Product details

HiVi D10.8 | 10"| Poly Cone Woofer

The HiVi D10.8 represents a design in which the voice coil is positioned over an undercut central pole piece with a large thermally stabilized neodymium magnet at the bottom and a 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 that substantially decreases inductance and back electromotive force modulations. The magnet structure is optimized using Finite Element Analysis technique, resulting in a radical improvement of driver linearity. The cone has a shallow, high integrity structure that is extremely rigid and dynamically stable. The large voice coil diameter allows for a more uniform cone movement, delivering clear and accurate reproduction. The vented motor design and high temperature rated voice coil provide a dramatic increase in power handling. D10.8 is an excellent woofer for high power "no compromise" audiophile systems and control monitors. It also may be used as a subwoofer in various configurations.
