NX 945-A is masterfully engineered from the ground up to deliver stellar audio performance for sound providers, small bands and DJs. The combination of a 4" titanium/neodymium compression driver, 15" neodymium woofer - two-channel 2,100W amplifier, and the constant directivity True Resistive Waveguide produces coherent 100° x 70° coverage for the listening area with up to 135 dB SPL, distortion-free sound. Used as a stand-alone speaker for a FOH system, satellite (with subwoofer), stage monitor, or flown speaker, the NX 945-A blends high performance and reliability in a compact package. Merging RCF proprietary FiRPHASE and Bass Motion Control DSP processing, perfectly tuned for each model, the audience will experience absolute sound clarity and deep, powerful bass response. The tour-ready, rugged all-wood cabinet is easy to carry and secure to install on a pole-, flown-, wall-, or truss-mounted using the dedicated rigging points available.

Power that moves
The most powerful amplifier in its class. RCF's improvements in transducer design make them stronger and powerful, so the amplifier follows the evolution. With 2,100W of power, the 2-channel NX 9 Class-D amplifier is 50% more powerful than previous models, able to manage extreme sound pressure levels with an ultra-fast attack, realistic transient response, and very low heat loss. NX 9 is energy-efficient so there's no need for a cooling fan - the amplifier is attached to a solid aluminum heat exchanger in the rear of the cabinet without moving parts. The input circuit features a new low distortion design with an advanced safety limiter, maintaining the true character of the input signal at all levels. All NX 9 amplifiers are designed according to EN62368-1 for maximum safety and present a Switch Mode Power Supply section merging high-efficiency with minimum weight.

Legendary transducers

Potent woofer
The low-frequency transducer is a high-power 15’’ neodymium woofer with a 3.5’’ voice coil that delivers tight, punchy bass. Reproduction of the mid-bass frequencies is accurate, transparent, and free from distortion.

Superior compression drivers
The ND940 Compression Driver in pure Titanium with a 4-inch voice coil allows a crossover point at only 650 Hz. This allows a better impulse response, fast decay, and superior efficiency. Lightweight and powerful, RCF neodymium drivers are a reference in performance and reliability.

Direct Drive Technology
The voice coil features a high-temperature Kapton former. The assembly process takes advantage of the RCF proprietary Direct Drive technology. The diaphragm’s suspension has been designed following extensive research and development aimed at minimizing distortion and extending low-frequency range.

Bass Motion Control
When searching for extended bass with enhanced performance, RCF engineers found a way to remove the high-pass filter, replacing it with a forward-thinking approach. Introducing BMC (Bass Motion Control), the newly advanced woofer excursion management feature. NX 9 Series with BMC can handle the lowest audible frequencies without affecting the woofer stability, providing extended linearity and better sound integrity. The BMC method works by creating a complete map of the dynamic behavior of the woofer to generate a custom algorithm that only limits over-excursions. This gives total freedom of signal reproduction to the transducer. When high-pass filters normally protect the woofer motion from becoming destructive but change the phase behavior, the BMC algorithm breaks this rule. In combination with FiRPHASE technology, NX 9 has a new level of audio performance in this series of speakers.

Very spacious and beautiful
Size: 23.6 Inch, Color: White, Size: 23.6 Inch, Color: White
A lot of my books fit on here and there’s still more room left if I wanted to buy more books. It’s a simple looking bookshelf but it’s really pretty. It’s also sturdy the only reason I gave it a 4 stars instead of 5 was because it comes with its own plastic screw anchors and they are crap. The shelves were wobbly when we installed them using the plastic screw anchors that came with the packaging. My dad set mine up and luckily he had a bunch of his own so he switched them out with better screw anchors. Once we made that switch it was perfect, there was no wobble or shaking at all. So that’s my only piece of advice. Besides for the screw anchors everything else is perfect

Easy to install

Super easy to install. I use different wall anchors. The anchors like all anchors that come with shelves are not great. The shelves look very clean on the wall.

Easy to install

This product exceeded my expectations. The installation process was incredibly straightforward—even for someone with little to no experience—and the instructions were clear and easy to follow. Once installed, it feels very sturdy and secure, with no wobbling or shifting at all. You can tell it’s well-designed and made with quality materials. I also appreciated how quickly I was able to set everything up without needing any extra tools or help. Overall, it’s a reliable, user-friendly product that I would absolutely recommend to anyone looking for something dependable and easy to install. Drill is required though.

Don't buy
Size: 23.6 Inch, Color: White
The shelf is very flimsy and not sturdy at all. It feels unstable and poorly made. Definitely not worth the money, I wouldn’t recommend wasting your time or money on this product.
