CB-X12 Active Subwoofer
MAG Theatron CB-X12 Active Subwoofer
The CB-X12 delivers fast, controlled, and profound bass with active DSP processing, designed as a core block for distributed multi-subwoofer cinema systems.
Overview
The MAG Theatron CB-X12 Active Subwoofer is designed for cinema rooms that demand both impact and consistency at every seat. Built as a precision closed-box design with heavy internal bracing, it combines a long-throw 12-inch driver and a 1200W class D amplifier with onboard DSP. MAG positions the CB-X12 as the heart of a Multi Subwoofer System (MSS), where several units are placed strategically and tuned independently with delay and EQ to reduce standing-wave artifacts and improve seat-to-seat bass uniformity. Its infrasonic extension and high linear excursion support tactile low-frequency pressure while maintaining control and articulation. Alongside its performance focus, the CB-X12 platform is offered in premium finish options to suit high-end room design language.

Integrating MAG Theatron CB-X12 in Cinema Projects
At Kolosseum, CB-X12 is deployed as part of engineered multi-sub layouts where each unit is time and EQ aligned independently for smooth seat-to-seat bass behavior.
Room Requirements
Best suited to dedicated cinema rooms where two or more subwoofer positions can be planned early in the design stage.
Recommended Screen Pairing
Typically paired with high-output LCR screen systems and integrated via processor-managed bass management and delay alignment.
Acoustic Considerations
For MSS use, we optimize placement first, then apply per-sub delay, phase, and EQ to reduce modal peaks/nulls and maximize low-frequency uniformity.
