HiVi D 10.8 Woofer

Shallow mineral filled polypropylene cone; Fatigue resistant foam surround; Shielded vented magnet system with huge Neodymium magnet; Long-throw symmetrically driving motor structure; Extreme power handling voice coil with 100 mm black anodized aluminum former; High density aluminum die-cast frame; Flat linear spider with decompressed rear volume. D10.8 represents a design where the voice coil is positioned over an undercut central pole piece with a large thermally stabilized Neodymium magnet at the bottom and high energy ceramic magnet on the top. 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 substantial decrease of inductance and back electromotive force modulations. The whole magnet structure is optimized using Finite Element Analysis. The result is a radical improvement of driver linearity. The cone 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 vented design, effective and uniform cooling of a high temperature rated voice coil provide a dramatic increase of power handling. D10.8 is excellent as a woofer for " no compromise" audiophile quality speaker systems and control monitors. It also can be used as a subwoofer in various configurations.$89.00/ea
