SQ-Comp-Ref (Tight-Sub Edition)

Our own curve, developed in-house for this project. Blends deep-but-controlled bass with SQ accuracy: a deep sub-bass floor (+9.0 dB, similar to Audiofrog), a soft, ultra-smooth roll-off to 200 Hz (fully removes boominess), a presence dip (-2 dB at 2.5 kHz) and a natural HF roll-off (-0.5 dB/oct).

Flat

0 dB reference line — the neutral baseline. Useful for reading other curves' absolute deviation at a glance.
