Equipped with the Flax cone, the woofers from the PS 165 FSE kit deliver a very dynamic, natural sound without colouration. The TMD (Tuned Mass Damper) surround they incorporate stabilises the surround to achieve better control, and even greater neutrality and linearity. Thanks to their built-in neodymium motor, their depth is reduced (slim, shallow basket profile): this more compact design makes them even easier to install in factory locations.
