RCF P 3115T W | 15in - 129 dB | IP55 Weatherproof Coaxial Speaker (100V/16Ω)

Weatherproof 15-inch coaxial loudspeaker for stadiums and large venues

RCF P 3115T W is a wide-dispersion, full-range coaxial two-way loudspeaker built for indoor/outdoor installations that demand clear speech and musicality at concert levels. Its IP55 cabinet, rotomolded for durability, pairs a 15" woofer with a coaxially mounted compression driver on a constant-directivity horn for even coverage and reliable performance in all weather.

RCF P 3115T W Description

The P 3115T W is purpose-built for large spaces—stadiums, arenas, theme parks, houses of worship, and civic venues—where consistent coverage and weather resistance are essential. Its coaxial topology aligns acoustic centers for coherent response, while RCF’s CMD geometry matches woofer and horn directivity for a seamless transition through the crossover region.

Installation is straightforward: the included 316L stainless steel U-bracket (with spacers) supports 90° mounting adjustments, and twelve M10 inserts expand rigging options. A built-in 100 V transformer with multiple power taps simplifies distributed audio deployments. With an IP55 rating, UV-stable enclosure, and water-repellent aluminum grille, the P 3115T delivers year-round reliability in demanding environments.
