  • Available In 12" And 15" Versions To Suit A Range Of Cabinet Designs

The RCF CX-N351 series targets speaker system designers, cabinet builders, and installed sound integrators who need a true coaxial driver capable of performing as a single acoustic source. The integrated neodymium magnetic structure powers both the mid-bass woofer and the compression driver from one unified assembly, delivering coherent phase and time alignment that separate two-way systems cannot match. Available in 12" and 15" versions, the series accommodates a range of enclosure designs and coverage requirements, from compact installed monitor cabinets to larger full-range installs.

Each driver pairs a 3.5" inside-outside voice coil with dual-forced air ventilation and a demodulation ring, reducing thermal compression and distortion under sustained program levels. The compression driver uses a 0.05 mm pure titanium diaphragm and suspension with a 1.4" exit throat, covering the high-frequency band with low coloration from the crossover point through 20 kHz. The 60 x 60 degree symmetric dispersion horn is formed from structural polyurethane and is integrated directly into the coaxial assembly, making the CX-N351 series a practical choice for applications where predictable pattern control and compact installation depth are both priorities.

For integrators evaluating coaxial drivers against separate-component two-way designs, the CX-N351 series simplifies cabinet geometry, eliminates driver alignment variables, and delivers neodymium efficiency in a format that fits standard round baffle cutouts. CE compliance supports deployment in European-market projects alongside domestic installations.
