2048-point cabinet IRs

It's no use converting 1024-point IRs to 2048 points since they don't contain the necessary data. You need a WAV-file to convert to 2048 points. AlbertA's IR Converter can do this.
Parallel cabs are louder than a single one
Why do Cabinet blocks in parallel rows sound louder than a single Cabinet block?
Bakerman: "It depends on how you're panning. Assuming a mono signal sent to cabs: Stereo cab w/ Pan L and Pan R fully left & right will be the same output level as 2 mono cabs w/ balance L & R. If pans/balances are centered the 2 mono cabs will be 6 dB louder. Balance elsewhere would be between 0 and 6 dB louder, and balance doesn't correspond 1:1 to pan L/R for the same placement. Balances will need to be further toward -50 or 50." Source
Sound quality of a stereo cab
The Standard/Ultra used 512-point cabs in a stereo cab. The Axe-Fx II now uses 1024-point cabs in a stereo cab. This means that there's no signal degradation anymore when using stereo cabs.
Air and Drive
These Standard/Ultra parameters did not return in the Axe-Fx II.
