  • Page 7: Introduction

    A15 deployment requires a single preset that is optimized to provide amazing plug-and-play performance for both A15 models regardless of L-Fins conguration. Performance can be further enhanced with L-Acoustics software optimization tools. A15 provides the low frequency contour of a large concert system and the dedicated KS21 subwoofer can be ground- stacked or own with A15 products to reinforce contour and extend bandwidth to 29 Hz.
