The Perfect Performing Companion
Enjoy a cleaner monitor mix the next time you perform with the RCF NX 912-SMA professional active stage monitor. Its compact and unobtrusive profile effortlessly blends in onstage. The speaker is loaded with a 12-inch woofer and a matching 1.75-inch compression driver. Those drivers, combined with the Bass Motion Control and FiRPHASE technology under the hood, supply clean and clear sound free of phase distortion and latency. While it’s designed as a stage monitor, RCF tells Sweetwater that the NX 912-SMA can also be used as an all-in-one loudspeaker or as a top box with a subwoofer. Purchase two RCF NX 912-SMA professional active stage monitors and perform with total confidence.
FiRPHASE technology for maximum transparency
RCF equipped the NX 912-SMA with its cutting-edge FiRPHASE technology. This technology uses advanced FiR (Finite Impulse Response) that delivers 0-degree linear phase playback. The highly advanced FiRPHASE technology helps the NX 912-SMA deliver outrageously coherent sound to your ears with no phase distortion and imperceptible latency. Elevate your onstage monitoring experience with the RCF NX 912-SMA’s FiRPHASE technology.


Reinforce your low end with Bass Motion Control
Most loudspeakers use highpass filters to help stabilize and optimize woofer performance. Instead, RCF’s design team outfitted the NX 912-SMA with BMC (Bass Motion Control). BMC uses unique DSP to ensure woofer stability all the way down to the lowest possible frequencies. BMC creates a map of the woofer’s dynamic behavior and generates a custom algorithm that only limits over-excursion. With the Bass Motion Control functionality, you get robust bass that other floor monitors simply can’t replicate.
Three ways to use it
You can use the NX 912-SMA in three ways. Of course, it’s dynamite as a stage monitor. When you’re not performing onstage, you can use the NX 912-SMA as a standalone portable PA system for music playback. What about situations where you need more bass? No problem. Use the built-in pole mount socket and mount it above a subwoofer for a full-range response. However you use it, the NX 912-SMA’s impressive sound and consistent coverage are sure to impress.
