I'm using the monitors just for music listening in a small living room (around 3,5m x 5,10m). The speakers and my sofa are placed in an equilateral triangle.
The speakers don't go very low, but the bass is very precise and taut, the midrange is excellent and the treble airy, detailed and without a hint of harshness.
Also, the instrument separation and timbre is spot on as well as imaging.
I listen predominantly to classical and some jazz (as well as some other genres) and these monitors just kill it.
Build quality is excellent as you would expect from Dynaudio and the DSP controls do come in handy, despite being placed on the back of the speakers.
