Band: opinion spread · Dot: weighted average
Sources split, with the weight on the neutral side. AUDIO magazine's lab found the response straight apart from a small dip at 1 kHz, a hobbyist's 1 m outdoor sweeps found it flat, and Les Numériques and bonedo call it neutral — bonedo on a 1 m triangle. Amir measured it as reasonably flat on-axis but found colorations he could only partly fix with EQ, and a group of owners — on Thomann, Sweetwater and ASR — hear it as harsh, analytical or mid-forward. Higher Hz hears the opposite shape, a "smiley face" with hyped highs and scooped lower mids.
Measured
Klippel NFS (ASR, spinorama.org): listening window within ±2.3 dB from 300 Hz to 5 kHz; preference score 5.85 without a subwoofer (7.58 with an ideal one, 6.78 with its automatic EQ). Amir notes woofer and tweeter resonances and a predicted in-room response made uneven by limited directivity control. AUDIO magazine (2017): straight response apart from a small dip at 1 kHz. Average Joe Audiophile's close-mic and 1 m outdoor sweeps: flat, with a slight rise above 7 kHz.
vs. listeners — On-axis the lab data is close to flat. Amir notes that its limited directivity control makes it room-dependent, and ASR members trace its loud highs to the directivity mismatch above 2 kHz — so how harsh it sounds depends partly on the room.
“Ce sont de très belles performances que nous offre ce couple de HS8 avec une régularité exemplaire dès 300 Hz”
Benoît Campion, Les Numériques ("a pair that performs very well, exemplary evenness from 300 Hz up")
“This is complex level of colorations which is harder to diagnose and correct.”
Amir, Audio Science Review
