Ultra compact self-powered subwoofer equipped with one (1) speaker of 15" in a tuned enclosure. IT-A 115 B is an excellent low reinforcement for the different systems from the IT-A Series. The perfect solution as compact P.A. in small and medium outdoor events, or permanent installation. Since it is a subwoofer, the transducer configuration generates an omnidirectional audio projection.

IT-A 115 B incorporates a new Class-D amplification module to amplify itself and another passive unit IT 1M6 i, IT 1M6 L.A. IT 2M6 ii 403, i 803M 10, or M 12 which allows making infinite ultra compact configurations.
