| Frequency Range | Behavior | Perceptual Effect | | :--- | :--- | :--- | | | Moderate roll-off, slight boxiness | Lacks sub-40Hz concert grand rumble; feels more like an upright. | | Mid (250 Hz - 2 kHz) | Preserved; slight dip at 1 kHz | Clear harmonic content for pop chords; avoids harsh "digital" peaks. | | High (> 4 kHz) | Gentle low-pass filter at 12 kHz | Reduced key noise and pedal thumps; creates a softened, tape-like top end. |
