The Martin Audio W8LMD is a mini, wide-dispersion vertically arrayable enclosure. It can be used individually and in small quantities for short to medium throw applications (up to 30 metres) as well as a downfill element for the W8LM. Its 20 degree 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.
