Hi-Vi fully Symmetric and low distortion Motor Drive technology with long-throw linear excursion design.
The D5G is a design wherein the voice coil is positioned over a large thermally stabilized Neodymium magnet and undercut central pole piece. A specially shaped, CNC machined steel cup completes the magnetic structure from the outside, creating a shielded magnet system with symmetrical flux density distribution along the gap. The long-throw voice coil experiences a symmetric driving force and a substantial decrease of inductance and back electromotive force modulations. The whole magnet structure is optimized using Finite Element Analysis. The result of this approach is a radical improvement in driver linearity.
The cone is fabricated from a newly developed matrix of Kevlar? And paper fibers. It has a shallow, high integrity structure, which is extremely rigid and dynamically stable. The large voice coil diameter allows more uniform cone excitation, thus improving phase and transient characteristics of the driver, resulting in clear and accurate reproduction. The cone is a beautiful light gold color.
The vented design, effective heat transfer to the die-cast frame, and a high temperature rated voice coil provide a dramatic increase in power handling.
