L-ACOUSTICS KS21 HIGH POWER COMPACT SUBWOOFER

KS21 is a compact reference subwoofer designed to extend the bandwidth of A15 and A10 systems. KS21 features one high excursion, direct radiating 21‘‘ transducer mounted in a bass-reflex tuned enclosure.

KS21 couples with A15 and A10 to reinforce contour and extend bandwidth to 29 Hz and 31 Hz respectively. KS21 features L-Vents that substantially reduce turbulence and port noise at high levels while also increasing LF efficiency. The association of modern components and laminar vents greatly improves short-term SPL compared to similar-sized subwoofers.

The KS21 frequency response is optimized to couple perfectly with both systems. KS21 features a two-point, integrated rigging system that is compatible with A15. Combinations of KS21 and A15 can be flown or stacked to form a full range line source. KS21 also integrates a threaded insert to enable pole-mount configurations of A15 or A10.

KS21 can be deployed in standard or cardioid configurations with dedicated presets, for flown and stacked deployment.
