L-Acoustics KS21 Subwoofer

L-Acoustics KS21 is the ideal companion for small to large events that require bandwidth extension and strong impact in a compact enclosure. KS21 is a compact reference subwoofer designed with one high excursion, direct radiating 21" transducer mounted in a bass-reflex tuned enclosure. It features L-Vents that substantially reduce turbulence and port noise at high levels while also increasing LF efficiency. KS21 features a two-point, integrated rigging system and can be deployed in standard or cardioid configurations with dedicated presets, for flown and stacked deployment. The KS21 enclosure is constructed of premium grade Baltic beech and birch plywood to ensure maximum acoustical and mechanical integrity. Bent wood technology combined with a thickness optimization process maximizes internal volume while attaining the low weight of 49 kg. KS21 integrates a patent pending two-point, captive rigging system that simplifies deployment and provides visual safety assessment.
