Vivid Giya G4

The day after these little Giyas arrived designer Lawrence ‘Dic’ Dickie was off to Durban in South Africa to set up a test and measurement facility in Vivid’s new factory. But the company was not due to move to said factory unitl the day after he arrived and he had two weeks in which to create the perfect environment for R&D and make serious progress with a new model. And I thought my life was hectic!

The G4 was created in response to demand from Japanese audiophiles for a smaller Giya, but that was the story with both the G2 and G3, it seems that small(er) is indeed beautiful when it comes to curvy speakers. The G4 is not that much smaller than the G3; it is just 101cm in height, although you can buy a set of wild teak blocks from Vivid that bring the G4s’ height up by 100mm, which puts the tweeters at ear level, but means the speaker is no longer quite so diminutive. 

Pictures do the Vivid some justice, but don’t express its scale well. The Giya G1 seems to have lodged into the audiophile psyche and people mistakenly think ‘smaller’ means ‘a little smaller’ because the shape of the G1, G2, G3, and now G4 are similar. In the flesh, however, the block-free G4 really is small; coming up to hip height or so on most people. This has a slight ‘Ames room’ because the G4 looks like it should be 2m tall and yet is half that height in reality.

Apparently the G3 is the most popular model in the Giya range, so maybe Vivid has gone small enough with the G4. But still the question of whether there will be a G5 had to be asked. Dic, “cannot think of any reason to go smaller” and has, “no intention of making a four-way G5”. However, a three-way “should not be ruled out” in future.

A more significant difference between the G3 and G4 is that the G4 has a slimmer baffle, a change that meant that the 125mm lower midrange driver used on the G3 could not be employed, so Dic designed a new driver for this application with a 100mm cone called the C100S. Like its predecessor, the C100S has an aluminium alloy cone with a computer FEA optimised profile that pushes the first break up mode up to a point where it’s safely out-of-band. As in the case of the bass drivers, the crossover slope ensures that this is well below audibility. The bass drivers on the G4 are the same size as those on the Vivid B1 Decade reviewed in issue 137, and they have the same cone, but that’s where the similarity ends. In the G4 there are two side-firing bass drivers placed back-to-back so that they oppose one another’s actions in the widest part of the cabinet; these are C125L drivers, where the suffix stands for long throw. The voice coils are copper rather than copper plated aluminium so that they are heavier and have greater heat dissipating capabilities, which means they can be driven harder and thus go louder for longer. The G4 may look like a ballerina, but just like such dancers it is actually as hard as nails, and plays nearly as loud as the nine inch variety.
