A loudspeaker as a whole works optimally when its individual components harmonise well together and can concentrate completely on their own actual job. To ensure that the woofer and subwoofer can deliver a perfect result in this loudspeaker, we have equipped them with FE Driver Dynamics technology. An optimised ferrite drive system, non-magnetic baskets with voice coil ventilation and large basket perforations minimise electrical and mechanical losses. In this way, the entire drive energy flows into signal reproduction, ensuring maximum precision there.
