The P.Audio 3Line-C is a high-performance two-way vertical column array speaker with a multitude of available rigging accessories for flexibility for installation and portable applications. The 3Line-C has 14 drivers - 8 x 3-inch closed-spaced woofers for low-frequency reproduction and 6 x 1-inch silk dome tweeters positioned at the top of the enclosure for good coverage. This component configuration provides wide response, good dispersion while still maintaining a slim, elegant appearance.This design also allows multiple 3Line-C systems to be stacked vertically while still maintaining good pattern control at high frequencies. The 3Line-C's enclosure is made of folded steel with butyl rubber damping that minimizes resonances. The enclosure is only 92 mm / 3.6 inches wide, thereby making it less visually conspicuous than typical "box" speakers. The 3Line-C's combination of wide horizontal dispersion, well-controlled vertical coverage, high sensitivity and high power handling provides highly intelligible sound with big output that enable its use even in reverberant spaces.
