The QSC AD-P.HALO is a purpose-built, integrated SUB/SAT pendant loudspeaker system, featuring one 6.5" subwoofer and four 2.75" satellite transducers in a single enclosure that is ready to install out of the box. Designed for business music installations where music drives the atmosphere. All-in-One Solution, No Assembly Required Contrary to their name, some "all-in-one" solutions often requiring time-consuming assembly of multiple components. Instead, the AD-P.HALO is purpose-designed and fully integrated within a single-enclosure pendant that is ready to hang right out of the box. This hassle-free design simplifies and expedites the installation process and lowers the overall project costs and allows the integrator to focus on the sound.
