“Massive performance”

The Megaphonix In-Wall Centre is designed to be installed below televisions or non-acoustically transparent projector screens. Using high power handling and high sensitivity drivers, these speakers will deliver crystal clear dialogue and dynamic effects, for a real home cinema experience.


The 255mm bass driver has a 50mm voice coil and has been developed to offer low harmonic distortion, especially in the critical midband. The paper cone and surround of the bass driver have been developed to provide the smoothest possible response. The high frequency drive unit is a specially-damped, high power, 26mm doped fabric dome tweeter, and is coupled with Krix’s proprietary waveguide to provide consistently-maintained optimum dispersion of 90 degrees horizontal and 40 degrees vertical over the entire working bandwidth.


The combined high frequency response is exceptionally smooth and well controlled – a new benchmark in loudspeaker reproduction.


Finished with a powder coated steel front baffle for easy installation, the Megaphonix In-Wall Centre is the perfect answer for a concealed, horizontal installation while maintaining exceptional performance.


For the ultimate cinema experience at home, play it through Krix.

For a real ‘cinema sound’ at home, it makes sense to use similar technology to the real thing, to get the experience as close as possible. But why compromise on ‘close’? The Krix Series SX range is the real thing, scaled down to fit within the constraints of the home. It proved monumental in its ability to deliver soundtracks at full throttle, yet delicate and sophisticated enough to play music at the heights of realism. Simply superb.
