It is used for all kinds of rock-and roll bar, hall, club and all kinds of dynamic performance in
entertainment for sound reinforcement
It is used for high quality music repeating, and can match Beta 3 EJ218 high power subwoofer speaker
3 J series loudspeaker is mainly used for all kinds of rock-and-roll bar, entertainment bar, club, and all kinds
of dynamic performance, cellular reinforcement sound. This series includes three different types of speakers,
2 types of two-way full range speaker ,and one subwoofer speaker. .
12 inch full range and 15 inch full range speakers are pentagonal section; they are convenient to make an array.
When it is used for echo on the stage , it can debase the production of wave inside ,and we adopt selected high
strength MDF plate ,which has enough strength and it can absorb the heterogeneral sound of resonance .EJ series
adopts standard flying configuration ,and SPK speakon socket input ,so it is convenient for fixing. .
J Series products are developed and produced by combination of the latest computerized stimulation design
technology, the latest loudspeaker material and manufacturing technology. All transducers adopt the optimized
magnetic circuit having high magnetic energy, low distortion and excellent. LF uses nonlinear thickness long
fabric paper cone with special painting cloth surround and high power sandwich type voice coil. HF adopts high
temperature treatment Ti diaphragm, voice coil with copper cladding aluminum wire and compression cavity
designed with linear phase technology. The products have good sound field coverage through broad dispersion
horn and the latest adjustable delay symmetric circuit was also used for improving reliability as well as sound
quality. Voice coil with diameter 100mm and magnetic circuit with diameter 220mm were used for subwoofer to
