Simply classic

The nuLine 284 is a milestone in speaker technology. Thanks to elaborate woofers, the flat diaphragm for the midrange and the nuOva tweeter, it is possible to create a sound design that is unparalleled at 113 cm height and 18 cm cabinet width. In the bass, 33 Hz lower cutoff frequency results in a remarkable volume, which is complemented by the midrange driver and tweeter with details and clarity.

Made for stereo

The nuLine 284 achieves a new level of sound detail, making it a clear recommendation for your dream of a high-performance, visually appealing hi-fi system.

At home in the home theater

In the home theater, the nuLine 284 finds a suitable playing partner in the nuLine CS-174 which also relies on 3-way for a maximally homogeneous home theater experience.

Modern 2.1 set

The nuLine 284 comes down to 33 Hz. If that's not enough, the nuSub XW-900 and the XW-1200 from the nuSub-Series offer significantly more bass.

Complete in set

With the matching amplifier nuConnect ampX, the nuLine 284 becomes a customizable and modern system with sufficient power. Our other sets are also more than worth a look.


nuOva tweeter

In the nuLine 284, the tweeter is separated at 2,150 Hz. The nuOva tweeter is a sophisticated high-tech product that has been optimized for minimal resonance. Mainly responsible for this is the damped rear volume chamber, which thus ensures very fast decay. Your advantage: More details and a clear reproduction of music.


The midrange driver of the nuLine 284 operates seamlessly below the tweeter in the range from 33 Hz to 23,000 Hz. It uses a flat diaphragm with a compact diameter that combines detailed mids and homogeneous omnidirectional response. Another big advantage is the interaction with the tweeter, which can work even better due to the almost flush surfaces. Your advantage: impressive voice reproduction with precise localization.


The woofer of the nuLine 284 reproduces the bass part of the music or movie and thus relieves the midrange driver. The longstroke technology in combination with a bass reflex port, the speaker can reproduce a lower cutoff frequency of 33 Hz at almost full level. Your advantage: controlled and linear bass reproduction at all volumes.


The crossover is the control center and heart of the nuLine 284. Durable components ensure accurate reproduction and linear sound for decades. The switches on the back directly influence the crossover, allowing seamless switching between direct or dipole mode. In addition, the crossover features self-resetting fuses that protect the drivers from overload.


Our nuLine series relies on the high-quality lacquer finishes black and white, which are applied in several layers and sanded again and again for a perfect surface finish with a softline edge. The third option is a real highlight: the real wood veneer in walnut. This makes every model a real one-of-a-kind.


In the nuLine series, clear shapes with delicate softline curves give the models a timeless elegance. Acoustic considerations are also at the forefront of the design process, as slightly rounded edges ensure less edge dispersion, as does the asymmetrical arrangement of the tweeters. This is matched by the elaborately calculated metal grille, which has hardly any measurable effect on the sound.

Series overview

Our nuLine series is not only Made in Germany, but also committed to honest sound: All speakers reproduce music neutrally and thus exactly as it was recorded. What's more, with 10 models in this series, we have the greatest variety for all applications, from wall or ceiling speakers, compact and floorstanding speakers to the Dolby Atmos-certified add-on speaker nuLine RS-54.

What an acoustic pleasure

Technische Informationen

Subject to technical changes.

Box type and recommended use

The nuLine 284 is a successful example of how a floorstanding speaker with a height of just under 115 centimetres and a weight of around 30 kilograms does not have to appear bulky or even clunky. In fact, the opposite is true. With a width of only 18 centimetres, the nuLine 284 has to be described as dainty in relation to its size - after all, our small compact speakers are only marginally narrower. Despite these extremely living-room-friendly dimensions, the nuLine 284 has performance parameters that simply put the fear of God into many much more voluminous models. A peak power handling of 450 watts and a subwoofer-like bass of 33 Hertz will make any ambitious music lover sit up and take notice. The speakers of the nuLine series are developed in Schwäbisch Gmünd and manufactured according to our specifications at a traditional specialist company for sound furniture construction in Germany.

