Amazing as it may seem, the Monitor Audio Gold FX's slim wall-hugging profile incorporates no fewer than six drivers. In monopole mode for discrete side or rear sound channels its front-firing 6 ½" RST® bass/mid-driver and C-CAM® ribbon transducer deliver accurate ultra-wideband sound to match the tonal balance of any 'Gold' speaker combination. In dipole mode the Gold FX uses two pairs of side firing 4" C-CAM bass/mid drivers and 25mm C-CAM gold-dome tweeters, combined with the tailored output from the front-firing bass/mid driver to provide wonderfully diffuse yet tonally precise surround effects. The Gold FX can be flush-mounted on side or rear walls. Installation is made easy by the inclusion of a 'sloppy fit' wall bracket, which allows levelling and adjustment prior to fixing. Supplied as single units.
