Compact and lightweight, the Pure Resonance Audio C3 3" micro ceiling speaker system is an intelligent, stylish design that seamlessly blends into ceilings while producing quality sound and excellent dispersion of both music and vocals. Because of its small size, the C3 ceiling speaker is great for installations where architectural or aesthetic considerations require a small format ceiling speaker. It features an 8 Ohm and 70 Volt tap, as well as a power tap transformer switch which allows for selectable inputs of 8 Ohm or 70V/100V applications. The C3 ceiling speaker is perfect for providing background music, paging and ambient sound masking for offices, retail stores, coffee shops, restaurants, hospitality venues, reception/waiting rooms, lounges, foyers, hallways, and auxiliary spaces.
