RCF NX 12-SMA – A Solid Choice For Home Recording Studio Pros

You’re a musician and you want to make sure that your sound is as good as it can be. RCF NX 12-SMA is perfect for you.

The problem with most stage monitors is that they don’t have the power or frequency range needed for live performances in smaller venues. This means that musicians often end up sounding off-key, out of tune, or just plain bad when performing on stage.

RCF NX 12-SMA Active Coaxial Stage Monitor solves this problem by using active coaxial technology which provides an extremely wide frequency range and plenty of power for any performance situation. It’s also perfect for home recording studios because it has a solid build quality and doesn’t need to be connected to a separate amplifier like other stage monitors.

RCF NX 12-SMA Reviews 2024


The RCF NX 12-SMA is a strong, adaptable monitor that can be used as a floor or PA system, and its accessories match that versatility.

It has a 700 W digital amplifier and two EQ modes: one for stage monitoring and one for PA use. A lever on the front of the speaker instantly switches between the two EQ modes.

Coaxial transducers provide very excellent sound quality with no feedback, which typical monitors with speakers can not provide. The coaxial neodymium transducers use a coherent single spherical wavefront with dispersion adjustment, allowing the monitors to be deployed anywhere on stage.

For those who enjoy customizing their gear, the NX 12-SMA includes a hyper venting basket for the transducers, which allows for maximum cooling and less power compression.

The integrated DSP board includes an input sensitivity switch, a free field-floor switch, power con AC input and output, speaker cable direct link XLR & jack input connectors, and status LEDs.

The belt-pack remote that comes with its speaker includes power, gain, and three EQ presets that can be used as an additional interface for tailoring your sound.

The powder-coated finish on the NX 12-SMA speakers is elegant and available in a number of colors. The cabinets are constructed of Baltic Birch Plywood and coated with durable paint to withstand long-term use on the road. These cabinets include an ergonomic side handle built into the input panel to aid with moving.

The integrated wide dispersion, high output transducers of the NX 12-SMA provide very smooth frequency response. You may easily utilize them as floor monitors or PA speakers thanks to their 1,400 peak watt output and 700 RMS wattage.

Finally, the RCF NX 12-SMA is a powerful monitor that can function as a floor or PA system. I really enjoyed using this speaker. It was a lot of fun and I felt like it had amazing sound quality! I would love to use it again.


  • Strong body design
  • Very good sound quality

Factors To Consider When Choosing RCF NX 12-SMA

RCF NX 12-SMA Active Coaxial Stage Monitors are the perfect solution for those who require a compact, high-performance speaker. Here are 5 things that you should think about before choosing the RCF NX 12-SMA:

1. Monitor Size

NX 12-SMA is a small active analog tube monitor, weighing in at less than 0.5kg and measuring 31mm x 22mm x 13mm. It offers the advantage of being the smallest and lightest SMA unit on the market with such high performance. The NX 12-SMA is available in five sizes with intervals of 20mm (from 11-33mm).

2. Frequency Range

The frequency range offers a significant advantage to users; we can choose from 20Hz to 20kHz with a resolution of 2dB and 4dB respectively.

The bandwidth is very wide and covers all ranges that most microphones or musical instruments produce while maintaining low noise levels at all frequencies. The NX 12-SMA has a very sweet high-frequency response with the lowest feedback rate in its class.

3. Impedance

The impedance can be set to 8 or 75 ohms via an accessible switch on top of the monitor, depending on the requirements of the audio source and system that is being used.

4. Power Requirements

The NX 12-SMA needs a single external 24V DC supply with a maximum current of 100mA. The monitor can operate from 12 to 30V, and will automatically regulate the power supply voltage when connected to a specific power source in order to work at optimal performance.

5. Tube

The tube is a 12AX7 amplifier that uses a fully regulated DC power supply and has an integrated audio transformer. The power supply, tube, and output transformer are all housed in the same box as the electronics. High voltage capacitors ensure efficient filtering of any noise produced by the monitor.

This monitor will work on any sound system!

FAQs about RCF NX 12-SMA

rcf nx 12-sma

Is this product suitable for beginners?

Yes, it is! It’s not just suitable for beginners, but perfect for the budding music producer and DJ. There are loads of features including a headphone socket with volume control and impedance selector switch. And with twelve-inch speakers, the sound quality you get will be second to none.

