Nubert nuPro X-3000 RC Review

With the Nubert numero X-3000 RC, we would like to take a look at or listen to some higher-quality audio equipment for the PC today. In addition to some digital inputs, the active loudspeakers also have their own USB sound card and are therefore predestined to be operated on a computer.

The active series numero has been available since 2014 and has always been supplied with new models. The still fully wired and very popular GoPro A series was followed by the X series and recently the new generation with the suffix RC, for “room calibration”, ie active sound correction via a signal processor. But the interface has also been upgraded compared to the first generation of the X series, so the aptX-HD and AAC codec are now also included. Before I get to grips with the active transducers, first a brief overview of the complete technical data.

Detail view

I received the new X-3000 RC in the black version from Nubert, which looks very classy and discreet. Because together with the black transducers and the black front cover, the bookshelf speakers are quite inconspicuous in their appearance. If you need a little more contrast, simply use the white varnish variant. The case is very massive, the little rascals weigh almost seven kilograms and are superbly processed. Gaps, no visible screws, and a modern OLED display in the front clearly show what modern hi-fi or audio equipment should look like.

The fully active two-way box houses the dome newly designed for the X series with a diameter of 25 millimeters, the radiation behavior, and damping have been optimized compared to the dome from the A-series and the tweeter operates up to 22,000 Hertz. A bass-midrange driver with a diameter of 148mm is responsible for the mid-range and low-frequency range and should be able to play down to 38 Hertz; To ensure that the low-frequency range is also implemented in practice, the polypropylene composite membrane has a generously dimensioned bead to ensure large deflections. An OLED display including a control panel is located under the sound transducers for controlling and displaying various functions. Small side notes: Despite the dense acoustic material of the front panels, the new OLED display remains easy to read even at a distance of 2-3 meters.

Since these are active loudspeakers, no further amplifier technology is required for operation. Nubert does not act with a master-slave system such as B. the JBL One Series 104handle it, but in each loudspeaker, there is identical technology and you only have to define in the menu control which loudspeaker right or left has sound, but more on that later. The output stages of the X-3000 RC are on the back, as clearly indicated by the cooling fins of the amplification modules. Both chassis are driven by an active crossover and two digital amplifiers, each with 150 watts rated power. Another advantage of an active loudspeaker is the signal processing in the loudspeaker. In contrast to passive speakers, the signal with Nuberts X-3000 RC first passes through the DSP crossover and then goes to the integrated amplifier. This means that Nubert’s sound engineers can separate each frequency range from one another,

The topic of connectivity is also pushed at Nubert because there are some access points available for signal transmission. The digital interfaces have two optical, two coaxial, two USB ports (one is used for the HDMI module), and asymmetrical AES input. The analog section is a bit clearer, a balanced XLR input and an unbalanced stereo cinch input are available. All digital interfaces can with resolutions of up to 24 bit / 192kHzbypass and as already mentioned, a Bluetooth module 5.0 with aptX-HD is integrated for friends of wireless playback. Anyone who misses the connection between loudspeakers A and B is no longer there. Because the X series works wirelessly with each other, which in turn means that you define who of the two speakers is the master and connect all devices there. The second loudspeaker from this team receives the audio signals via wireless signal transmission and only requires a socket for operation.

Here, too, the loudspeakers operate at high resolution with 24-bit / 192 kHz and if you want to take the wireless system to the extreme, you can also use a preamp to map a home theater where the rear channels can be addressed wirelessly. I refer to my detailed article on the Nubert Wireless Surround with the X series. But other devices can also be integrated wirelessly, such as B. a subwoofer using the new Nubert connect to. As you can see, this system is extremely flexible and, next to the desk, also very interesting for hi-fi or home cinema fans. Before I get to the practical part of my review, I would like to express my praise for the included remote control. This offers a pleasant feel, with the rounded design picks up on the shape of the loudspeaker housing, and thanks to the aluminum top, it also has the necessary quality that you would expect.

