Then the Miracle Fabric
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.
When the proper number of layers have been "relaxed" and built up, the drivers are placed within gently heated molds and finished. Then they are precision-trimmed with a water jet cutter.
