Line Array Speakers

LA212 line array is a large-scale 3-way, tri-amped system, which provides frequency ranges from 50Hz to 16KHz. The system consists  of 2X75 mm(voice coil)neodymium compression drivers, one 10″ neodymium MF driver and 2X12″ neodymium LF drivers to achieve an impressive headroom.

The Low frequency adopts a couple of 12″cone LF driver. Each unit's power handling is 400W and connects in series. One 10″ MF driver with high sensitivity is mounted at the rear of the HF driver to make up an coaxial configuration. A MF phase plug is mounted on the surface of the mediant, which has excellently improved the directivity and sensitivity. The HF section ultilises 2x75mm(voice coil) neodymium complex film drivers coupled with a 90 °exponential constant horn via plane-wave transducer to make an coherent wavefront. The HF section with 113 dB sensitivity can make the loudspeaker generate 140 dB peak SPL output.

LA212 is a trapezoidal speaker with the seamless gap between each cabinet.
The adjustable angle of the cabinet is 0-7.5°, 1° per step, the rigging hardwares are made of high strength steel . It is safe enough, whilst 16 enclosures are flying , the safety factor will reach up to 7:1.

The enclosure panel is constructed by 18mm panel, and 15mm for others. It is finished with gray textured water paint. Two recessed handle cups are mounted on both sides of the enclosure for easy lifting and carrying. A rear panel connector plate carries 2 Neutrik Speakon NL4MP connectors for loop in and loop out connections to additional enclosure. On the other hand, the enclosure is well protected by the gray mesh grill with the transaudient reticulated foam.
