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.

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.
Of Focal's 200 employees, only 15 are "allowed" to build the Utopia line of loudspeakers. "Utopia, to Jacques Mahul's way of thinking, represents the finest expression of Focal—so only the most experienced employees can build Utopia products. They are also the most critical employees and we do not push them to produce mass numbers—we push them to produce perfect products," said Gérard Chrétien, Focal's managing director (and former editor of L'Audiophile>.
