Overview
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.
