S800N WR is a waterproof compact 3-way full range passiveplasticspeaker comprising double 8"transducers.Theadoption of coaxial driver allows very compact cabinetdesign.The system comprises one 8"Mid-low section andone 8"one-piece coaxial neodymium full range transducer.The coaxial transducer newly developed by our factory usedin S800N WR has only one magnetic circuit structure sharedby the mid-low and high section,which has effectivelysolved the phase error problem of the mid-low and highrange along X,Y and Z axis in 3D space.The diaphragmcoated with unique material reduces the distortion normally caused by thenonuniform vibration of different parts of the speaker.The adoption of sandwichtype voice coil,linear symmetrical magnetic circuit and aluminum short-circuitring has decreased THD efficiently.The standard type of S800N cabinet hasintegrated flying points for suspension application.
