RCF NX 915-SMA - 2100W 15-inch Powered 2-Way Stage Monitor with 100 x 70-Degree Coverage in Black Finish

The RCF NX 915-SMA is a powerful and versatile 15-inch powered 2-way stage monitor, engineered for sound providers, musicians, bands, and DJs who demand exceptional audio performance. Featuring a combination of a 1.75" compression driver, a 15" woofer, and a two-channel 2,100W Class-D amplifier, the NX 915-SMA offers coherent 100° x 70° coverage for the listening area with up to 131 dB SPL of distortion-free sound. This high-performance speaker is perfect for use as a stage monitor, stand-alone FOH system, or satellite speaker paired with a subwoofer, providing deep, impactful bass and clear high frequencies across the entire frequency range.

RCF's NX 915-SMA integrates proprietary FiRPHASE zero-degree phase technology, ensuring minimal phase distortion and providing a transparent, natural sound across all frequencies. The Bass Motion Control (BMC) DSP processing feature ensures the woofer maintains stability even during extended bass frequencies, delivering a clear and accurate sound with extended linearity. This combination of FiRPHASE and BMC allows the NX 915-SMA to produce exceptionally clear and powerful audio with perfect imaging, ideal for both live performances and installations.

At the heart of the NX 915-SMA is a 2,100W Class-D amplifier, which delivers ultra-fast transient response and a high SPL output while maintaining low heat generation and energy efficiency. The amplifier's design, combined with an aluminum heat exchanger, ensures quiet, fan-less operation while providing reliable power to the speaker. RCF's advanced input circuit features a low-distortion design with an advanced safety limiter, which preserves the integrity of the input signal at all output levels. All components are designed for maximum safety and longevity, in line with EN62368-1 standards.

The NX 915-SMA is built with RCF's renowned craftsmanship and durability. The rugged all-wood cabinet features a durable steel grille and is designed for easy transport with side and top handles. The speaker is also equipped with multiple M10 rigging points for flexible installation, allowing it to be flown, wall-mounted, or pole-mounted for various live sound applications. The speaker's 35mm pole mount socket makes it suitable for use as a stand-alone speaker or paired with a subwoofer for extended bass response.

This versatile speaker is particularly suited for high-power, pristine sound output and can easily transition between being a main FOH speaker or a stage monitor, making it ideal for musicians and live performances. The NX 915-SMA can also handle a range of guitar and bass applications thanks to its Full Range Flat Response (FRFR), providing a neutral, transparent sound that enables modeling through digital processors with complete freedom and power. Its wide frequency response of 45 Hz to 20,000 Hz, combined with a maximum SPL of 131 dB, makes it the perfect choice for small to medium-sized venues and touring setups.
