◆ Over the years, Yun Qiang has been committed to the development and research of high qual ity voice column loudspeaker system.
Our goal is to transform the advantage of the modular sound column system into a compact system form, which has become easy
to achieve with the successful development of our CV series of speaker systems. In order to achieve these goals, a new system
form is needed. The key is to ampl ify and replay the original sound source at a higher level. This new concept and system form is
developed in combination with al l the advantages of the modular sound column system. The shape of the sound box is the result
of a logical and l inear source. The most special design is that the vertical 20 degree wavefront is also designed to be an asymmetrical
energy diffusion beam with a downward 7 degrees to achieve the proper axis directivity of the entire cyl indrical speaker system
when it is instal led vertical ly. From a mechanical point of view, size and weight have been minimized through the proper use of shel l
materials and magnet systems and other components.
