Band: opinion spread · Dot: weighted average
Sources split. Most — napilopez's measurement, Sound On Sound ("certainly very low" coloration), MusicRadar, Soundphile, Digital Trends, Wired, Crinacle and several owners — hear a close-to-neutral balance for the size. A sizeable minority hear colour: NoAudiophile measured and heard an elevated 2 kHz region that makes it sound hollow, a DCinside measurer reads a slight V-shape, and some owners on Amazon, Thomann, ASR and Reddit call it nasal, plasticky or "decidedly NOT flat".
Measured
Quasi-anechoic spin (napilopez, 1 m, gated, 2020): broadly flat on axis with three deep, narrow dips napilopez traces to port cancellations (the worst near 600 Hz) and a shallow scoop around the 3 kHz crossover; spinorama.org's preference score from that data is 3.83 (6.12 with an ideal sub). NoAudiophile (2017, outdoor windowed + ground plane): a 2 kHz bump in every measurement and a 15 kHz peak. DCinside (Nuyes, 2021): a slight V-shaped response.
vs. listeners — The two English-language measurements disagree: NoAudiophile's 2017 unit shows a 2 kHz peak and no 3 kHz dip, napilopez's 2020 unit the reverse, with different rear switches — both suspect an unannounced change. Early reviews describe a −3 dB treble switch; IK's current spec lists 0/+2 dB. Which production run you get may explain part of this split.
