Barefoot Sound MasterStack12 12-Inch 4.5-Way Active Studio Monitor Pair

Barefoot Sound MasterStack12 12-Inch 4.5-Way Active Studio Monitor Pair

The Barefoot Sound MasterStack12 12-inch 4.5-way active studio monitor is the pinnacle of Barefoot Sound's engineering achievements — a 4.5-way active modular tower monitor housing ten drive units across two cabinets per channel: a 1-inch ring radiator tweeter, two 2.5-inch aluminum cone midranges, three 6.5-inch aluminum cone woofers, and four 12-inch aluminum cone Dual-Force™ subwoofers — powered by 3,500W of Hypex amplification per tower, with bass extension to 18Hz and a ±3dB window spanning 18Hz to 50kHz that represents the absolute state of the art in professional studio monitoring. As a result, mastering engineers, recording studios, and post-production facilities who demand the ultimate reference monitoring system gain a modular tower that delivers SPLs equivalent to the largest main monitors in any room size, with the compact sealed-cabinet accuracy, transient speed, and MEME™ voice emulation versatility that define the Barefoot Sound platform. The 4.5-way designation reflects the system's sophisticated woofer architecture: all three 6.5-inch aluminum cone woofers operate together in the lower portion of the woofer band, where having three drivers working in parallel reduces distortion through greater efficiency and collective excursion capability; at higher frequencies, the crossover transitions to just two woofers, whose narrower combined dispersion pattern matches the increasingly directional nature of sound in the upper woofer band before handing off to the midranges at 200Hz. The four 12-inch Dual-Force™ subwoofers are driven by a combined 2,400W Hypex subwoofer amplifier, achieving ±25mm linear excursion per driver with locked opposing motor pairs that physically cancel vibration before it can reach the 180-litre sealed cabinet — the most powerful implementation of the Dual-Force™ system Barefoot Sound produces. In addition, MEME™ technology provides four reference voicing modes (Flat, Hi-Fi, Old School, and Cube), the MasterStack12 is available with or without handles, and a custom Alpine White finish is available as an option for studios where the standard Barefoot Black finish does not suit the aesthetic. OneStopMusic South Africa stocks the Barefoot Sound MasterStack12 12-inch 4.5-way active studio monitor pair for South African mastering studios, professional recording facilities, and post-production houses who require the absolute flagship of Barefoot Sound's reference monitoring lineup.

The Flagship of Reference Monitoring — Barefoot Sound MasterStack12 12-Inch 4.5-Way Active Studio Monitor

Whether you're mastering the most demanding commercial releases, running the main monitors in a world-class recording studio, or building a professional monitoring system that will serve as the definitive reference for decades of creative work, the Barefoot Sound MasterStack12 12-inch 4.5-way active studio monitor represents the highest achievement in professional studio monitor design. The 18Hz bass extension — two full octaves below the –3dB point of many "full-range" monitors — reveals sub-bass content in recordings that other monitoring systems simply cannot reproduce at any level of accuracy, enabling mixing and mastering decisions in the lowest octave that translate reliably to cinema systems, home theatre subwoofers, and club sound installations. The three-cabinet modular architecture allows each MasterStack12 tower to be positioned, decoupled, and installed with a degree of flexibility that monolithic large-format monitors cannot achieve, while the optional third enclosure for signal and power distribution can function as a decoupling base unit beneath each tower. However, the MasterStack12's defining quality — beyond any individual specification — is its coherence: ten drive units, a 4.5-way crossover, and 3,500W of Hypex amplification working together in a DSP-optimised system that Barefoot Sound has dedicated thousands of development hours to perfecting, producing a seamlessly integrated soundstage that reveals the truth in recordings with an honesty no other monitor in its class can match. OneStopMusic South Africa recommends the Barefoot Sound MasterStack12 12-inch 4.5-way active studio monitor pair to South African mastering engineers, world-class recording studios, and professional post-production facilities who demand the ultimate flagship reference monitoring system available.
