The L-Acoustics KS28 is a high-performance reference subwoofer designed to extend system bandwidth with authority and precision. Its dual 18-inch high-excursion neodymium drivers operate in a bass-reflex enclosure with L-Vents to minimise turbulence and port noise, delivering clean, impactful low end down to 25 Hz. Engineered from birch and beech plywood with comprehensive internal bracing, the cabinet offers maximum acoustic volume at a practical 79 kg, aided by six ergonomic handles, side runners and floor glides for secure stacking and easy handling.
Seamless integration with the LA12X amplified controller unlocks advanced presets, filtering and L-Drive protection, with standard and cardioid configurations for controlled directivity in ground-stacked or flown deployments. A two-point rigging system supports horizontal or vertical orientation, while robust SpeakON connectivity and 4-ohm impedance simplify system design. A steel grille with corrosion protection and acoustically transparent fabric ensures durability for touring and fixed installations alike.
Ideal for stadiums, arenas, festivals and large-scale tours, the KS28 supplies powerful, controlled low-frequency reinforcement for line array and point-source systems where headroom, punch and consistency are critical.
