Vivid Audio GIYA G1 S2 Speakers
Our definition of GIYA – a myriad of technical details skilfully combined to achieve a remarkable sense of sonic transparency and tonal naturalness together with a uniqueness of design forming its final appearance.
The GIYA G1 is Vivid Audio's top of the range, flagship speaker. Pioneered by Laurence Dickie, the GIYA G1 is a speaker whose deep technology aims at reproducing what's fed to it with absolute fidelity and pristine sound quality. The entire design is enspired by its function and purpose. Experts agree that this is one of the best speakers they've ever heard (Wes Phillips, Stereophile).
The shape of the GIYA is defined by proven acoustic principles unhindered by the conventional loudspeaker enclosure norms of building trapezoids out of MDF. The enclosure of the G1 represents the state-of-the-art in enclosure design and materials science. There are no off the shelf drivers here either. Every driver was carefully designed using finite element analysis.
The swirling, cochlear shape and materials of the GIYA G1's vacuum-infused, composite fibre cabinet are not so much a matter of style as of function. The woofer chamber is curved to prevent standing waves, and to save space. The teardrop shape of the GIYA's front baffle reduces cabinet reflections, and the enclosure's downward taper (noticeable when viewed from the side) allows the tapered tubes of the mid-bass, midrange and tweeter to be solidly anchored to the rear of the enclosure with a single locking screw and O-ring.
The GIYA G1 is a four way design with five drivers. Two side-firing 11" bass drivers, a 4.5" mid-bass driver, a 3" caternary dome midrange, and a 1" caternary dome high frequency driver. All diaphragms are made of anodised aluminium alloy which represents the best combination of stiffness and density when compared to titanium and magnesium, and an optimum price/ performance factor when compared to more exotic elements. These are not your typical metal drivers however. Their unique motor structure, shape and implementation utilize all of the advantages of their low mass and high stiffness, while eliminating the ringing and resonances associated with these materials.
Two 11" anodized aluminium bass drivers are mounted near the bottom of the enclosure on opposite sides of the cabinet and directly coupled to one another. The vents behind each woofer are tuned to 23 Hz. By coupling the drivers to one another instead of the enclosure, and by having the woofers move in opposing directions, you reduce mechanical vibrations being transmitted to and through the enclosure in two ways. First the drivers are physically not coupled to the enclosure directly. All vibrations move through the O-rings before encountering the enclosure. This alone reduces mechanical transmission of unwanted vibration. Second, the bass drivers themselves are moving opposite one another, when one is pushing outward, the other is moving inward at exactly the same speed and distance. This movement is actually cancelling each driver's mechanical vibrations, and greatly reducing distortion. I know of no other speaker company implementing this type of technology.
All of the vivid Audio loudspeaker drivers utilize the cylindrical, super flux ring magnet structure. This structure is literally a ring of neodymium magnets, which leaves a larger diameter hole in the centre behind the drivers. This larger hole allows for better air flow, which results in better dynamic capability and cooling of the driver's voice coil. This larger airway at the rear of the driver takes full advantage of Vivid's Tapered Tube loaded dome drivers, as these rely on having the largest hole possible in the central pole to allow the sound to radiate freely into the absorber. It also has the advantage of a more efficient aligning of the magnetic poles than the standard round magnets used on most drivers.
Located on the front baffle are the 1" catenary dome tweeter, and the 3" catenary dome midrange. The caternary shape is more parabolic than a hemispherical dome. This was found to move break up modes out of the audible range by 50% over standard hemispherical domes. The end result is a driver that plays louder and sounds very un-metallic, resulting in a loudspeaker that you can listen to for hours on end without fatigue.
In the G1 and GIYA G2, all front firing drivers, including the mid-bass unit, are coupled to long exponentially tapered tubes that are filled with an acoustically absorbant material of varying density. This smooths the driver's forward radiating frequency response greatly in addition to eliminating resonances and reflections that occur behind the driver. This accounts for the Vivid's incredible dynamics and lack of compression, especially at high listening levels.
Laurence Dickie pioneered the application of tapered tube absorbers as a means to eliminate destructive resonances and reflections from within driver enclosures. All four of the driver subsystems, including the low frequency section, have benefited from the application of this technique. So we have a tapered bass enclosure coiling around to give the visually striking effect.
Every Vivid Audio loudspeaker cabinet is hand finished using an elaborate process to ensure the very best aesthetics and finish quality.
Vivid loudspeakers come in two standard colours: pearl white and piano black. But our range of possible colours is actually limited only by your imagination. In keeping with such an individual and unique speaker, we also offer a special service that can match any colour you specify...
