speaker configuration question

[billyg121]

would it be possible to run 2-8ohm 1x12 cabs and a 2x12 cab with 2 -8 ohm speakers in it.....at the same time with the mark 4?

That'd be a 2-ohm total load. In terms of mismatch, the amp should be able to handle it fine, BUT it is also getting pretty close to '0' ohms.

If it were my rig I'd make up a box or cable that connected the two sets of speakers in series, for 8 ohms total.
