L-Acoustics A15I-FOCUS: The Ultimate 15-Inch Passive Line Source Speaker for Medium Throw
Discover the A15i Focus, the installation version of the A15 Focus. It's designed for medium throw applications and offers identical sonic performance as its touring counterpart, with a sleeker design and streamlined mounting hardware for seamless integration.
• Tightly-controlled 10° coverage for powerful projection up to 45 m and an impressive 144 dB output.
• Panflex technology allows you to adapt directivity to the audience, ensuring exceptional frequency response stability.
• Versatile use: Combine with A15i Wide to form a vertical line source or use individually as a configurable point source for front fill or delay.
The A15i Focus provides the low frequency contour of a large concert system, and when paired with the KS21i subwoofer, it extends the bandwidth to 29 Hz. It's a discreet, powerful, and versatile solution with a wide range of install-specific accessories for theaters, houses of worship, clubs, convention centers, and sports venues.
