HiVi D8G 8″ Mid-Bass Yellow Kevlar Cone Casting Aluminum Frame 8ohm – Pair
Overview:
The HiVi D8G speaker represents a design in which the voice coil is positioned over a large thermally stabilized neodymium magnet and undercut pole piece.
Highlights:
- Light and extremely rigid cone made from Kevlar/paper composite
- High loss rubber surround
- Shielded vented Neodymium magnet system
- Long-throw motor structure
- High linear excursion capability
- High-density aluminum die-cast frame
Product Description:
The HiVi D8G speaker represents a design in which the voice coil is positioned over a large thermally stabilized neodymium magnet and undercut 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 that substantially decreases inductance and back electromotive force modulations. The whole magnet structure is optimized using the Finite Element Analysis technique, and the result is a radical improvement of 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. A large voice coil diameter allows for much more uniform cone movement, resulting in clear and accurate reproduction. The vented motor design effectively transfers heat to the die-cast frame, and along with a high temperature Kapton former voice coil, provides a dramatic increase in power handling.
