The ultra-compact Gold C150 centre speaker is small enough to fit into most AV racks and is designed to match the smaller Gold speakers in a more bijou home theatre configuration. However, because it shares tonal characteristics with all models, its capabilities are also compatible with any 'Gold' system design. The Gold C150's lustrous sealed cabinet is home to twin 5.5" drivers and the ribbon in a two way orientation, providing superior dispersion across a range from 50Hz to 60kHz.
Purer and more bewitching than ever, our latest Gold range refines the technology of its award-winning GX predecessor to set a new gold standard for our celebrated high-end speaker line. Equipped with optimized drivers and empowered by the production quality of our world-beating Platinum flagship range, gilt-edged Gold turns another page in the story of Monitor Audio’s audiophile speaker family.
Developing the legacy of three award-winning generations, eight new dedicated stereo, center channel, surround and subwoofer models share a trinity of enhancements including an evolution of the C-CAM Rigid Surface Technology (RST) bass cone employed by their Gold GR and Gold GS predecessors; tighter production tolerances for their advanced C-CAM ribbon tweeters, and a smarter more functional grill design. Energized by these upgrades our new Gold range offers greater transparency, consistency and visual sophistication to devotees of sound and style everywhere, leaving you simply to choose the system that’s right for your room.
The Gold series ribbon is derived from the globally acclaimed Platinum C-CAM ribbon transducer. Mechanically it’s identical to the GX ribbon but by improving production tolerances even further, we’ve discovered that the new model offers a consistently more open and transparent sound. In part, the sense of greater detail and enhanced imaging may be attributed to the closer matching of tweeter pairs in each stereo system. The ribbon’s fabulously efficient wideband design reproduces the authentic tonal character of frequencies beyond 60kHz, as well as the inherent nature of the mid-band vocal region to which the ear is most sensitive.
Further tuned by FEA tools, the Gold series bass units utilize an evolved version of the dimpled RST cone surface introduced on the Gold GR and GS ranges. It takes the form of a continuous radiating dish devoid of the central voice- coil aperture. Instead, a longer voice coil and larger motor sit behind the cone in a more efficient drive assembly, which offers greater drive force, longer excursions and lower distortion, producing cleaner, more extended and accurate bass definition. Back-to-back listening tests have demonstrated that across all four stereo models, Gold sounds more open and dynamic, with a soundstage that is both taller and wider than its predecessor.
Single bolt-through driver fixings have the dual effect of improving cabinet rigidity while further reducing vibration at the driver/cabinet interface. By this innovative method, drivers are mounted on a single tensioned through-bolt, which is secured to the back of the cabinet. The bolt not only acts as a rigid cabinet brace to reduce box coloration, it removes the need for conventional driver fixing as well, effectively decoupling the driver and front baffle to eliminate a further source of unwanted resonance.
Each enclosure is rigid and curved in nature. The cabinet is further aided by radial bracing and bolt-through driver fixings, which eliminate unwanted vibrations and internal standing waves. New Gold’s HiVe II reflex port is shaped to have the same effect on air flow as a gun barrel on a bullet. Rifled grooves inside the port help to accelerate the flow and reduce turbulence, so air moves in and out of the port more efficiently for a faster more dynamic bass response.
For added stability the die-cast alloy base plinths of the floorstanding models and the dedicated ‘Gold’ speaker stand provide a solid foundation for superior acoustics, enhanced by hand-milled spikes. Non-slip rubber pads are supplied to protect wood floors.
Gold’s magnetically-fixed ‘floating’ cloth grill replaces the full-length metal grill of its Gold GX predecessor. On floor standing models, more of the cabinet’s luxurious grain-matched depth of finish is exposed and the design offers a classier, more discreet look, enhanced by a brushed aluminum badge.
Comprising high quality polypropylene lm capacitors, air core and laminated steel core inductors, individual driver crossovers are mounted on a dedicated panel accessible from the underside of each speaker. The adjacent speaker terminals are gold plated to maintain signal integrity and contact reliability. All Gold speakers are wired internally with Pure ow® Silver cable.
