The n-line array speaker employs a high-performance 12" neodymium woofer and 4 PCs of 1.7H neodymium compression drivers. The driver perfectly matches the specialized horn. And its coaxial design generates constant 120° dispersion and guarantees no interference in the cross area of horizontal coverage. By using multiple 1.7 "compression drivers, the high-frequency distortion of a single driver is significantly reduced but in the meanwhile extended longer thrown distance. The n speaker can be mounted or flown by a frame as a line array.

π-b is a compact but strong subwoofer with 2 PCs of high-performance 12" neodymium LF drivers. As the result of our decades of high power output loudspeaker development, the subwoofer enables extra high continuous rated power output by a brand new design. Improved cooling enhances the subwoofer's reliability as well as durability. The cabinet is built with high-quality multi-layer plywood. It is coated with durable polyurethane topcoat making it possible for anti-scratch, anti-impact and wind or rain resistance. Two cosy handles are equipped on both sides of the cabinet for easy transportation and stacking up. An integrated three-point lifting rigging system is equipped at each cabinet, which can be set accurately from 0°to 5°.
