The Martin borther 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 brother 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.
