A -7 dB cut at 600 Hz with a wide Q creates the hollow mid-scooped character of dub techno chords

The recognizable ‘hollow’ quality of dub techno synth chords is created by aggressively cutting the upper low-mid / lower midrange frequencies, centered around 600 Hz, with a parametric EQ. A cut of roughly -7 dB with a wide Q (affecting a broad frequency band around the center) removes the nasal, boxiness of the midrange while leaving the lower lows and upper highs more intact. This scoop creates a recessed midrange presence that sounds spacious and distant — characteristic of the genre. Additional high-pass and low-pass cleanup above 4.5 kHz and below 100 Hz removes errant content at the extremes. The result is a sound that sits back in a mix and does not compete with the kick and sub-bass in the crucial low-mids.

Examples

Insert a parametric EQ after a synth chord patch. Add a bell curve cut at 600 Hz, Q set wide, gain -7 dB. High-pass at 100 Hz, low-pass at 4.5 kHz. Toggle the EQ bypass to hear how much the midrange scoop changes the perceived ‘hollowness’ and space of the sound.

Assessment

Given a spectrum display of a synth chord, identify which frequency region to cut for a dub techno hollow character. Describe the Q and gain settings and explain why a wide Q is preferable to a narrow notch for this application.
