I just listened to the Borresen X2 Model (2.5 way towers) and on familiar program material they sounded really, really nice. Bass was clean, clear and well defined, midrange and treble were like an open window the sound was so clear.
My only concern was the imaging which I will need to revisit before buying them. The center image seemed to shift away from the center at random times. Possibly not the best toe angle for the broadest sweet spot. Regardless these are seriously good sounding speakers and nothing to scoff at before hearing them.
