We are giving you the chance to win a complete monitoring solution from Tantrum Audio, worth £1640$2494 in total!
Single-driver monitor speakers have a proud history in the recording studio, and last year, British company Tantrum Audio brought the concept bang up to date with their Angry Box speakers. A world apart from the low-tech monitors of old, the Angry Box boasts 65 Watts of Class‑D amplification and an Analog Devices digital signal processor, allowing the user to switch between an old‑school ‘mid focus’ mode and a high‑fidelity ‘extended bandwidth’ mode, which significantly extends its frequency response to compete with conventional two‑way speakers — essentially giving you two monitors in one.
When Mike Senior reviewed the Angry Box in SOS November last year, he found it to be “extremely effective at clarifying critical questions of midrange balance” in mid focus mode, while the extended bandwidth setting made them a unique tool in the professional monitor market.
Further refining the Really Mean Sub’s performance is an integral DSP engine, which both automatically integrates the sub with your full‑range monitors, and performs full room correction for both the subwoofer and your full‑range monitors.
The Prize
For this exclusive SOS competition, we’re giving you the chance to win the Tantrum Audio Angry System: a complete monitoring solution comprising a pair of Angry Box monitors and the company’s brand‑new subwoofer, the Really Mean Sub.
The Really Mean Sub is based around a pair of super‑fast, high‑excursion, 6.5‑inch woofers powered by a 400W ICEpower amplifier — a combination that yields a mighty LF extension of 15Hz at the -10dB point (and only a single decibel down at 28Hz). Maximum SPL is an ample 102dB, while the sub’s sealed‑box architecture means it doesn’t suffer from the resonances and pitch uncertainties that can afflict ported subs.
Further refining the Really Mean Sub’s performance is an integral DSP engine, which both automatically integrates the sub with your full‑range monitors, and performs full room correction for both the subwoofer and your full‑range monitors. The result, say Tantrum Audio, is “tight, phase‑coherent bass that feels like a natural extension of your monitors — not an add‑on”.
