RCF P 3115T Description

The RCF P 3115T is a full-range, coaxial two-way speaker system engineered for permanent outdoor and indoor installations requiring high output, wide dispersion, and weather resistance. Its coaxial design ensures consistent sound quality and uniform coverage, whether installed individually or in array configurations. Delivering up to 129 dB SPL, it is ideal for speech, music playback, and paging in large-scale applications. Internally, the speaker features a 15" woofer with a 3" voice coil and a centrally-mounted 1.3" neodymium compression driver on a CMD (Coverage Matching Design) horn, resulting in coherent phase alignment and smooth frequency response. The integrated 100V transformer with selectable power taps allows for flexible use in distributed audio systems. Housed in a single-piece roto-molded polyethylene enclosure, the P 3115T is fully UV protected and meets IP55 environmental standards. Its corrosion-resistant aluminum grille and 316L stainless steel U-bracket make it an ideal solution for long-term outdoor exposure. RCF’s LICC crossover and AMCDP protection ensure optimal performance and longevity, even under demanding conditions.
