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
