SOLID FOUNDATIONS L-Acoustics subwoofers complement systems in applications where extended bandwidth is required. All subs incorporate high excursion drivers, ultra-low vibration walls and laminar airflow L-Vents with a flared profile, resulting in dramatic reduction of port noise, maximized dynamics and power handling and an exceptional level of performance. L-Acoustics subwoofers can be deployed in diverse modes, making them versatile enough to address any rental or fixed installation application. Engineers and sound designers can choose from standard or cardioid configurations, creating a variety of symmetric and asymmetric directivity patterns adapted to each specific design. The Subwoofer range includes: SB15P Dedicated to the P Series SB15m Dedicated to the X Series and flyable with Kiva SB18 (i/m) Companion to the X Series, flyable with ARCS WiFo and Kara(i) K1-SB Flyable with K2 and K1 for low frequency contour or throw reinforcement SB28 Universal KS28 Reference subwoofer
