The Martin Audio W8L Longbow is an evolution of the successful
W8L line array system. It brings a new level of performance to
the most demanding sound reinforcement applications such as
outdoor festivals, sports stadiums and the largest arenas.
Since the launch of the W8L, Martin Audio has developed a
patent pending technology, which provides an exceptional
degree of control over the curvature of the high frequency
vertical wavefront. By coupling this technology with significant
advances in high frequency device design we have created a
quad-driver, high frequency system with an impressive 10dB
greater output capability.
