Installed Sound Products

The IS fifteen three (153) series of loudspeakers are specifically designed for providing reinforcement in fixed installations where high sonic performance and flexibility in precise pattern control are critical. Precision designed with Mathematically Modelled Dispersion ™ the fifteen three series provide exceptionally linear pattern control through crossover making the series perfect for critical applications. Active versions used in conjunction with K8 products provide a factory tuned and easily-managed reinforcement system for night clubs, auditoria, houses of worship, performance halls, arenas and stadiums.
