The Yi8 loudspeaker is a compact, passive line array module developed for high-performance fixed installations where clarity, coverage, and consistency are essential. As the installation-specific version of the Y8 loudspeaker, the Yi8 loudspeaker maintains identical acoustic performance while offering modified cabinet construction, integrated rigging hardware, and finish options suitable for permanent deployment. Featuring a 2-way design, the Yi8 loudspeaker incorporates two 8-inch neodymium drivers arranged in a dipole configuration, along with a centrally mounted 1.4-inch compression driver equipped with a wave transformer. This setup ensures consistent directivity and full-range performance across a range of demanding acoustic environments. The Yi8 loudspeaker is particularly suited to venues such as concert halls, auditoriums, houses of worship, and performance spaces, where intelligibility, defined coverage, and scalability are required. Its advanced waveguide and port design support a smooth frequency response with extended low-frequency output, while the mechanical design allows vertical arrays of up to twenty-four modules. The Yi8 loudspeaker delivers 80-degree horizontal dispersion controlled down to 500 hertz, ensuring uniform audience coverage. Available in Weather Resistant and Special Colour variants, the Yi8 loudspeaker meets both technical and environmental demands in varied installation contexts, including outdoor and architecturally sensitive spaces.
