The speaker drivers from the PS 165 F3E kit combine the best of Flax technology with the latest Focal innovations to deliver one of the most natural sounds. The TMD surround (Tuned Mass Damper) is incorporated in the woofers and midranges to stabilize the surround and achieve better control neutrality and linearity: the bass is even denser the performance in the top midrange is improved and harmonic distortion reduced. Combined these speaker drivers create a precise powerful sound without coloration.
