Really Mean Sub – Precision Powered Subwoofer
Looking for bass that doesn’t flatter your mix? The Really Mean Sub is your brutally honest low-end companion — built to expose issues, not hide them.

Purpose-Built Transparency
The Really Mean Sub is designed to spotlight weaknesses in your mix’s low end. Whether you`re pairing it with the Angry Box or other studio monitors, it reveals the truth down to the deepest frequencies.

Tight, Controlled Bass
Featuring dual-opposing, mechanically coupled drivers, the enclosure is built from 24 mm MDF to drastically reduce vibration and intermodulation distortion. This keeps your low-end focused, clean, and punchy — even at louder playback levels.

The built-in 400 W ICEpower amplifier ensures consistent performance with a maximum SPL of 102 dB, and a frequency response reaching as low as 15 Hz (-10 dB).

Smart DSP Integration
With USB-C control and advanced DSP, the subwoofer allows for:
• Built-in crossover management
• Quick Alignment timing sync
• Footswitchable sub mute and crossover bypass
• ±3 ms adjustable time delay
• Beta-stage intelligent room correction

This enables seamless integration with a wide range of monitoring setups.

Compact Yet Capable
Despite its small footprint (just 28 cm cubed and 20 kg), it delivers a powerful and extended low-frequency response from 28 Hz to 200 Hz (±1 dB). Ideal for studios where space is tight but sonic accuracy is essential.

Designed & Built in the UK
From its high-quality electronics to its robust build, the Really Mean Sub is engineered and manufactured in the UK, offering both premium performance and long-term reliability.

Why Choose the Really Mean Sub?
• Honest, revealing low-end response
• Excellent transient accuracy thanks to impulse correction
• Low distortion design for true-to-source playback
• Easy integration with existing systems
• Footswitch controllable and USB-C configuration for flexible workflow

Summary
The Really Mean Sub isn’t just about more bass — it’s about better bass. It gives you the low-end truth, exposes mix issues, and lets your tracks hit harder without hype. If you`re ready to take your monitoring to a more honest place, this subwoofer is ready to show you what your mix is really made of.
