SLS MA460AS 3-Axis Speaker
Superior sound distribution for larger auditoriums
The SLS MA460AS is a high-power two-way loudspeaker, providing pan, tilt, and rotation capabilities for larger cinemas and auditoriums. The SLS MA460AS provides a 60° vertical x 60° – 150° asymmetrical horizontal dispersion pattern for more uniform coverage in all seating locations across the auditorium or theater.
Featuring a 400 W, 12” coaxial full-range speaker and passive crossover, the MA460AS is housed in a spherical-shaped molded enclosure that enables quick installation and easy three-axis aiming for fulfilling Dolby Atmos® aiming requirements.
The MA460AS was designed primarily for Dolby Atmos side surround applications, but can also be used for top surrounds in some cases. The MA480AS is also available if an 80°V x 80° – 130°H asymmetric dispersion pattern is desired.
