Barefoot Sound MasterStack12 4.5-Way Active Monitor Tower - Pair

4.5-way active modular tower monitor with MEME Technology - optional handles not included
MFR# MasterStack12

Product Description

The Barefoot Sound MasterStack12 is Barefoot’s most advanced monitoring system to date. This astonishing modular monitoring tower combines an innovative 4.5-way active design with 10 state-of-the-art drivers, advanced DSP technology and nearly 3,500 total watts of power for unparalleled performance. The MasterStack12 is ideal for large format studios, and is the leading choice for professional audio engineers and producers around the world, including Chris Lord-Alge, Skrillex and more.


In a typical 4-way system, the subwoofers, woofers, mid-range drivers and tweeters all operate within their own designated frequency range. But Barefoot’s cutting-edge 4.5-way design uses different frequency ranges for each woofer to deliver a more even and balanced sound. All three woofers extend down to 80 Hz for extremely efficient low-frequency response. However, only the two woofers in the top enclosure extend all the way up to 200 Hz, which creates a smooth transition to the more directional high frequencies.


The MasterStack12 features a modular tower design with 10 drivers spread across two cabinets, as well as a third enclosure for signal and power distribution. Four 12-inch aluminum cone subwoofers with Dual-Force technology deliver earth shattering subs for to 18 Hz. Three 7-inch woofers work together to provide rich, deep lows, while two 2.5-inch midrange drivers offer plenty of detail and clarity. Finally, a 1-inch dual ring radiator tweeter delivers super-smooth highs all the way up to 40 Hz.


All Barefoot Sound studio monitors are equipped with Multi-Emphasis Monitor Emulation, or MEME technology, which uses sophisticated DSP processing to emulate the sound of a wide range of classic studio monitors. Quickly reference your tracks on three additional monitor profiles and ensure your mixes will translate to any environment.

“Old School” mode emulates the sound of the iconic Yamaha NS10M monitors with an edgy, midrange-forward sound. The “Cube” setting is modeled after the legendary Auratone Sound Cube, giving your mixes a boxy, lo-fi sound. On the opposite end of the spectrum, the “Hi-Fi” setting emulates the sound of consumer hi-fi systems with a sweet high-end and warm midrange. And of course, the “flat” setting delivers the signature Barefoot sound that engineers, producers and musicians around the world have grown to know and love.

Over a decade ago, Thomas Barefoot applied his expertise and experience as an engineer, scientist and inventor in the computer industry to his lifelong passion for music. Approaching the pro audio industry with a fresh pair of eyes, he concluded that every project would benefit from using monitors with the same sound quality, dynamic range and bass extension at each stage of the production process. The innovative reference monitor designs that Thomas subsequently developed not only deliver the same performance and quality from recording through mastering, they also turned the studio monitor speaker business on its head, outperforming many well-established high-end products.

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.

From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
