Key Features
The Tantrum Really Mean Sub is designed for engineers, producers and critical listeners who demand low-frequency accuracy in professional studio environments. Its feedforward 'Impulse Control' system uses predictive motion correction to eliminate driver overshoot, producing bass that's fast, defined and uncoloured.
Product Ref: 354804
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.
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.
The Really Mean Sub’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’s happening in your mix, even at higher monitoring levels.
Delivering 400W of ICEpower amplification, the Really Mean Sub provides ample headroom for demanding sessions while maintaining thermal stability and efficiency. Its sealed design ensures fast, controlled bass with minimal phase shift, ideal for small and medium-sized studios.
The Quick Alignment tool simplifies integration by automatically synchronising phase and timing with any monitor system. Compact yet powerful, it’s a refined subwoofer built to support critical decision-making in professional audio production.
