Che questi Vivid G1 siano diffusori originali si percepisce già al primo sguardo. Che siano anche densi di progettualità lo si capisce dalle positive recensioni che autorevoli riviste internazionali hanno stilato.
Ma cosa hanno di speciale questi strumenti per la riproduzione della musica che li rende così interessanti? Certamente il prezzo: 65.000 dollari la coppia per due diffusori da pavimento deve essere giustificato da un risultato sonico eccellente oltre cha da un progetto innovativo e da materiali all’avanguardia.
Il cabinet innovativo non lo è completamente, dal momento che il polimero usato non è una novità assoluta, e un mobile così realizzato mi fa nutrire qualche perplessità sulle risonanze generate dal materiale (fibra composita rinforzato con fibra di carbonio), nonostante la particolare forma del cabinet utile ad abbatterle. Ma anche la forma cocleare, benché nelle G1 sia in versione estremamente semplificata, è già stata proposta anni fa, con successo, dalla B&W nelle sue Nautilus. Non a caso i patron di Vivid sono Robert Trunz e Laurence Dickie, tecnici della B&W. I trasduttori superiori, tutti a bassa massa ed alta rigidità (alluminio) hanno camere separate che, come nelle Nautilus, hanno una forma conica che si va a posizionare con l’estremità nella parte posteriore del cabint.
I diffusori sono 4 vie 5 altoparlanti, con tweeter e midrange alto a cupola con magnete al neodimio, midrange basso e due woofer a cono in alluminio. Le caratteristiche distintive delle G1 sono essenzialmente tre: i woofer sono alloggiati lateralmente e contrapposti fra loro; i componenti sono tutti di ottima qualità; il sistema di accordo ha una particolare struttura.
La dinamica, la trasparenza e la ricostruzione scenica sono le caratteristiche soniche maggiormente apprezzate dagli appassionati. Sulla timbrica qualche piccola riserva è mossa al materiale che costituisce i trasduttori. L’alluminio, nonostante i grandi pregi relativi alla bassa massa che conferisce velocità e di conseguenza dinamica, ha una voce riconoscibile. L’estrema pulizia sonica è fornita a fronte di un rigore timbrico che nulla concede al fascino sonico di altri trasduttori più clementi nelle prestazioni, ma dalla voce più… accomodante.
Wrapped within GIYA’s distinctive shell-like appearance lies an exceptional level of engineering detail and acoustic design sophistication. Every element of the design has been refined to an extraordinary degree to produce the flagship of the Vivid Audio speaker range.
Vivid Audio GIYA G1 loudspeaker
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)…...See more
Vivid Audio G1Giya loudspeaker
By Wes Phillips • Posted: Jul 12, 2010
Over the years that I’ve been reviewing hi-fi, I’ve had my share of loudspeakers that drew comments from everyone who visited during the audition period. Some of those comments were about the speakers’ appearance—most often about their size—and some were about how good they sounded. Vivid’s G1Giya loudspeaker ($65,000/pair), its narrow-baffled, swirling cochlear shape molded from fiber-reinforced composite, elicited more comments of both types than has any other speaker I’ve reviewed.
This started even before I got them into my living room, as Philip O’Hanlon, of Vivid importer On a Higher Note, and Stealth Audio’s Serguei Timachev, and I unpacked the Giyas from their crates on the street (while the Giyas made it safely down my front hall, the crates couldn’t). My next-door neighbor and his next-door neighbor sauntered over to see what we were doing. “Wow. Are those art or are they speakers?”
As it turned out, the G1Giya is both…..See more
Vivid Audio • G1 Giya Loudspeakers
Innovative thinking on speaker design produces a new statement in speaker sound.
by Marc Mickelson | February 9, 2010
What you will first notice about the Vivid G1 Giya speaker, even if it is pounding out the choral finale of Beethoven’s Ninth, is its shape. From the front, it resembles a bowling pin, and from the side either an elf’s cap or a dollop of frosting. It’s whimsical and elegant, just what so many of the massive speakers in its rarefied price range are not. But the Giya’s look is not for show. It’s an outward sign of some innovative engineering. The G1 Giya is a clean-sheet design — a speaker whose deep technology aims at reproducing what’s fed to it with absolute fidelity….See more
“I’ve heard some extremely expensive speakers, costing two and even three times the Vivid’s price, that can do one or two of the things the G1 Giya do so well. But I can’t think of any speaker I’ve auditioned that does everything as well as the Giyas: superb imaging, unmatched dynamic range, holographic soundstaging, and that immutable, possibly unquantifiable quality known as musicality.
