Perfection can take time

Krix speakers are usually made-to-order in South Australia, with construction beginning once your order has been placed. This process ensures great attention to detail is applied to each and every speaker, but it can also take time — sometimes around 2 weeks.

The phenomenal wall of sound from Krix.

Sits behind your acoustically transparent screen.


Key Features
- Behind screen cinema quality speakers
- Easy to install
- Krix Infinite Baffle Wall

Winner of the 2018 + 2017 Sound+Image Awards CUSTOM INSTALLATION PRODUCT OF THE YEAR

Designed for dedicated home cinemas with an acoustically transparent screen, the MX-20 will deliver your favourite movie soundtracks with supreme definition and accuracy, right through the picture and into your seat.

Experience Realism
For a wall of sound that plunges through the big screen, the MX-20 will provide the impact you’re looking for. With every aspect optimised to deliver the most faithful reproduction of movie soundtracks, from a whisper to the explosion immediately after, these modules provide a true commercial cinema experience at home.

The MX-20 is designed for cinema rooms four to seven metres long. This system comprises five modules, all of which are the same height and a slim line depth of just 295mm for simple installation into a wall cavity.

The main speakers feature a 255mm bass-mid driver which has a 50mm voice coil developed to offer low harmonic distortion, especially in the critical midband.

The high frequency drive unit is a damped, high power, 26mm doped fabric dome tweeter, coupled with a proprietary Krix waveguide, for optimum dispersion over the entire working bandwidth. Each subwoofer contains a large 380mm paper cone driver with a 100mm edge-wound copper voice coil, dual spider assembly, and vented magnet assembly.

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

Modular System
In a commercial cinema, sound is heard but not seen, with a wall of speakers driving the dynamic soundtrack directly through the big screen for the ultimate sound experience.

As leading developers of commercial cinema speakers, Krix delivers the cinema sound experience to your home cinema with Series MX. These unique modular behind-screen speaker systems, designed to be installed behind an acoustically transparent screen, will conceal everything but the cinema quality sound.

Combined with matching surround speakers, Series MX truly delivers the excitement, presence and impact of real cinema, at home.

The Krix Infinite Baffle Wall, which has been installed in commercial cinemas since the early 1980s, is also replicated in the MX series. The thick, acoustic absorption material on the front baffle of the speakers minimises reflections and prevents sound leakage behind the screen, for a high energy sound you can feel. For large or cinemascope screens, Krix’s optional low frequency absorption spacer modules can be used in pairs to ensure a wide, realistic soundstage.

Easy To Install
These speaker systems are designed to be installed behind an acoustically transparent screen, just like the speakers in a commercial cinema. They create a wall of sound directly from the picture, so everyone gets the full movie experience and impact. The five speaker modules (left, center, right and two subwoofers) in each system are all the same height and depth, making the design of the room and installation of the speaker system much simpler.

Control and Definition

These proprietary products have been developed by Krix over a 10 year period using powerful Finite Element Analysis (FEA). Krix patented horn technology provide exceptionally flat frequency response, precise pattern control, and very low distortion. Seamlessly coupled with the dispersion pattern of the woofer, the sound is focused on the audience and away from the walls, resulting in reduced reflections which can muddy the sound.

The specially engineered bass drivers are professional low frequency loudspeakers and offer superb bass performance, high peak program power handling and high efficiency, capable of extreme sound pressure levels. The smooth response, wide frequency and dynamic range are features not often achieved in one woofer. The bass drivers have an oversized ferrite magnet structure with components engineered to achieve maximum efficiency. Symmetrical gap geometry, combined with the large linear voice coil travel, ensures minimum distortion at all levels.

Cabinet Construction

Built from 18mm MDF with a black vinyl veneer, the cabinet is braced with Krix proprietary “X bracing”. This technique braces all the panels of the box in an asymmetrical way and also provides appropriate baffling to virtually eliminate standing waves in the enclosure and reduce panel vibrations.

Front Mount Concealed Terminals
Simply slide the modular system into its allotted space and connect the speaker cables into the special recess at the bottom of each enclosure, then replace the foam plug to conceal the cables.

Massive Dynamic Range
These cinema speakers are the real deal; the components and drivers are the same as those used in commercial cinemas. They are therefore efficient, powerful and reliable, and present a very easy load for the amplifier. Together with the Krix Infinite Baffle System they do not need large amounts of power to give you the full cinema experience.

Finished in 'Cinema Black'
Adorning all dedicated home cinema and commercial cinema speakers, this dark, stipple textured finish complements the true power within these mighty speakers.
