When evaluating subwoofers in the professional audio industry, we avoid unnecessary gimmicks. Here are two practical yet highly accurate testing methods commonly used by our team:
1. Attach a tissue to the subwoofer grille: When low-frequency signals are played, observe whether the tissue fibers vibrate uniformly. Disordered vibration indicates poor transient response.
2. Place a half-full bottle of Nongfu Spring directly on top of the subwoofer: A fine, uniform ripple on the water surface is ideal, while violent splashing and constant shaking of the bottle indicate poor low-frequency control.
For the GRF unit tested today, the tissue does not drift disorderly, and only subtle, stable ripples appear on the water surface.
Remember this simple rule: No drifting tissue, no shaking water equals decent low-frequency performance.
