The L-Acoustics KS28 is a reference high-power subwoofer engineered to deliver exceptional low-frequency performance for the world's most demanding touring, festival and installation applications. Combining immense output with remarkable clarity and control, the KS28 has become a preferred choice for production companies and system designers seeking uncompromising bass performance.
Featuring dual high-excursion 18-inch neodymium drivers housed within a sophisticated bass-reflex enclosure, the KS28 delivers powerful and accurate low-frequency reproduction down to 25 Hz. Advanced L-Vents technology minimises turbulence and distortion, ensuring clean, impactful bass even at extreme sound pressure levels.
Capable of producing up to 143 dB SPL, the KS28 provides the foundation for large-scale line array systems including K1, K2, K3 and Kara II deployments. Its versatile design allows both standard and cardioid configurations, giving system engineers greater control over low-frequency coverage while reducing unwanted energy on stage and in surrounding areas.
Designed for both flown and ground-stacked applications, the KS28 combines impressive output with practical deployment features, making it equally at home on international tours, major festivals, arenas, theatres and premium fixed installations.
