more I think existing presets should get automatically updated to use an appropriate impedance model. Yes, existing presets will change but probably for the better.
Anyone disagree?
Resonance is the same for all signal levels. If you pluck a guitar string lightly, it rings out with the same resonance it has when you pick more strongly.
The data exists in each user preset to describe the impedance curve(s) in the amp block(s). It may contain carefully tweaked data or original factory settings. These presets may need to sound the same for the sake of a repeat gig or recording session.Firmware updates are changes. If you don’t want a change, then you have your best FW on the unit already.
I know pros still on like 5.x or whatever because it’s their current sound. Need a feature from later FW? Well gotta bite the bullet and adjust tones. It’s like buying a new different amp - gotta readjust.
There's the rub. 9 to 10 was a change that added an option (gain enhancer) without forcing you to use it.Should all presets created in firmware 9 sound identical when loading them in firmware 10?
Valhallir.at for example includes the speaker low resonance of their IR packs to the prescription on our website. So, if you want to use the exact resonance frequency (if you are using Valhallir.at cabs in the Axefx III stock cab section), you could take a look at our website.Does this mean the cabinet sonance should be known for every IR used and set accordingly in the Amp Block for best results? I don’t know the resonance of the cabs captured in almost all the IRs I use.
Rather than the default curve, the extra choice (NULL is worth keeping, IMHO, so your 'v10' extra choice is how it should be) should call up whatever is stored in the preset. Some folks might need continuity for the sake of a repeat gig or recording punch-ins later.i haven't read the whole thread, so i apologise if someone has mentioned this before, but i think there should be another menu option (or one that replaces "null") and that should be called "v10". this will being up the old default impedance curve. this will allow users to keep their old presets unchanged if they want and also allow them to have a look at what the old curve was and pick a new curve that's closest. like some of the old features we had access to previously with the II, this option could be removed in a later firmware if the consensus is that it could go.
i think the new firmware should choose a new default, as cliff suggested, but if you don't want to change, then you could simply to a batch update with fractool to set all the presets to "v10"

Yes. A bit of lube instead of "brace yerself, I'm goin' in dry!" Is that too much to ask? I'm not even saying I need a kiss first....That's all it takes, for a few months. Like you used to be able too scroll through FW levels in AFX2, until nobody uses it anymore and it quietly drifts off into legacy...
I think he already answered here:Will driving the speaker cabinet from the headphone output really work for this? We are trying to measure resonance in the cab, I would guess that the acoustic energy from the headphone out will be insufficient to excite any resonance? Are these resonances even linear in nature, or do they depend in loudness? @FractalAudio, any thoughts on that?
The impedance has a nonlinear component but it is very small relative to the linear component. IOW the amplitude of the wave is proportional to speaker displacement so the impedance curve is relatively constant vs. applied voltage. The nonlinear effects occur as the voice coil moves out of the magnetic gap and this is already modeled.
You missed: for a specific revision of firmware.
Presets are firmware version specific. They contain the value of the firmware they were last saved with in them as metadata.
There has never been a promise that presets will sound the same across anything but the exact same version of the firmware it was created. Ever in the history of Fractal.
You can always turn resonance down to taste from wherever it's at
This new impedance preset accessibility just enacts a long standing wish for test monkeys to be able to pull up existing real world speaker cabinet characteristics without having to enroll in school again...
