The H1315 Three-Way Passive Speaker from RCF is a three-way full range loudspeaker system that incorporate a 15" LF transducer, a 10" cone MF transducer, and a 1.4" exit titanium compression driver. The speaker system is compact, provides high output and accurate voice & sound reproduction, and uses a SPEAKON connector. The LF driver, equipped with a 4" voice coil and a neodymium motor, is mounted in a vented enclosure with optimized front loading. The MF cone driver is a unique RCF sealed basket design and is loaded into an exponential, Baltic birch 60° x 40° midrange horn. The 3" coil MF driver is acoustically equalized due to a RCF complex phase-plug design. The HF titanium compression driver is loaded on a constant directivity rotatable horn with a coverage of 60° x 40°.

The internal crossover network between midrange and compression driver offers compression driver protection due to an Active MOSFET Circuit. The system is driven in bi-amped mode, is capable of producing a Max SPL higher than 136 dB, and handles 900 W AES (LF) + 400 W AES (MF/HF). The loudspeaker enclosure shape is multi-trapezoidal, and allows a double coupling angle on each side.

The cabinet of the H1315 is constructed of multi-ply Baltic birch plywood, and finished in a resistant and textured polyurethane black paint. It includes 2 recessed handles for transportation and positioning, and a total of six double M10 fixing points for flown applications and extensive internal metal bracing. The front steel grille is epoxy powder coated.
