The LD180CR04 from ATOHM is a woofer loudspeaker designed for the realization of 2-channel system of very high quality.
This HP is equipped with a specific alloy membrane combined with a LDSO (Low Diffraction Surrounding) peripheral suspension. The latter is characterized by a particular profile ensuring a progressive fractionation of the suspension at the medium frequencies.
Its moFWI (Force Without Inductance) technology. The geometry of the component parts has been optimized to obtain a large and symmetrical force factor. The core has a copper ring that limits the creation of currents induced in the polar parts. This technology allows the reduction and linearization of the inductance value of the winding. The result is a reduction in distortion by odd harmonics and intermodulation as well as a more linear and extended bandwidth.
This superb HP canbe characterized by this: excellent efficiency, very low distortion rates, and high excursion capacities.
