I dont see how it can be since to do so the box would need to have
knowledge of (at least) your room acoustics and speaker properties, and
(preferably) the room characteristics the 'target' speaker is used in.

(on top of that you'd need a profile for the other speaker, of course.)

The assumption for that box, is that its driving either a clean PA, or a
desk, so it only needs to take into account the sound produced by
different speakers with different mikeing methods.

Remember we are not talking HiFi speakers here, the difference in sound
(for example) between a open backed AC30 and a closed Marshal 4*12 is
know and it does a good job of duplications. I don't own one, but have
played with one for some time. Its a useful box.
