Krix MXi-118 Infrasonic Subwoofer Module for MX-30/i, MX-40/i

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.

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.