Practice test and sound check

First of all, if you want to see the X-3000 in a hi-fi environment, you should read our article in the partner magazine: ( Test Nubert numero X-3000 ). I would like to concentrate here on desk use and show the practical benefits. The speakers are installed or set up quickly because all cables are included in the scope of delivery, even a high-quality USB cable for operation on my gaming PC is available. When plugged in, my Windows 10 computer automatically recognizes the active speakers as Nubert xCore USB audio devices, I don’t need to install drivers, so it’s child’s play and do. With the help of the menu, I connect both speakers by determining which of the “master” and who acts as the “slave” and then it can actually start.

But not so fast, because, as the “RC” in the name already suggests, the loudspeakers have integrated a “Room Calibration” called by Nubert. With the help of this, the lower frequency range is optimized or adapted to the conditions on-site. It small downer at this point, currently only works with iOS devices, Android users are still left out. The app itself is also available for Android devices and includes the same range of functions that can be accessed via the remote control and the menu buttons directly on the speaker.

Why the sound measurement or automatic sound optimization only works on iOS devices is quickly explained. Apple basically installs the same batches of microphones in their devices, so the values ​​can be reproduced with every device. Every manufacturer manufactures Android devices according to his own taste and therefore no reference can be determined for the developer of the software since all manufacturers use different hardware. A difficult subject, but Nubert is working on a solution, we have already been assured. If you were to supply a neutral microphone, as is the case with commercially available AV receivers, the problem would be solved, the hardware only has to be prepared for this. It’s a shame anyway because this feature works, in my case adjusted the bass range a bit or increased the depth, so that when playing or listening to music the sound had more power and dynamics. I also found the “behavior” of the low-frequency range to be a bit more precise and structured after calibration.

Android users are not completely empty-handed, because the Google version of the app also has manual tone control. The mid and high-frequency range, as well as the bass range, can be raised or lowered manually by 10dB and a five-fold equalizer is also available to the user to “bend” the sound.

The three presets are practical, especially when you are playing, working, and listening to music on your PC. The X-3000 RC can add powerful bass to the gaming experience, act neutrally in music or video production and play your favorite album audiophile. Depending on the intended use, the loudspeakers can be matched and prepared for three scenarios.

In terms of sound, the compact speakers on the desk are an experience. Not only do they cut a good figure as listening monitors, as they are very neutral at the factory and also generate a coherent stereo image at short distances and are therefore also a good choice for semi-professional music or video producers, but they can also really spread “fear and horror”, in a positive sense of course. With the right settings, one of the other first-person shooters becomes a real blockbuster and the neighbors also benefit from it.

Because even if the size does not suggest this at first glance, the compact models offer real bass that comes along with volume and pressure – and that up to really painful levels. Perfect for gamers who want to seriously experience their game not only visually, but also acoustically. This is also the strength of the X-3000 RC. Since you sit very close to the speakers at your desk, they do not have to generate so much power for a harmonious soundscape, but thanks to the loudness function they have a juicy depth that makes you want to go even at low volume. There is nothing more to say and I conclude.

Conclusion

The Nubert numero X-3000 RC is a great piece of hardware if I am allowed this subtle evaluation. Robert combines high-quality workmanship with modern technology, which has many practical features, all packaged in an excellently applied paint coat. Technically, the X-Series RC offers everything you would expect from an active loudspeaker of this category and even more. Many interfaces and connection options, current Bluetooth with aptX-HD, automatic sound optimization, which is currently only available for iOS devices, and intuitive control, whether via the app, the included remote control, or on the speaker itself. The entire work of the Swabians is consistent because the compact athletes are also convincing in terms of sound. High and midrange harmonize with each other, the bass range is powerful and dynamic, the Nubert numero X-3000 RC sound much more voluminous than they appear to be. I have come to this conclusion several times in the Nubert portfolio and also a clear advantage of active speakers with powerful hardware.

For the euro X-3000 RC, Nubert is asking for a unit price of 628 euros per loudspeaker. Certainly an investment at first glance. But real gamer enthusiasts who don’t shy away from high-end graphics cards or processors shouldn’t save on sound either. You should consider that the speakers presented here do not have to be replaced by a new generation every year to achieve higher frame rates (…). For me, an absolutely fair price structure for what is on offer and I pull out our gold award.

If you are looking for active speakers but don’t want to invest that much, you should take a closer look at the Nubert nuBox AS-125 or JBL One Series 104.
