Focal combines high-tech work stations with a phenomenal amount of hand labor. Metal drivers and inexpensive dome tweeters are heavily automated, but many drivers are assembled by hand, especially Focal's "W" composite cones.
One of Focal's core technologies is its use of "multi-ferrites," Mahul having realized that it was more precise to use multiple magnets in big drivers than it was to rely upon finding enough truly huge, uniform magnets.
Fewer loudspeaker companies have anechoic chambers than you realize. They take up an awful lot of space, for one thing. Focal has one, and it has a twist—rather than have a suspended floor, the company puts its speakers on a hydraulic jack and suspends it 30' above the floor. This makes getting massive speakers into and out of the chamber a lot easier and safer.
It seems as though there's a QC employee for every assembly employee at Guy.HF. Not exactly, Jean-Paul Guy explained. Every G.HF employee is responsible for the work that comes to him or her—so after each employee signs off on a product as good to go, the next, um, guy inspects it before accepting it. "Mistakes get made," M. Guy told me, "but we try not to perpetuate them."
Back in April, Daniel Jacques of Audio Plus, Focal's North American distributor, invited me to visit Focal's factory in St. Etienne. Since I'd never reviewed any Focal loudspeakers, I didn't know a lot about the company, but I have spent many happy hours in Jonathan Scull's ribbon chair, listening to his Grand Utopias, so I was eager to go—and to learn more.
Another hand process is stretching and fitting various layers of adhesive-impregnated glass-fiber material to the front and back of the foam center. Again, depending on the driver's purpose, different amounts of glass fiber layers are employed. Since Focal controls the flare, drive system, and crossover, the company has massive amounts of control over elements like mass and Q.
