1. Introduction to the Krix Megaphonix Centre In-Wall

When it comes to building a world-class home theatre, the centre channel is the most critical component. The Krix Megaphonix Centre In-Wall brings the raw energy of a commercial cinema directly into your home. This is not a standard architectural speaker; it is a high-sensitivity, high-output monster designed for dedicated theatre rooms.
Specifically engineered to fit within a standard 355mm (14″) stud wall cavity, the Krix Megaphonix Centre In-Wall allows you to have a massive, professional-grade speaker hidden behind your acoustically transparent screen or decorative fabric.

2. Key Features of the Krix Megaphonix Centre In-Wall

The Krix Megaphonix Centre In-Wall is packed with specialized features for the enthusiast:
    • Extreme Sensitivity: A 95dB rating means this speaker produces more sound with less power.
    • High-Impact Driver: Features a 255mm (10-inch) paper cone driver for deep, punchy mid-bass.
    • Rotatable Horn: The 90 x 40 degree horn can be rotated to suit horizontal or vertical installation.
    • In-Wall Integration: A slim 190mm depth ensures it fits into most wall cavities.
    • Cinema DNA: Uses the same components found in Krix commercial cinema speakers worldwide.

3. Why Your Cinema Needs a Dedicated Centre Channel

In any film, over 70% of the audio—including almost all dialogue—is delivered through the centre speaker. The Krix Megaphonix Centre In-Wall ensures that every whisper is crisp and every explosion is impactful. By using a high-pressure design, the Krix Megaphonix Centre In-Wall avoids the “thin” sound associated with typical in-wall speakers, providing a rich, full-bodied vocal presence.

4. The Science Behind Horn-Loaded Technology

The heart of the Krix Megaphonix Centre In-Wall is its proprietary short-throw waveguide. Traditional tweeters spray sound in all directions, causing reflections off the ceiling and floor that muddy the audio.
The Krix Megaphonix Centre In-Wall horn controls the dispersion, focusing the sound directly at the audience. This results in surgical precision and a soundstage that feels much larger than the room itself.

5. Technical Specifications & Performance Data

For those designing a high-end system, the Krix Megaphonix Centre In-Wall offers professional-grade stats:
    • Frequency Range: 40Hz – 20kHz
    • Power Handling: 50 – 250 Watts RMS
    • Sensitivity: 95dB (2.83V / 1m)
    • Impedance: Nominally 8 Ohms
    • Dimensions: 700mm High x 390mm Wide x 190mm Deep
    • Mounting Cut-out: 645mm x 335mm

6. Installation Requirements & Best Practices

To ensure the Krix Megaphonix Centre In-Wall performs to its full potential, consider the following:
    • Back Box: The Krix Megaphonix Centre In-Wall features an integrated back box to prevent sound leakage into other rooms.
    • Acoustically Transparent Screens: This speaker is ideal for placement behind a woven or micro-perforated projector screen.
    • Positioning: Install with the horn at ear level for the most immersive experience.
    • Amplification: While sensitive, it thrives on high-quality external power amplifiers.

7. Frequently Asked Questions (FAQ)

Can I use the Krix Megaphonix Centre In-Wall as a Left or Right speaker?
Yes. Since the horn is rotatable, the Krix Megaphonix Centre In-Wall is often used as a matched LCR (Left, Centre, Right) set for total tonal consistency.

Does it require a subwoofer?
While it has great mid-bass, we recommend pairing the Krix Megaphonix Centre In-Wall with a Krix Cyclonix or Volcanix subwoofer to handle sub-20Hz frequencies.

Is the baffle painted?
The speaker comes in a professional “Cinema Black” finish, designed to disappear behind a screen or fabric wall.

8. Why Choose Krix Audio?

Krix is a world-leader in cinema sound. When you invest in a Krix Megaphonix Centre In-Wall, you are buying 40 years of Australian research and development.
