The line array series contains various models consisting of active and passive models for horizontal and vertical deployment complemented by reliable flying equipment. Selected models are also available in the weatherproof version, making them ideally suited for any outdoor application requiring a line array system with state-of-the-art sound performance and optimal scalability.

PL312F - Dual 12" Two way Weatherproof Line Array Speaker


Dual 12" Two way Weatherproof Line Array Speaker


The PL waterproof line array system is composed of the PL312F dual 12" full-frequency waterproof speaker and thePL218BF dual 18" subwoofer. PL312F speakers can be gro-uped into 8 or 16 units in a flying line array when needed, and the PL218BF can be grouped into 4 or 8 units to form a bass sound field. The line array system Is compact and lightweight with simple installation and connection, it is specially designed for outdoor touring performances.

PL waterproof line array speaker is designed based on the IP54 international waterproof rating standard, primarily used for outdoor mobile performance that meets the prof- essional sound reinforcement needs of unexpected rainfall weather and humid environment with high moisture density. 

All components of PL312F are designed following the IP54 international waterproof rating standard, and the cabinetstructure is specifically designed with diversion and anti- splashing installation. The equipment is assembled with a unique production sealing process to ensure the equipment reaches the waterproof safety features of the IP54 rating. It also utilizes the function characteristic of executing high- quality sound reproduction. 

The fan-shaped cylindrical wave emitted by each speaker in the PL waterproof line array speakers can be seamlessly coupled to form a coherent cylindrical wave. The opening angle between the two speakers is adjustable from 0 t ° o 10° .

 The LF transducer optimizes the magnetic circuit thr-ough finite element analysis to achieve ultra-low distortion and maximum clarity under high sound pressure. It has the overheating protection function of the driver temperature, and the flawless protection circuit is entirely safe and reliable.

PL312F adopts a multifunctional structural design, and the cabinet is composed of imported plywood from Russia. The surface utilizes polyurethane spray treatment to pro- vide superior weather resistance. The cabinet is equipped with a specified flying frame that can be conveniently and reliably installed and hung according to different environ- ments.
