MXi-118 Infra-Bass Subwoofer

The Krix MXi-118 is designed to extend the home cinema experience beyond conventional bass reproduction, adding the scale, weight and tactile impact that bring modern movie soundtracks to life. Working alongside the Krix MX Series screen loudspeakers, the MXi-118 reproduces the deepest low-frequency effects with authority and control, allowing audiences to experience the physical sensation of sound as intended by the soundtrack creators. From distant thunder and spacecraft launches to the subtle pressure changes that create atmosphere and realism, the MXi-118 adds a new dimension to cinematic immersion.

Designed specifically for integration within high-performance home cinema systems, the MXi-118 can be installed behind acoustically transparent screens, incorporated into baffle wall constructions or positioned throughout the room as part of a distributed low-frequency system. Its flexible deployment options allow cinema designers to optimise low-frequency performance while maintaining seamless integration with the surrounding loudspeaker system. Whether supporting an MX-10, MX-20, MX-30 or MX-40 installation, the MXi-118 extends system capability without compromising the visual presentation of the room.

At the heart of the MXi-118 is a purpose-engineered 455mm (18″) driver featuring a large diameter voice coil, high-power motor assembly and long-excursion suspension system. Combined with a carefully tuned enclosure alignment, the design is optimised to reproduce frequencies that extend well below the operating range of conventional subwoofers. Rather than simply increasing bass output, the MXi-118 is engineered to extend system bandwidth into the infrasonic region, enabling the reproduction of low-frequency effects that contribute significantly to the realism, scale and emotional impact of modern cinematic soundtracks.

A defining characteristic of high-performance cinema loudspeakers is their ability to maintain consistent acoustic behaviour under demanding operating conditions. As playback levels increase, many low-frequency systems experience thermal compression, increased distortion and changes in response that can reduce impact and alter the character of the soundtrack. The MXi-118 has been engineered to minimise these effects through a combination of robust motor design, controlled excursion behaviour and efficient thermal management. By maintaining a more consistent transfer function across a wide range of output levels, the MXi-118 preserves low-frequency detail, dynamic impact and tactile realism whether reproducing subtle atmospheric cues or the most demanding infrasonic effects.

Krix MXi-118 Infra-Bass Subwoofer

The Krix MXi-118 is a high performance infra-bass subwoofer engineered for dedicated home cinema environments where deep low frequency extension, high output and precise control are essential.

Designed to integrate with Krix MX-30 and MX-40 cinema systems, the MXi-118 extends system performance into the infrasonic region, delivering the scale, pressure and physical impact found in commercial cinema environments.

Designed for Infra-Bass Performance

Using a high excursion 460mm 18-inch driver with massive displacement capability, the Krix MXi-118 is designed to reproduce extremely low frequency effects with authority and control.

With correct DSP integration, the MXi-118 is capable of extending down to 10Hz, allowing modern movie soundtracks to be reproduced with greater realism, weight and cinematic immersion.

Rather than simply increasing bass output, the MXi-118 enhances the entire home cinema experience by reproducing the low frequency energy and room pressurisation that conventional subwoofers often cannot achieve.

Flexible Home Cinema System Integration

The Krix MXi-118 infra-bass subwoofer is designed for flexible installation within dedicated cinema rooms, allowing system designers to optimise low frequency performance throughout the listening area.

Placement options include front wall, rear wall and side wall locations, supporting smoother bass distribution and improved consistency across multiple seating positions.

The MXi-118 can be integrated directly with Krix MX cinema systems or deployed independently as part of a larger high performance subwoofer system.

Reversible Cabinet Design

The Krix MXi-118 features a fully reversible cabinet with dual-terminal connectivity, allowing the subwoofer to be installed in either orientation without compromising performance.

This practical design provides greater flexibility when integrating the MXi-118 into MX-30 and MX-40 modular systems, or when positioning additional infra-bass modules throughout the room to improve bass consistency.

Engineered DSP Integration

To achieve maximum performance, the Krix MXi-118 requires an approved DSP amplifier capable of delivering the power, protection and low frequency control required for infrasonic reproduction.

Correct DSP configuration allows the MXi-118 to maintain controlled excursion, optimise transient response and deliver clean, powerful low frequency reproduction even at reference listening levels.

To experience the full performance of the Krix MXi-118 infra-bass subwoofer, contact CDA ProAV or visit our showroom for a professional home cinema demonstration and system consultation.

Engineered for High Output and Control

The MXi-118 uses a large format 460mm driver with a high power motor structure and long excursion capability, designed for low distortion at extreme low frequencies.

The sealed enclosure provides controlled response and integrates effectively with DSP-based system design, allowing precise management of infra-bass performance.

With recommended amplifier power in the 1500–3000W range, the system is designed for high output applications requiring both power and control.

Part of a Modular Cinema System

The Krix MXi-118 has been engineered as an integral part of the Series MX modular home cinema system. When combined with matching LCR loudspeakers and subwoofers, it extends system bandwidth into the infra-bass region while improving low-frequency consistency throughout the room. The result is a more balanced and immersive listening experience, with greater impact, realism and control.

The modular design allows multiple MXi-118 units to be incorporated into larger systems, providing additional infra-bass output where required while maintaining a consistent tonal balance across every seat. Whether used in a compact private cinema or a large dedicated theatre, the Series MX platform can be expanded to suit the room without compromising acoustic performance.

Visit the CDA ProAV showroom to experience Krix cinema sound for yourself and discover how the modular Series MX loudspeaker system can be tailored to deliver true commercial cinema performance in your home.
