Here is the room response of the Proac Super Tablette monitor.  This was my main speaker (used with a Janus subwoofer) for many years, and I thought they were very uncolored in the midrange and imaged very well.  But -- the mid treble always seemed too hot.  The LAud plot shows that the tweeter voicing is definitely on the bright side, which probably intensifies whatever other problems the crossover may have in the mid treble.
