The L-Acoustics A15 Focus + KS21 + LA4X Kit combines a compact constant-curvature loudspeaker, a high-impact subwoofer and a trusted amplified controller for powerful, controlled reinforcement. A15 Focus delivers tight 10° vertical coverage with Panflex directivity for symmetrical 70°/110° or asymmetric 90° patterns, maintaining a stable frequency response across the audience. With up to 144 dB SPL and throw up to 45 metres, it excels as a standalone point source or in vertical lines, and can be paired with A15 Wide when broader coverage is needed. The KS21 sub extends bandwidth down to around 29 Hz, adding punch and low-end contour worthy of larger touring systems. Driven by the LA4X amplified controller for optimised presets and protection, the system ensures consistent tonal balance and reliable performance. Rugged Baltic birch construction, IP55 rating and proven L-Acoustics rigging make it ready for demanding shows and outdoor use. This kit includes: A15 Focus loudspeaker, KS21 subwoofer and LA4X amplified controller. Ideal for touring, festivals, corporate events and high-impact installs requiring premium clarity, throw and flexible coverage.
