The Martin Audio W8LCDI is a compact, wide dispersion,  
vertically arrayable enclosure designed for the fixed installation  
market. It can be used individually and in small quantities for short  
to medium throw (up to 40 metres) applications as well as a  
downfill element for the W8LCI. Its 20º vertical dispersion requires  
fewer cabinets to cover the same area as a conventional line array  
element, yet it still benefits from the smooth, predictable coverage  
of a vertically coupled system.
