Barefoot Sound MasterStack12 4.5-Way Active Modular Monitor Tower (Pair)

The Barefoot Sound MasterStack12 is the ultimate expression of Barefoot’s monitor design philosophy—built for facilities that demand absolute accuracy, massive headroom, and uncompromising translation. As Barefoot’s flagship reference system, MasterStack12 delivers full-range monitoring down to infrasonic lows with exceptional control, making it equally at home in high-end mix rooms, mastering suites, and large-format immersive environments.

Flagship 4.5-Way Modular Design

MasterStack12 is a 4.5-way active modular tower system built from multiple sealed enclosures, combining ten total drivers per side into a single coherent reference. This architecture allows multiple woofers to work together at lower frequencies for reduced distortion and increased efficiency, while transitioning smoothly to fewer drivers at higher frequencies for improved dispersion and imaging accuracy.

• 4.5-way active modular tower monitor system.
• 3,500 watts of total amplification per side.
• Frequency response: 18 Hz – 50 kHz.
• Sealed cabinet design for precise transient response.

Dual-Force Low-Frequency Authority

Low-frequency reproduction is handled by eight 12-inch aluminum cone subwoofers per pair, arranged using Barefoot’s Dual-Force architecture. By mechanically coupling opposing drivers, cabinet vibration is cancelled at the source, allowing the system to deliver immense low-end output with clarity and control. Bass extension reaches down to 18 Hz, providing accurate reproduction of the lowest octave without port-induced artifacts.

• Eight 12-inch aluminum cone subwoofers per pair.
• Dual-Force vibration cancellation.
• Deep, controlled bass down to 18 Hz.

Reference-Grade Resolution Across the Spectrum

Above the subwoofers, three woofers, dual dedicated midrange drivers, and a precision ring radiator tweeter work together to deliver extraordinary resolution, dynamic range, and coherence. The result is a monitoring system that remains revealing at low listening levels and authoritative at concert-level SPLs, without sacrificing tonal balance or stereo imaging.

MEME Voice Emulation

MasterStack12 includes Barefoot’s MEME voice emulation, allowing engineers to audition mixes through multiple reference perspectives from a single monitoring position. These voicings are designed to reflect familiar translation references while preserving consistent imaging and room interaction.

• Flat: full-resolution Barefoot reference.
• Hi-Fi: enhanced warmth and polish for client playback.
• Old School: mid-forward voicing inspired by classic nearfields.
• Cube: mid-centric perspective for balance and translation checks.

Built for Large-Scale Studios

MasterStack12 is engineered for long-term reliability and integration into high-end control rooms. The modular tower design allows for optimized placement and decoupling, while optional handles and custom finishes provide flexibility for installation and aesthetic requirements.

• Available with or without handles.
• Optional custom Alpine White finish.
• Designed for high-SPL, full-range monitoring environments.