Is Vivid Audio’s G1 Giya the best loudspeaker I’ve ever heard ? Yes. And it will be my yardstick from now on. Whether or not you can afford a pair, you should listen to them so that you know exactly what is possible in a high-end loudspeaker.”
Wes Phillips, July 2010 Stereophile
G1 Giya was awarded the Stereo Sound Grand Prix 2008 at the annual competition held by the “STEREO SOUND”, which is the most authoritative audio magazine in Asia. (The prize was once given to K-1).
On top of that, G1 Giya won the “GOLDEN SOUND” prize, which is given only to the best of the Grand Prix winners.
The best twenty models of the audio equipments introduced in the past year are selected as the Grand Prix winners by seven-member selection committee of expert writers and editors of the Stereo Sound.…..See more
Vivid Audio Giya G1 Speaker Review
By: Ed Momkus March 2014
A Fantasy Come True
Ohhh My God… Explosively Dynamic. Lightning Fast. Incredibly Articulate. Highly Extended. Insanely Detailed. Organically Coherent. Tonally Natural. Chameleon-like with all music. Take your pick.
A few months ago Constantine Soo gave me a call and asked: “If you had the choice of reviewing any speaker you desire, what would you choose?” What the heck do you mean by that Constantine!?! He said if I gave him a list of three speakers he’d see if he could line up a review of one of them. My brain immediately said “Whoa!”
Fast forward a few weeks later. I had reluctantly whittled down a seemingly impossible-to-reduce list to seven, called Constantine to tell him that I was seriously conflicted about which of the seven could be eliminated to take it to three finalists.
My list included several speakers I was very impressed with, including the MBL 101, Avalon Acoustics Isis, B&W Nautilus (the Nautilus), and Wilson Audio Maxx, and I thought he would help me cull the list. Instead he wanted to know why the Vivid G1 wasn’t on the list. “You’re a B&W fan, and the G1′s are designed by Lawrence Dicke, who designed the Nautilus.” I told him that the G1 was one of the high end speakers I’d never…See More
When it comes to hotbeds of high-end audio, South Africa is not the first place that comes to mind. Yet this is the home of Vivid Audio, maker of beautifully curvaceous speakers, including the flagship Giya, which is available in two versions—the original G1 and the new, smaller G2 introduced at CES 2010.
Designed by Laurence Dickie, who also created the B&W Nautilus, the Giya is based on the concept of tapered-tube loading. Each driver is mounted at the mouth of an exponentially tapered tube with damping material at the far end to absorb the backwave. But unlike the Nautilus, the smaller tubes are hidden within the gracefully curved, carbon-fiber cabinet, which forms the ported tube for the woofers.
Speaking of drivers, the Giya’s are all made by Vivid—they are not outsourced as with so many other speakers. And all diaphragms are made of the same material, a magnesium/aluminum composite that is said to achieve a very high degree of coherence and linearity. The 1-inch dome tweeter, 2-inch dome midrange, and 6.5-inch cone mid-bass driver are positioned relatively close to each other with no sharp corners anywhere to diffract the sound…..See more
GIYA is a loudspeaker system like no other. A myriad of technical details skilfully combined to achieve a remarkable sense of pistonic transparency and tonal naturalness together with a uniqueness of design forming its final appearance.
Their very shape is defined by proven acoustic principles taken to their logical conclusions, untethered by conventional wisdom and common construction techniques. Every element of the design has been refined to an extraordinary degree – from our patented hand-built drive units, to our advanced vacuum infused composite enclosure, to our relentless elimination of resonances and reflections.
