Cool, thanks CB  :thumb-up: . I've found I prefer the 2 x 12 setting, the 4 x 12 sounds a bit boxy

It's probably that dip the 2x12 setting takes at 500 Hz (vs. 600 Hz for the 4x12 setting).  The dip there seems to 'open up' the mids and adds clarity... think of Fender clean vs Marshall.  Fenders typically notch the mids lower than most higher gain amps/cabs... it's part of the 'clear' sound.  Having said that, I have a solid-state Fender from the '80s that dips at around 1 kHz and it's probably the best clean sound I've ever heard (Blackfaces and other tube amps included)... just 'big' and detailed sounding.  Which brings to mind something else...

The MP-2 2x12 emulation keeps the response down at just past 1 kHz and peaks at just over 2 kHz.  That's a classic recipe for clarity.  In fact, Boss has been using that recipe (down at 1+ kHz and peaking at 2+ kHz) for the 'enhance' feature on their bass limiter/enhancers and various multi-effects pedals since the late 1980s.  The old Boss LM-2B Bass Limiter/Enhancer dipped at 1kHz and peaked at 2kHz for the 'enhance' control, as did the Boss BE-5B and the modern ME series digital guitar and bass multi-effects units.

It's not only that 500 Hz dip, but also that the 4x12 is ~2 dB more up at 200 Hz and ~3 dB up at 300 Hz, which does bring about a decently more voluminous lower body.
While this 2-3 dB difference may not seem that much, still, when combined with the differences in the mid-scoop, it's no wonder that the 4x12 sounds decently darker - despite both emulation rolling of at the same 12 dB/octave and from the same frequency.

I must confess I had expected the high roll-off differences being more pronounced.
Good pspicing!  I must get back into such analysis at some point.

Oh BTW, it would be very interesting seeing a phase analysis; you know, how the phase changes over frequency can have significant impact on tone, even if amplitude levels don't change too much.
With this I'm thinking about how the filter circuit changes from 2x12 to 4x12 could produce different phasing  characteristics..
