Really?  I thought it just listened to the output and calculated a boost as a percentage of the input, i.e. you could be driving cardboard (or flax!) with tubes, for all the DSP algorithm cared.  This is how Dirac Live can work inside a MiniDSP DDRC-24 (e.g.): Dirac knows nothing about the speakers or the amp, only what it hears from its microphone input when it sends out a known signal sweep.

And “speaker elements” == “drivers” colloquially so yes, s/he is indeed hooking up the inexpensive Symfonisk amp to the 4000’s drivers and bypassing or removing the electronics.  BeoWorld description claims 35 watt x 2 (ICEpower version mk.2), and supposedly the amplifier on the Symfonisk speaker is the TI TPA3116D2, a two channels x 30 watts per — so it could work OK unless you crank the volume up, maybe? [Edit: the DSP will take some headroom too.]
