FOCAL/ PS 165 F3E

The sound of flax In their pursuit of sonic excellence, Focal discovered that a flax woofer cone produces a dynamic sound that's worthy of their reputation. At half the weight of fiberglass, these flax fibers help create a very rigid yet lightweight cone that ensures accuracy and limits unwanted vibrations. Tuned mass damper Focal knows that control is of the utmost importance to accurate sound. Their patented surround employs "tuned mass damper" technology used to enhance the structural stabilization of earthquake-resistant skyscrapers — seriously!! With greater control of the woofer cone, you'll gain smoother, more natural sound.
