The Pinnacle of Stealth Cinema: Krix MX-40i Modular
The Krix MX-40i Modular represents the absolute zenith of in-wall architectural audio. While most hidden speakers compromise on scale, the Krix MX-40i Modular is a no-holds-barred powerhouse designed for large-scale, premium home cinemas.
By utilizing a 5-module configuration that recesses into your wall cavity, the Krix MX-40i Modular provides the visceral impact of a commercial theatre without occupying a single inch of floor space. It is the perfect marriage of aesthetic invisibility and acoustic dominance.
The 3-Way Advantage: Precision Midrange Clarity
What truly separates the Krix MX-40i Modular from other systems in the Series MX range is its sophisticated 3-way design.
Dedicated Midrange Performance
Unlike 2-way systems where the woofer handles both bass and vocals, the Krix MX-40i Modular features a dedicated 165mm (6.5″) midrange driver. This allows for startlingly realistic dialogue and a more nuanced soundstage. When you listen to the Krix MX-40i Modular, every breath and subtle foley effect is delivered with surgical precision.
Controlled High-Frequency Dispersion
The high-frequency unit in the Krix MX-40i Modular uses a 25mm fabric dome tweeter coupled with a specialized Krix waveguide. This ensures that the sound is focused directly at the audience, minimizing wall reflections and maximizing clarity.
Flagship Performance: Dual 18-Inch Subwoofers
At the base of the Krix MX-40i Modular power are two massive 455mm (18″) subwoofers. These are high-displacement, professional-grade drivers designed to reproduce low-frequency effects (LFE) with tectonic force.
The Krix MX-40i Modular doesn’t just play bass; it creates a physical experience. Whether it is the low rumble of a spaceship or the sharp crack of an explosion, these 18-inch drivers ensure that your cinema experience is felt as much as it is heard.
Infinite Baffle Technology for In-Wall Applications
The Krix MX-40i Modular utilizes Krix’s proprietary Infinite Baffle technology, adapted specifically for flush-mount installations. Each module’s front face is covered in high-density, sound-absorbent material.
This design creates a solid acoustic plane that prevents sound waves from wrapping around the speaker and reflecting off the rear wall. With the Krix MX-40i Modular, phase cancellation is eliminated, resulting in a cleaner, punchier, and more efficient soundstage than any traditional in-wall speaker could provide.
Modular Design: Customization for Massive Screens
The “Modular” aspect of the Krix MX-40i Modular is vital for ultra-wide screen setups (CinemaScope 2.35:1 or 2.40:1). Because the LCR and Subwoofer modules are separate, you have the freedom to space them according to your screen’s width.
This ensures that the audio for the Krix MX-40i Modular tracks perfectly with the action on screen, providing an authentic “Voice of God” effect where the sound emanates directly from the actors’ mouths.
Technical Specifications & Installation Requirements
Because of its massive scale, the Krix MX-40i Modular requires specific structural considerations:
- Cavity Depth: A minimum depth of 335mm is required to house the modules.
- Biamplification: The LCR units of the Krix MX-40i Modular are designed for bi-amp or tri-amp configurations for ultimate control.
- Screen Type: Use only a high-quality acoustically transparent screen to allow the Krix MX-40i Modular‘s detail to shine through unimpeded.
Frequently Asked Questions
Is the Krix MX-40i Modular too powerful for a medium room?
The Krix MX-40i Modular is optimized for rooms 6m and longer. In smaller spaces, the headroom ensures effortless sound, but for maximum efficiency, the MX-20 or MX-10 may be better suited.
Does the Krix MX-40i Modular come with grilles?
No. Since the Krix MX-40i Modular is designed to be installed behind a screen or acoustic fabric wall, it features a specialized “Cinema Black” finish to prevent light bounce.
