Hi-Vi SD1.1- A is a new style, which be subjected to the good opinion deeply. It is one of the series units of Hi-Vi home theater. Hand treated fabric dome with rotational symmetry moving behavior; ferro fluid cooled 25mm voice coil; design with meticulous care from the American Hi-Vi engineer. Flexible lead out wires; Shielded double magnet system; Replaceable self-centering voice coil/dome assembly. The fabric with special weave provides better axial symmetry of the entire moving system which results in distortion reduction. The tweeter has very smooth frequency response evenly increasing from 2Khz. This specific feature allows to create balanced acoustic power response in a real listening environment, thus achieving better clarity and transparency of sound.

HI-Vi bloc released formally the Hi-Vi Diva series sound box in American Chicago'Hi-Vi 99 exhibition of stereo sets,1995. Introducing Swans TN28-4 loudspeaker Divas which achieved the "Exception Value Award" on CES Las Vegas 2000! In 2000, Hi-Vi Diva sound box acquired the order form of over million dollar from American agents at a blow. Total to say, Diva 2.1 can be said to be a rightness of to place easily, beautiful appearance, manufacture hard, successful Chinese loudspeaker. -"Minimum diffraction" versatile-mounting design; -Hand treated fabric dome with rotational symmetry moving behavior; -Ferro fluid cooled 28mm voice coil; -Flexible lead out wires; -Shielded, vented double magnet system with two Neodymium rings; -Large non-resonant rear acoustic chamber; -Solid metal case from anodized aluminum. The absence of a mounting flange on the TN28 allows flexible placement and diverse cabinet design. The TN28 can be placed on top of a cabinet to reduce diffraction effects and align acoustical centers of transducers. It also can be mounted in a hole anywhere on the front baffle in maximum possible vicinity to a bass-midrange driver. The solid aluminum case enclosing the magnet system provides effective cooling. The special weave of the fabric results in better axial symmetry of the entire moving system. The tweeter has very smooth on-axis and off-axis frequency response delivering excellent acoustic power dispersion. The TN28 creates an accurate imaging source and is distinguished by exceptionally transparent and balanced sound. TN28- Hi-Vi electroacoustic technology of crystallize of the decade

The high sound is a soul of system, its tamber, transient, texture, dynamic state compress, distortion etc. These factors usually all rise the decisive function. According to the above factors, Hi-Vi company has ever created a referenced unit- Q1. Believing its mellow tamber, outstanding texture and incomparable transient, which leave the indelible memory in many persons' brain. Science and technology at progress unremittingly, more and more high expectation urge us to improve each function of this classic loudspeaker continuously, so Q1R appeared in 2003. Dome (28mm) membrance material with improved material rate and damping in the surface. Ferro fluid cooled and CCAW coil. High performance shielding magnetic structure with finite element optimize magnet-resistant system. Its excellent antimagnetic design widens the range of use. Improved design in resonator cavity with two cavities connecting through a pipe and adaptive damping material to absorb noise. Q1r is based on Q1 for 2003 with more natural sound performance.
