Stereo speakers

The nuBoxx B-70 is a stereo dream speaker that technically goes far beyond the entry-level class. Three-way technology paired with our state-of-the-art drivers developed in-house ensure more sound fascination with music.

nuBoxx B-70 Surround

Surround speakers

The three-way technology provides more details in the voice reproduction and a wider dynamic range. A dream for your new surround setup. With 30 Hz lower cut-off frequency, the nuBoxx B-70 can also demonstrate its capabilities without a subwoofer.

nuBoxx B-70 Anlage

Smart HiFi system

Together with the nuConnect ampX, the nuBoxx becomes a powerful hi-fi system with a modern measuring function that leaves little to be desired. In the set you can secure a saving, so it's worth taking action.

Housing

We recommend using a standard glass cleaner sprayed onto a cotton cloth. This allows most fingerprints and dirt to be removed easily. Alternatively, you can use window active foam. We advise against using microfiber cloths as they may cause micro-scratches on the surface.

Membranes and Speaker Drivers

To remove dust from a speaker driver, use a lint-free cotton cloth and gently wipe the membrane with very light pressure. All Nubert speakers' tweeters are protected by a grille, which can also be wiped lightly with minimal pressure. If the dust cannot be completely removed, a makeup brush from the drugstore can be used.

Technical information

Box type, sound and recommended use

As the top model in the series, the nuBoxx B-70 sets several records at once: No other nuBoxx is so powerful and level, so resolutely tone-setting, plays so profoundly and honestly. For the first time, our engineers have succeeded in establishing a fully-fledged three-way system in our entry-level series, creating a floorstanding loudspeaker that achieves unprecedented acoustic excellence in this class at a surprisingly affordable price.

As a full-grown floorstanding speaker, the nuBoxx B-70 knows how to make use of generous room conditions, bridges even wide listening distances and benefits from the powerful output stages of our nuConnect and nuPower amplifiers. Highly resilient and efficient, the nuBoxx B-70 comes up trumps even at party-suitable levels, but also knows how to bring quiet sounds to the ear authentically and with great detail.

It benefits from the elaborate three-way principle that reproduces mids, highs and basses precisely and evenly, from the overwhelmingly low lower cut-off frequency, which at 32 Hertz (at -3 decibels) is close to the threshold of human hearing, to the pleasantly finely resolved super high frequency range. The nuOva-B dome tweeter with nuLine technology shines not only with outstanding fine detail, but also with optimum omnidirectional sound dispersion, which makes an optimal listening experience across a wide area a reality. The 123-millimetre driver, which is also used in the wall-mounted speaker, ensures optimum dispersion characteristics and high efficiency. In combination with the elaborate crossover and the custom-made cabinet, the above-mentioned characteristics lead to an outstandingly natural and impressively spatial appearance that does not lose its fascination even when sitting far beyond the apex of the stereo triangle.

Even without an additional subwoofer, the nuBoxx B-70 promises cinema-quality film enjoyment in home cinema use and enchants even ambitious listeners as a sound transducer for a stereo system. Professionals can rely on the nuBoxx B-70 as a neutral passive monitoring solution. If you are looking for maximum sound enjoyment for a manageable investment, the nuBoxx B-70 is the right choice.

Construction principle/housing

Three-way floorstanding loudspeaker in bass reflex design. The 19 to 38 millimetre thick cabinet walls are made of acoustically advantageous and robust wood fibre material (MDF). Precisely calculated internal bracing not only increases the mechanical stability of the construction, but above all suppresses resonances that are harmful to the sound. While the baffle is finished in a satin matt graphite or ice grey lacquer, the cabinet body is finished in a high quality, durable black or white decorative film. The removable front cover is covered in light or dark grey mottled acoustic fabric and is magnetically attached, so there are no visible brackets to detract from the elegant appearance. A secure stand is ensured by the rectangular base.

Chassis

The nuBoxx B-70 is equipped with a 26 millimetre tweeter (nuOva B), a 123 millimetre midrange driver and two 180 millimetre woofers (B² technology).

All nuBoxx models rely on the same silk-fabric tweeter dome, developed on the basis of the advanced nuOva chassis of the nuLine series and christened nuOva B. A multi-layered damped rear chamber volume behind the oscillating system ensures a particularly harmonious frequency transition to the bass-midrange driver, while the carefully designed and precisely manufactured front panel with wide-dispersion sound guidance optimises the dispersion characteristics and fine detailing of the super-high frequency range above 7 kilohertz. As a result, the new nuBoxx tweeter sets standards in terms of resolving power and allows the audience to enjoy maximum listening pleasure even outside the narrowly defined "sweet spot".

The two 180-millimetre woofers with polypropylene cone rely on a particularly strong and responsive magnetic drive. Its streamlined design and the generous rear ventilation of the spider avoid compression effects and cool the extra-long voice coil under high continuous load. Due to the particularly wide and flexible diaphragm clamping with a low fundamental resonance, the maximum linear excursion could be significantly increased compared to previous driver models, which enables a particularly profound and level-fixed bass reproduction. The total excursion of the woofer is almost three centimetres. Special design measures also prevent the diaphragm from "breaking up" at higher frequencies (keyword: partial vibrations), despite its robust suspension.

As the only three-way design in the nuBoxx series, the B-70 also uses a midrange driver with a diameter of 123 millimetres (which acts as a woofer in the BF-10 wall-mounted speaker). This driver is characterised by minimal distortion values and minimal resonances, especially in the limited midrange spectrum. The comparatively small diaphragm area ensures a particularly good omnidirectional sound distribution. The amplified drive brings the efficiency to the level of the powerful woofers.

Crossover

The crossover separates the signal paths, linearises the driver systems and optimises the impulse and phase. As usual with Nubert, the circuit board is above average and equipped with long-term stable film capacitors at the sound-critical points. The three-way design of the B-70 demands particularly careful tuning and sophisticated harmonisation of all drivers. A reliable protection circuit cuts off the amplifier current to the chassis and crossover in the event of an impending overload and then automatically resets itself to normal operation.

Connection terminal

All nuBoxx speakers are equipped with a completely redesigned connection terminal, which is precisely recessed in the lower area of the rear panel. The bi-wiring terminal of previous nuBox generations, which is rarely used in the entry-level class, has been replaced by two high-quality angled screw terminals with precision threads, which now also offer banana plugs a secure hold and an optimum contact surface.
