THX Ultra2™-Certified Multi-pole Configurable Surround Loudspeaker
From the industry leader in loudspeakers comes the problem-solving S4Ai multipurpose surround loudspeaker. It fits into standard-construction 2″ x 4″ stud walls with a grille that mounts flush to the wall surface, ensuring that even the toughest-to-please designers will love its look. Choose between dipole or bipole mode for a spectacular cinematic experience. Switch over to your favorite music mode and the S4Ai turns into a direct-radiating 2-way 8″ speaker. For smaller installations, where 7-channel sound is important but you don’t have the space, the S4Ai can be dual-driven to provide both side and rear channels from one position in the room. The S4Ai can be used with any of the JBL Synthesis Series systems.
