nuVero 170

Box type and recommendations for use

With the nuVero 170, we present the top model of this award-winning series and the best direct radiator in our entire range. While Günther Nubert had perfected the three-way principle for the first nuVero generation, the nuVero 170 is the first four-way speaker from our house. The reproduction spectrum is divided into four sections: Bass, Treble and a lower and an upper midrange branch. This has several advantages: Firstly, it allows each driver to work in its optimal range, which avoids partial vibrations that damage the sound. Secondly, it minimises bundling effects. The sound spreads evenly in the room, which results in an audible "airiness" of the reproduction, which is also maintained well outside the "sweet spot" for the listener. The symmetrical driver arrangement also reduces the excitation of room modes and thus the risk of noise interference such as booming. As a pleasant side effect, the acoustic centre of the nuVero 170 can be easily localised, allowing precise location of phantom sound sources. To put it more simply: Nubert's flagship delights with its particularly spatial stereo stage and its precise, three-dimensional sound imaging. The enormous effort put into the development, construction and use of materials of the nuVero 170 is reflected in a uniquely honest and neutral sound reproduction - and thus a "lightness" and "effortlessness" of playback that has probably never been achieved before. If you can enjoy music with the nuVero 170, new "listening horizons" will indeed open up.

The speakers of the nuVero series are developed in Schwäbisch Gmünd and manufactured according to our specifications at a traditional specialist company for sound furniture construction in Germany.

Tweeter

Designed from the ground up, the silk fabric dome extends the speaker's phenomenal resolving power even further, achieving unprecedented transparency and audibility in the upper frequency range. The 26-millimetre tweeter is arranged asymmetrically, so there are dedicated boxes for right and left.

Mid-range tweeter

For the upper midrange, the nuVero 170 relies on two compact midrange drivers with an effective diaphragm diameter of only 52 millimetres, which are characterised by excellent omnidirectional sound dispersion. The flat diaphragm chassis is supported by a torsion-resistant die-cast aluminium basket with generous ventilation openings. Thanks to the powerful neodymium drive and the resilient voice coil, impressive levels can be achieved despite the small size.

Low-midrange speaker

The lower mids are handled by two 150-millimetre drivers in glass-fibre sandwich construction, which, thanks to their powerful magnet system, can deflect particularly precisely and powerfully. The two midrange drivers have a die-cast aluminium basket and a generously ventilated voice coil that eliminates flow noise. They have already proven themselves as woofers in the nuVero 110 and nuVero 70.

Woofer

In the low frequency range, the nuVero 170 achieves new record values: 23 Hertz at -3 decibels is a value that even many subwoofers are envious of. Our engineers were able to achieve this impressive result by using three ultra-long-throw woofers in 220-millimetre format that were specially developed for the nuVero 170 and which, thanks to their double centring surrounds, are extremely clean and controlled even at the highest excursions. Their strengths include a high-performance magnet system, a die-cast aluminium basket and a generously ventilated voice coil that eliminates flow noise.

Crossover

The crossover network optimally controls the drivers used. The filter network relies on high-quality components, including film capacitors with tight tolerances and long-term stability. A sophisticated protection circuit cuts the amplifier current to the chassis and crossover in the event of an impending overload and then automatically resets itself to normal operation.

Sound options

This loudspeaker is equipped with sound selector switches that allow the dispersion behaviour to be adjusted to the environment or personal listening taste with a simple flick of the wrist. The high-frequency range can be tuned to "neutral", "brilliant" or "soft" if desired. With another selector switch, the intensity of the mids can be lowered slightly, resulting in an audibly "warmer" sound image.

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. The terminal screws also allow optional speaker cable connection with banana plugs or nuCable Exclusiv. 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.

The bass range can be controlled via a suitable preamplifier such as the Nubert nuControl with a separate power amplifier and actively filtered (partial active mode), which enhances the low frequency performance.

Housing and design

The cabinet of the nuVero 170 is made of acoustically advantageous fibreboard (MDF) and has been elaborately braced and damped to avoid disturbing resonances. The elegantly curved sound sail on the front not only enriches the appearance, but at the same time minimises sound-damaging edge dispersion in the mid and high frequencies. A front grille - as standard on the other models - is not available on the nuVero 170 for technical and visual reasons.
