The P.Audio 3LINE-C is a high performance two-way vertical column array system with a multitude of rigging possibilities for fixed installation and portable use. The 3LINE-C enclosure is made from folded steel with butyl rubber damping material to prevent resonances. The cabinet is zinc plated and powder coated to prevent corrosion of the cabinet itself. The cabinet has also been designed with folds in the sidewalls to improve strength, and move resonance of the panel to a higher frequency.
The 3LINE-C uses eight three-inch woofers for low-frequency reproduction. The woofers are closely spaced to improve vertical directivity and allow the crossover point to the tweeter to placed higher up. The tweeter mounting is placed in front of the woofers to provide more consistent directivity across the crossover region. The six silk dome tweeters extend the upper-frequency limit to past 20kHz on axis. The on board passive crossover network is designed for optimal frequency response and accurate sound. The 3LINE-C also includes a 50w line matching transformer and selector switch to provide optimal ease of use when used in large installations. The tweeter section is mounted at the top of the cabinet in order to allow two cabinets to be stacked on top of one another, and still maintain pattern control at high frequencies.
The 3LINE-C is ideal for fixed installations using the optional 3L-PTB wall bracket, and the 3L-LB link bracket for stacking two enclosures on top of each other. The 3L-SPA speaker pole adaptor can be used for portable system requirements, which allows mounting to a standard 35mm speaker pole.
