Just by chance, four Giya G3 flanked by 2 Giya G2 and of course, the original and flagship Giya G1, all finished in Piano!

4對Giya G3與兩對Giya G2當然還有旗艦級Giya G1, 黑色鋼烤版本。

This takes the first break up frequency to above 44kHz for D26, and to above 20kHz for D50...

And here, G3 filter networks are being populated and hard wired point-to-point. We have recently upgraded the quality of our boards by utilising our CNC mill to cut the boards for us, neater and quicker.

G3的濾波網路，最近升級使用CNC mill來裁切電路板，更乾淨也更快唷!

This is a picture of the very first production G1 Giyas, shipped in 2008 to Audio Gallery in Korea. Pretty wild colour!

More scenes from the factory: Here we have one of our mixing banks populated with every colour toner you can imagine, each in solid, metallic and pearlescent variants. Our computerised mixing station has literally tens of thousands of colour mix recipes - at the moment we are painting a C1 in Bugatti Sprint Blue for Stella Inc in Japan.

更多的工廠場景之一:這些都是顏色基料，利用電腦精準的混合達到所需的效果-此時正在準備為Bugatti Sprint Blue的C1做準備。

And another view of the amazing showroom at AC2 in Japan, with Dic in attendance.

I was recently sent this moody image from the Alkmaar Hi Fi show earlier this year.

And a great image of the line that defines the transition from convex to concave on GIYA G2

Searching for the Extreme: Laurence Dickie of Vivid Audio -- Part Two

In Part One of this feature interview with Laurence Dickie, loudspeaker designer for Vivid Audio, we explored his foundational experiences and the gestation of his philosophy of sound reproduction by high-performance audio products. In Part Two we turn to Vivid Audio specifically, and to Dickie’s challenges and achievements in the past decade. Philip Guttentag (cofounder of Vivid Audio) and Philip O’Hanlon (US distributor), also present, each occasionally joined in.
Peter Roth: Let’s turn to the present, and Vivid Audio’s Giya line of loudspeakers. I’m interested in the differences between the C125 bass driver used in the Oval series and the C125S midbass driver used in the Giyas.
Laurence Dickie: They are distinct, different drivers. Giya-series loudspeakers are true four-ways. That means that the C125S, which some would call a 6.5" driver, has to operate only from 220 to 880Hz. Accordingly, the excursion requirements are far smaller than for the standard C125, which functions deep into the bass with a diaphragm travel of +/-10mm. In the C125S application, only a couple of millimeters of driver travel are needed to give us 120dB at crossover. This means we can concentrate the magnetic flux into a smaller zone -- a smaller gap length -- and so we’ve also taken the opportunity to reduce the gap clearances. With tighter tolerances, the driver assembly is little bit fussier, and of course is more susceptible to contamination, but that is just a little reality of manufacturing -- which is fine, and in fact we have had no difficulty with it. We gain 3dB efficiency in the main passband. You wouldn’t be able to use the S driver in a full-range system because it wouldn’t plumb the depths. The excursion limit, the X-max (the length of the magnetic gap), is too small for a reasonable amount of sound output in the bass.
PR: When Doug Schneider measured the review pair of Giya G2s at Canada’s National Research Council, it was only the second speaker they’d measured to test with 0% distortion throughout the 200Hz-1kHz band, which is such an important range.
LD: Yeah, that was nice to see, actually. It was right off the top of the scale.

Vivid Audio Germany recently installed this pair of Piano K1's. Interesting rack! Thank you for the photograph!

We're flat out at Vivid Audio at the moment, both with production and a host of R&D projects for Laurence Dickie and his team. In the meantime, here is one of our technicians, Nondu, constructing a carbon fibre sandwich panel base for a GIYA G2. This process requires skill and patience as we do not use prepreg carbon fibre fabric. All the core material is CNC machined on site.

她叫Nondu，是負責組裝碳纖維夾心板的技術人員，所在位置為GIYA G2的組裝基地。