This might not sound like much at first glance, but we think it’ll make your audio production wizardry worth its weight in gold dust! We’ve got three full octaves of frequencies here with a lot more low-end punch than one normally gets from such a small body design.

The monitors also provide great detail in the high frequency – which is essential for any musician or music producer; they’re also capable of recreating an impressive amount of power and dynamics too.

Does the RCF NX 12-SMA have an adjustable tweeter?

Yes, the RCF NX 12 has an adjustable tweeter.

The best thing about this monitor though is the sound quality! With its great bass response and its amazingly detailed, clear sound, you’ll never need to worry about not being able to hear what your bandmates are doing.

We all know how annoying it can be when someone else in the band who has a different monitor setup is too loud or too muffled for you to make out their performance. It can be really frustrating at times when that happens- which is why having some adjustability on your end would come really handy!

You won’t have that problem here because there are both high pass filters as well as low pass filters on this monitor’s very capable 18dB crossover network.

Can I install it with a ceiling mount system?

rcf nx 12-sma

It is designed to be mounted on a 10ft. fly system with extension arms and can also be suspended from trusses at various angles.

With the RCF NX monitor, you can set up an installation that works for your needs – whether that’s saving floor space or providing more accurate coverage for what your venue’s situation calls for.

The monitor can be hung from chains and cables via z-clips and comes with appropriate hanging hardware needed to accommodate 45° and 90° ceiling outlet patterns.

To make it easier to install these monitors, the company includes several different types of mounting points as well as slack absorbing material strung through each panel to help maintain stability during transport.

Even if you’re installing the monitors by yourself, they’re actually quite easy to set up and break down.

Is there any limit to how high I can stand on top of it before the sound quality degrades over time?

The sound will degrade over time. Before playing any music, please ensure that the speaker is turned off or on standby mode.

The RCF NX 12-SMA Active Coaxial Stage Monitor is a speaker with a twelve-inch driver and no passive crossover network in its design.

The speakers were designed to offer usable high frequencies when placed close to the floor; thus they must be used up above head level when placed at stage levels in order to avoid undesirable property and coloration of upper-frequency response.

Therefore there is no limit to how high you can stand on top of it before the sound quality degrades over time because it’s not designed for that which we use up above head level.

This active monitor has a wide range, can’t I just use it for recording purposes too?

The RCF NX 12-SMA is an active, monitor loudspeaker system that can be used for “stage monitoring” or as part of a complete sound reinforcement system. The underlying requirements are the same regardless of the application: it needs to cover a broad frequency range (28 Hz – 31 kHz) with low distortion and high efficiency (90dB), also known as “linearity”.

This unit will make an ideal stage monitor because its large size covers the entire required 28Hz-31kHz frequency range, producing deep bass without adding resonances or other distortions. The speaker’s power output makes it easy to fill larger sounding areas like halls and auditoriums with big, even coverage.

One power amplifier drives all four speakers simultaneously; that means that the NX 12-SMA needs only one power supply, one AC connection, and minimal cabling. The active crossover makes setup easy where each driver is connected to the amplifier driving the appropriate frequency range.

The NX 12-SMA may be used for applications other than stage monitoring; where high output in a relatively small enclosure is called for, as in the recording studio or smaller venues. In these applications, it can be used as a conventional PA enclosure by adding one or two high-quality subwoofers.

The complete system is composed of four NX 12-SMA active monitors and any number of NX 10-SUB passive subwoofers for an extended low-frequency response. The NX 12-SMA is born ready to work with other NX series active components and will easily integrate into any NX system without requiring crossovers.

Can you use the RCF NX 12-SMA for anything else besides sound and lighting?

Yes, you can also use RCF NX12-SMA for computers IF the speakers are not needed.

OR, The RCF NX 12-SMA headset is made with noise-canceling features which provide an optimal audio experience even in tough conditions. You can use these headphones to play games or stream music at home or on the go.

Do audio enthusiasts want to know if this product will be able to pair with other system inputs like Bluetooth-compatible devices? Music lovers who don’t have time to download their favorite tunes before heading out of town will enjoy being able to load up their favorites on a tablet and take off.

These speakers are lightweight and rugged enough that they can hang along securely without risking damage normally associated with portable sound systems. They are rechargeable and the manufacturer offers a 3-year warranty to go with them.
