Monitor Audio Bronze BX-FX Speaker (Black Oak)
One pair of BX-FX speakers in black oak
The versatile BX-FX dual-mode surround speaker adds the facility to switch dispersion for side or rear channel use, allowing the BX-FX to optimise five or seven channel systems. Utilising a single 140mm (5 1/2") C-CAM® bass/mid-range driver flanked by two 25mm (1") C-CAM® tweeters on angled baffles, the super-compact BX-FX is easy to position for amazing surround effects and is available in the BX range of finishes for a closer décor blend.
Features
- Acoustically matched with all other BX loudspeakers for excellent surround sound imaging and consistent timbre.
- Switchable dual-mode design for direct or ambient sound.
- New C-CAM® tweeter has greater sensitivity and a wider bandwidth beyond 30kHz.
- New C-CAM® bass and mid-range drivers refined by FEA analysis.
- Single bolt-through drivers. A design feature which means the driver is not fixed to the front baffle and cannot transmit vibrations and therefore coloration to the cabinet.
- Improved cabinet rigidity and stability.
- High-quality terminal panels blend easy access with high-end functionality.
- Choice of two high quality vinyl wood finishes.

Technology
C-CAM® Drivers: Ceramic-Coated Aluminum/Magnesium is a material originally developed by the aerospace industry for jet engine components. Its properties are ideal for loudspeaker cones being extremely rigid, yet light enough to yield high overall efficiency. In manufacture, aluminum/magnesium alloy undergoes a three-stage stress-relieving process to remove surface deformation and molecular weakness. Once formed, the alloy cone is subjected to a high temperature anodic coating process in which a layer of pure ceramic alumina is depleted onto its surfaces to a depth of 50 microns, producing a completely rigid sandwich of alloy and heat-dissipating ceramic material.
Conventional cones are liable to flex or twist in operation, producing a significant level of audible distortion. C-CAM cones have a much higher resistance to bending stress and therefore exhibit much greater fidelity over their entire operating range. C-CAMtweeters and woofers share an audible consistency producing a smooth transition of frequencies and a sense of realism and cohesion in the soundstage.
Gold Dome C-CAM®: The gold dome tweeter is formed from a ceramic-coated aluminum/magnesium alloy, gold anodized to a specific thickness for ideal stiffness and damping characteristics. Its new profile and surround geometry have been developed using advanced modeling tools, to provide the optimum qualities for accurate sound reproduction. The new design moves the first order of breakup to beyond 35kHz, producing a linear response way beyond audibility, which matches the wide frequency bandwidth available from HD music and cinema sound formats.
The gold dome is thinner, lighter, more rigid and therefore more efficient than domes made from other materials which are prone to distortion in the audio band.
