Product Description
- Feedforward impulse control enhances transient accuracy Traditional subwoofers often struggle with overshoot causing low-end smearing and a loss of definition. The Really Mean Sub employs a feedforward Impulse Control system that anticipates driver motion and prevents it from exceeding its natural limit. By addressing excess excursion before it occurs the system preserves phase integrity and transient clarity. This allows you to evaluate kick bass and subharmonic content with confidence maintaining accurate low-frequency translation across playback systems. Integrated DSP for precision system alignment The onboard USB-C DSP platform provides detailed configuration for room correction crossover and phase alignment. Engineers can fine-tune subwoofer behaviour to compensate for specific room modes and achieve a perfectly balanced low-frequency response. With processing available on both sub and main outputs the system ensures consistent tonal coherence through class-AB output stages. This helps you maintain the intended mix balance without relying on external correction tools or guesswork. Dual-opposing drivers for ultra-low distortion The Really Mean Sub&rsquo
- s dual-opposing driver design operates in mechanical opposition effectively cancelling reactive forces within the enclosure. This configuration significantly reduces structural vibration and intermodulation distortion preserving detail and improving transient accuracy. Combined with a sealed 24mm MDF cabinet the result is tight responsive bass reproduction that accurately reflects what&rsquo
