Break the tradition electroacoustical design principle of Hi-Vi D8.8! The Euro-American nation develops in the loudspeaker up has been be placed in a leading position. 10 years ago, Hi-Vi engineers hope to look for a break, which will make Chinese people also can design a new generation loudspeaker with high index and performance by ourselves. At that time our springboard is to design a small caliber loudspeaker, using a small box can produce a very grand low-midrange sound field. Its voice should be neutral and nobler, it also should be a modern art article. Now this D series loudspeaker basically achieve our original conceive, the D series loudspeaker adopted the latest design in a series of world new concept. 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; Progressive spider with decompressed rear volume. D8.8 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. D8.8 is excellent as a woofer for high power "no compromise" audiophile systems. It also may be used as a subwoofer in various configurations.

The design of the F10 has been optimized for balanced and dynamic low bass reproduction in compact or medium vented systems and subwoofers. The F10 utilizes a newly developed matrix of Kevlar and paper fibers. As a result, the cone weighs less, is more rigid, and has an improved dampening factor over conventional Kevlar¨ materials. The back of the cone is hand coated with a special dampening compound to further maximize performance stability and control of structural resonances. This allows distortion to be kept very low through a wide frequency and power range. The massive aluminum die-cast basket with multiple point mounting has been developed to minimize parasitic structural resonance. The driver has a vented pole piece to avoid air compression and ensure maximum power handling. Together with the long-throw design, this feature provides clean and articulated bass performance at high volume levels. The massive aluminum die-cast basket has been developed to minimize parasitic structural resonances.

Surround with low mechanical memory -CNC machined magnet structure parts for maximum precision -High power handling 3 inch voice coil with black anodized aluminum former -Vented pole piece -High density aluminum die-cast frame with multiple point mounting -Symmetric Motor Drive (SMD) technology The design of the W10 driver is based upon the benefits of an extended pole piece in a magnet system. But here we went further. Using Finite Element Analysis simulation, we optimized the complete magnet structure and specifically shaped the pole piece to achieve symmetric flux distribution along the travel path of the voice coil. This design approach provides better driving force linearity. It considerably reduces voice coil inductance modulation and DC offset of the moving system at high power levels. The result is much less distortion and more effective voice coil cooling. The cone is a paper composite reinforced with Kevlar fibers to insure proper dynamic stability and stiffness. The surround is Santoprene?, which has a low mechanical memory, providing for more accurate transient response. The large voice coil, high Xmax, and vented pole piece allow for clear and resolving performance without mechanical or thermal compression even at the highest output levels. The W10 has been optimized to achieve clean, dynamic low bass reproduction at high power levels in compact or medium size vented cabinets. The massive aluminum die-cast frame with multiple point mounting has been developed to minimize parasitic structural resonance. Recommended maximum crossover frequency is 400-1000 Hz.
