    Introduction to the Krix MXi-118 Through-Wall Subwoofer<\/strong><\/h3>\n
    The\u00a0Krix MXi-118<\/strong> represents a paradigm shift in how high-end subwoofers are integrated into modern homes. Part of the renowned Krix Series MX family, the MXi-118 is engineered specifically for “through-wall” applications. This means the bulky cabinet is hidden in a room behind the theater (such as a garage or utility space), while only the high-output port and driver face enter the cinema room itself.<\/div>\n
    This unique configuration allows the\u00a0Krix MXi-118<\/strong> to move massive volumes of air without occupying valuable real estate inside your theater. It provides the same earth-shattering impact as Krix’s commercial cinema modules but in a format tailored for architectural perfection.<\/div>\n
    <\/div>\n

    Innovative Through-Wall Design Explained<\/strong><\/h3>\n
    Most high-performance subwoofers are difficult to hide because of their physical volume. The\u00a0Krix MXi-118<\/strong> solves this by utilizing the wall as a boundary. The enclosure is built to be mounted into a wall cavity or through a bulkhead.<\/div>\n

    Stealth Cinema Integration<\/strong><\/h4>\n
    By using the\u00a0Krix MXi-118<\/strong>, designers can achieve a completely “clean” aesthetic. There are no boxes on the floor and no visible cables. The speaker is finished with a baffle that can be covered by acoustically transparent fabric or custom cabinetry, making the source of the bass a total mystery to the audience.<\/div>\n

    Vibration Isolation<\/strong><\/h4>\n
    Krix has engineered the\u00a0Krix MXi-118<\/strong> with structural integrity in mind. The cabinet is constructed from 18mm and 25mm MDF with extensive internal bracing to ensure that energy is directed into the room, not into the wall structure, minimizing unwanted rattles and house-wide vibrations.<\/div>\n
    <\/div>\n

    The Engineering of the 18-Inch Driver<\/strong><\/h3>\n
    At the heart of the\u00a0Krix MXi-118<\/strong> lies a professional-grade 455mm (18-inch) driver. This isn’t just a large woofer; it is a high-sensitivity transducer designed for the most demanding cinema environments.<\/div>\n

    High Power Handling<\/strong><\/h4>\n
    The driver features a 100mm (4-inch) edge-wound copper voice coil on a high-power glass fiber former. This allows the\u00a0Krix MXi-118<\/strong> to handle sustained peaks of up to 1000 Watts RMS. This thermal stability ensures that during a 3-hour action movie marathon, the bass remains as crisp and impactful in the final scene as it was in the first.<\/div>\n

    Advanced Port Geometry<\/strong><\/h4>\n
    To support such a massive driver, the\u00a0Krix MXi-118<\/strong> uses a large, symmetrical vent system. This minimizes air turbulence and “chuffing,” ensuring that the subterranean frequencies remain pure and distortion-free.<\/div>\n
    <\/div>\n

    Acoustic Performance and Output Levels<\/strong><\/h3>\n
    The\u00a0Krix MXi-118<\/strong> is built for those who want to feel the soundtrack. In a typical residential room, a single unit can reach a maximum SPL (Sound Pressure Level) of 124dB.<\/div>\n
      \n
    • Subterranean Extension:<\/strong>\u00a0It reaches down into the infrasonic range, allowing you to feel the weight of deep atmospheric scores.<\/span><\/li>\n
    • Tactile Impact:<\/strong>\u00a0The sheer surface area of the 18-inch driver provides a physical “slam” that smaller subwoofers cannot replicate.<\/span><\/li>\n
    • Reference Accuracy:<\/strong>\u00a0Despite its power, the\u00a0Krix MXi-118<\/strong> remains articulate, making it equally capable of handling high-fidelity music.<\/span><\/li>\n<\/ul>\n

      Technical Specifications and Dimensions<\/strong><\/h3>\n
      The\u00a0Krix MXi-118<\/strong> is a substantial piece of equipment designed for professional integration.<\/div>\n

      Installation and System Integration<\/strong><\/h3>\n
      The\u00a0Krix MXi-118<\/strong> is a passive subwoofer and requires an external power amplifier with DSP capabilities.<\/div>\n
        \n
      1. Amplification:<\/strong>\u00a0We recommend a professional-grade amplifier capable of delivering 1000W+ into 8 Ohms to maximize the headroom of the\u00a0Krix MXi-118<\/strong>.<\/span><\/li>\n
      2. DSP Tuning:<\/strong>\u00a0Because the subwoofer is mounted through a wall, using DSP for room correction is essential to smooth out low-frequency peaks and nulls.<\/span><\/li>\n
      3. LCR Complement:<\/strong>\u00a0For the ultimate “Wall of Sound,” pair the\u00a0Krix MXi-118<\/strong> with Krix MX-30 or MX-40 main modules.<\/span><\/li>\n<\/ol>\n

        Frequently Asked Questions<\/strong><\/h3>\n

        Q: Do I need a professional to install the Krix MXi-118?<\/strong>
        A: Yes. Because it requires a significant wall opening and precise framing to support its 62kg weight, professional installation is highly recommended.<\/h4>\n

        Q: Can the Krix MXi-118 be painted?<\/strong>
        A: The baffle that faces the room can be finished or covered with acoustically transparent materials to match your decor.<\/h4>\n

        Q: Is the Krix MXi-118 better than a standard box subwoofer?<\/strong>
