Before the points to be criticized are addressed, first something positive about the radiation of the loudspeaker.
Between 600Hz and 8kHz the HR5 shows good CD behaviour. The 70° frequency response measurement is almost parallel to the axis frequency response.
Unfortunately, the frequency responses below 70° horizontally radiate a bit too much sound power in the range 3-9kHz and above 8kHz too little.
This imbalance is corrected by the axis frequency response with a wide dip between 3kHz and 9kHz and above 9kHz the 5dB boost overcompensates a bit.
The sound was rather harsh.
I can't say for sure if it's just the (especially horizontal) radiation, but I had the same listening experience with a similar (slightly wider radiating) loudspeaker. Especially tightly struck cymbals sounded very aggressive (because of the sound power in the 5-7kHz range?). That sound was not for me.
For comparison, here are the normalized measurements (Peerless HDS830990 with ScanSpeak 851100):
I would like to pick out another unusual point, the bad decay behavior around 800Hz. After 10ms, or eight oscillation periods, the resonance has only decayed by 17dB.
My guess is that the resonance is caused by the diffraction slit in front of the 7'' chassis or that a surround resonance is amplified by it. Since the resonance slightly changes the pitch as it decays, according to the measurement, I would consider this relevant in this case, since the damping after 10ms is just -17dB.
