Tantrum Audio Angry Box Stereo Studio Monitors in Black

The Tantrum Audio Angry Box Stereo Studio Monitors in Black are ultra-compact, point-source reference cubes designed to tell you the truth about your mix. With DSP-controlled linear and mid-focus modes, sealed enclosures and full-range drivers, they deliver brutally honest midrange detail, lightning-fast transients and stereo imaging that feels almost holographic, all in a footprint small enough to live anywhere in your studio.

Whether you are mixing, producing, editing or building an immersive Dolby Atmos rig, Angry Box monitors are built to be your no-nonsense reality check. Flat in phase and frequency response within their working band, they reveal every transient, every vocal nuance and every flaw, helping you make decisions that translate effortlessly to real-world playback systems.

True Point-Source Monitoring

At the heart of the Angry Box is a single 4.5 inch full-range driver in a sealed 14 cm cube, giving you a genuine point-source design. With all frequencies emanating from one physical point, stereo imaging becomes razor sharp and time alignment is inherently precise. Panning, depth and placement are easier to judge, and multi-speaker or immersive setups benefit from consistent behaviour across every unit.

Linear and Mid Focus DSP Modes

An integrated Analog Devices DSP flattens both phase and frequency response, then lets you choose between full-range clarity and a focused midrange mode. Full Range mode gives you a fast, linear reference that still feels musical, while Mid Focus narrows the response to the critical 90 Hz to 12 kHz band where vocals, guitars and most mix decisions live. It is like having a modern alternative to classic NS10 and Auratone-style references at the flick of a switch.

Fast, Sealed and Unforgiving

The sealed enclosure and single driver combination delivers exceptional transient response and time-domain behaviour. Kicks, snares and percussive details start and stop with surgical precision, while the honest low-end roll-off mirrors how many real-world systems behave. Instead of flattering your mix, Angry Box monitors expose problems in your low mids and midrange so you can fix them before they show up on streaming platforms, laptops and small speakers.

Built for Modern Stereo and Immersive Rigs

With compact dimensions, balanced XLR and TS inputs, and a conical 110 degree dispersion pattern below 4 kHz, Angry Box monitors are easy to position in tight spaces and complex setups. They are designed to partner with Tantrum Audio's Really Mean Sub for extended low end, and their point-source behaviour scales from a simple stereo pair to full Dolby Atmos and immersive arrays, making a serious multi-channel monitoring environment far more attainable.

• True Point-Source Design - A single 4.5 inch full-range driver in a sealed cube means sound comes from one point in space, improving time alignment and stereo imaging. This makes panning decisions more intuitive and ensures consistent behaviour across multiple speakers in surround or immersive setups.
• DSP-Controlled Linear and Mid Focus Modes - Onboard Analog Devices DSP delivers a flat, phase-coherent response and lets you switch between full-range monitoring and a mid-focused mode. You can check translation in the crucial vocal and guitar band without changing speakers, speeding up mix decisions and reducing guesswork.
• Ultra-Compact Sealed Enclosure - Measuring just 14 x 14 x 14 cm with a sealed cabinet, the Angry Box offers fast, controlled transients and an honest low-end roll-off. The tiny footprint makes it easy to place on crowded desks, meter bridges or stands, even in small rooms or complex Atmos rigs.
• Honest, High-Output Monitoring - With 65 W of Class D amplification and a 102 dB peak SPL, the Angry Box delivers plenty of level without sacrificing accuracy. Advanced speaker protection helps maintain long-term reliability, so you can work confidently at realistic mix volumes while still hearing every detail and imperfection in your recordings.