Construction principle and housing

Three-way floorstanding speaker in bass reflex design. The bass reflex port is located at the rear of the cabinet, which is why the speaker should be placed at least 3 centimetres away from a rear wall. The high sound quality of the nuLine 284 is realised with the filter optimisation based on the three-way principle taken from our top series nuVero. In this way, the development team Günther Nubert and Thomas Bien succeeded in significantly increasing the sound purity of conventional three-way designs, especially in the critical mid-range, while at the same time exploiting the fundamental advantage of a more even horizontal dispersion pattern. The very elaborately manufactured cabinet is made of 19 to 38 mm thick veneered or multi-layer lacquered MDF material and is manufactured by an experienced sound furniture specialist in Germany. It has precisely calculated internal stiffeners and damping elements, which effectively reinforce the stability of the already quite solid cabinet walls and effectively prevent sound-damaging natural resonances. To ensure that the rear sound components of the woofers and the midrange driver do not interfere with each other, the midrange driver has its own, acoustically precisely tuned inner cabinet. The elegant solid metal crossbar feet give the speaker a delicate appearance and a stable stand.


In the tweeter range, the nuOva tweeter, newly developed for our nuLine series, is used with special sound guidance and a specially damped rear volume chamber. Its oval front plate makes it possible to further increase the difference in distance between the dome and the cabinet edges compared to the previous asymmetrical Nubert tweeters, which further reduces edge dispersion in the axial direction and noticeably increases clarity in the high frequency range. At the same time, the driver can be moved closer to the mid/bass driver in the perpendicular direction, which is in line with the ideal of a point source without having to accept the disadvantages of a coaxial system. The asymmetrical arrangement of the tweeters means that a "right" and a "left" speaker is always supplied.

Midrange speaker

For the first time Nubert uses a flat diaphragm chassis. At the beginning of the development work, it was confirmed that flat diaphragms were more susceptible to disturbing partial vibrations than similarly sized cone diaphragms. By fine-tuning multi-layer diaphragms that have a honeycomb structure (honeycomb technology), it was possible to shift the disturbing natural resonances step by step to much higher frequency ranges where the radiation is almost completely through the tweeter. Unlike cone speakers, the majority of this optimised midrange driver is flush with the baffle, creating a favourable environment for the adjacent tweeter, which benefits the dispersion characteristics.


Another new development is the 15-centimetre long-stroke woofer, three of which are used in the nuLine 284 floorstanding speaker. This high-tech driver, equipped with a double magnet, enables an optimum ratio of large cone excursion, maximum bass response and amplifier-friendly efficiency. The result is a heavy-duty long-stroke woofer with a polypropylene diaphragm that can deflect up to 20 mm in extreme cases. The six woofers of a pair of nuLine 284 together correspond to the diaphragm area of a stately subwoofer with 30 cm drivers, which makes it clear why this speaker has such a deep and powerful bass foundation. Furthermore, the vertical arrangement of the woofers reduces the occurrence of room resonances (technical term "modes") between the floor and the ceiling.


The crossover of the nuLine 284 is a masterpiece in itself when it comes to filter technology. Here, the signals arriving from the amplifier are divided into three frequency ranges with particular precision using special crossover technology, while the drivers receive their final sonic polish via sophisticated compensation circuits.

In order to be able to realise the quality demands typical of Nubert, no less than 35 high-quality components were necessary, including close-tolerance film capacitors in the midrange and treble range.

The low crossover frequency at 2.2 kHz frees the midrange driver from higher frequencies and, in conjunction with the deliberately small design, ensures exceptionally wide dispersion. An efficient protection circuit watches over the safety of the drivers and the crossover. If there is a risk of thermal overload, it cuts the amplifier current and automatically returns to normal operation once the danger has passed.

Switching options

The upper switch between the terminals of the terminal allows a threefold modification of the high-frequency range from "soft" to "neutral" to "brilliant", which allows the speaker to be individually adapted to different living rooms with more or less textile sound damping or personal listening preferences. With the second tone selector switch, the bass level can be moderately lowered. This switch variant ensures that an undesired increase in the bass level can be compensated for when the speaker is placed close to a wall.

Connection terminal

The extremely solid, gold-plated screw terminals of the bi-wiring terminal are also suitable for cables with a very large cross-section. Bi-wiring terminals allow the tweeter and low/midrange to be connected separately to the amplifier. A measure that can prevent sound loss with long cable lengths. In addition, the sound selector switches described above are located on the terminal.
