1. LK-2236L is a 3-way line array speaker, it is specially designed for largescale sound reinforcement applications. LK-2236L can be two way full range as well (HF+MF&LF by built-in crossover, LF bi-amp ), this is easy done by a switchable crossover at rear panel.
2. LK-2236L housing 2× 12"LF woofers, one horn loaded 10" MF driver and two 1.5"exit HF Neodymium compression drivers with 3" voice coil mounted to a dedicated wave-shaping device. 12" woofers are coated by all weather-proof material which is IP43 level.
3. The mechanical and acoustical design enables flown vertical columns of up to twelve loudspeakers to be suspended using vertical splay angles between them of 0° To 6° With a 1° Resolution.
4. The symmetrical dipolar arrangement of the LF drivers around the centrally mounted coaxial MF and HF components allows a smooth overlap of the adjacent frequency bands in the crossover design and this results in an exceptional 120° Horizontal constant directivity dispersion control nominally being maintained down to 350Hz.
5. Cabinets are mechanically connected using the rigging likes on both sides of the cabinets front, and with a central rigging link at the rear of the loudspeaker. The LK-2236L cabinets is constructed of 18mm/25mm birch plywood.
6. The front of the loudspeaker cabinet is protected by a rigid metal grill. The side and rear panels incorporate six handles, and two NL8 connectors wired in parallel are also mounted at the rear.
7. LK-2218 & LK-2218B are the ideal subwoofers for LK-2236L line array speaker. The 18" woofers are using imported & reinforced paper cone, voice coil is pure cuprum round-wire and its frame is 405 degree
Fireproof material. What's more, the spider is 360° Thermal Stable material.

Viewing through China PA history, with the recession of home audio and the emersion of professional audio business opportunities, there rise a large number of manufacturers, within which, some are well qualified ones. But unfortunately, as always existing at the primary stage of every industry, there are quite a few of badly-equipped small factories looking after quick money.
DEMA products are mostly exported to European markets, some are well accepted in many Asian countries, and quickly gain the market favor from some American, Australian, African countries. High end acoustic system of DEMA, the sound reversion can reach even surpass some well-known European or American brands.
DEMA products can receive high appraisal from current customers, that's worth congratulating. But, being PA systems manufacturer, we are plenty to do. The task for future is still painstaking and there is a long road to walk. Our mission is to be an Excellent Acoustic Equipment Provide all over the world!
