VT - 4888 series linear speaker is according to the speaker development experience for many years, our company through several strict design, experiment, test and design of high frequency spectrum correction for the world's advanced, undistorted acoustic surface load transmission technology research and development and become more professional unit three points frequency linear performance speakers, are widely used in outdoor large performance, large clubs, auditorium, theater high standard high demand of mobile, fixed environment use. VT - 4888 series speakers using three points frequency built-in frequency cell structure, smooth sound curve, reduce sound engineer field debugging problems and use external speaker processor frequency compensation of any defects.Divider using world advanced BASSBOX - OVER aided design software and acoustic test software design and become, DAAS frequency response curve is smooth, high frequency of intermediate frequency natural and clear and bright, full round, surrounded by low-frequency strong rich feeling.With multipoint hanging structure can meet the implementation of a variety of different forms of fixed installation. (1) the high unit adopts high quality titanium membrane (2 only 44 core 120 magnetic) array layout, make sound surface stereo multi-dimensional uniform coverage. (2) the unit alto unit adopts the taiwan-owned TIANSOUT company specialized design production of high-power 6.5 -inch amplification unit.(4 140 only 6.5 inch 48 core magnetic) combined with phase diffusion and horn diffusion structure ensure the spread of the intermediate frequency and coverage (3) the bass unit (2 only 12 inch 75 core 190 magnetic) combined with low-frequency maze waveguide strong technology to strengthen the power of the bass diffusion of low frequency and directivity. Its overall performance for the bass strength strong, surrounded by a sense of fullness. Alto plump, high clear delicate, audio-visual accurate, detailed, telepresence, surrounded by feeling.And has the high power stable and durable characteristics.
