产品介绍
The Martin Audio Wavefront W8LD is a line array downfill enclosure which connects directly to the bottom of a W8L Longbow array and covers from the front row out to up to 20m when using two W8LD cabinets. The exceptionally wide 120° horizontal dispersion increases coverage to front row central and off-stage areas, with full pattern control maintained right up to 15kHz. The all-horn design follows the same format as the W8L Longbow and continues the extension of the line array at low, mid and high frequencies.
