Nubert nuPro AS-3500 – The new TV sound system

It is the latest addition to the Nubert nuPro series, as well as the latest solution from Nubert electronic GmbH, which is dedicated to the task of optimum sound when watching television, the new Nubert nuPro AS-3500. Although the manufacturer also refers to this as a soundbar, it has little to do with conventional soundbar systems.


The company Nubert electronic GmbH has been known for years as a proven loudspeaker and electronics specialist. In the field of loudspeaker systems, the company is not only able to present classic stereo solutions, but also a very wide range of systems for home cinema. The “good sound” for television is therefore an essential area for the company from Schwäbisch Gmünd, so that the product group that many users use here, namely the so-called sound bar or sound desk systems, cannot be ignored.

Nubert electronic GmbH can already show many a fine product in the area of soundbar and sound desk solutions, whereby it seems particularly exciting that they follow a somewhat different concept than many other manufacturers in this segment. The solutions from Nubert electronic GmbH clearly show that a loudspeaker specialist with the appropriate expertise is at work here, so the solutions are more similar to conventional loudspeaker systems, and this leads to a significantly better sound for television broadcasts, films, games, but also music. This strategy is also being pursued in Schwäbisch Gmünd with the latest solution, the Nubert nuPro AS-3500, a TV sound system that once again offers full performance, a classic three-way system, and for the first time also native processing of Dolby Digital and DTS Digital Surround.

Conventional sound-bar systems, especially those made by TV manufacturers, who like to advertise them as the optimal solution for their TV sets, are designed to be as slim as possible. Nubert electronic GmbH, too, speaks of a slim design for its latest soundbar, the Nubert nuPro AS-3500, with dimensions of 90 cm in width, 14.3 cm in height, and especially 33 cm in depth, but it is still considerably larger than many other models, so that it is actually more of a sound desk than a soundbar. And with good reason! A rich sound requires the appropriate volume, as well as solid workmanship, which is of the same high quality as that of regular loudspeaker systems from Nubert electronic GmbH.

The basic construction is also much more similar to a conventional loudspeaker system than other solutions, as the new Nubert nuPro AS-3500 is an active three-way bass reflex system.

Two 169 mm long-throw woofers equipped with polypropylene membranes are used initially. These can be found on the underside of the Nubert nuPro AS-3500, so they actually act like downfiring subwoofers. These are also combined with two low-midrange drivers, whose polypropylene membranes each have a diameter of 119 mm. Two 25 mm silk fabric domes are responsible for the upper frequency range. The bass reflex system of the new Nubert nuPro AS-3500 is led out to the rear. Accordingly, there are four adjustable spikes on the underside, which guarantee a defined distance to the floor space.

As already mentioned, the new Nubert nuPro AS-3500 is based on a solid construction, specifically an MDF cabinet, which is finished in matt black or matt white with sanding varnish. A clear indication of how solid the case has been realised is the weight of the new Nubert nuPro AS-3500, which is 20.3 kg.

The corners of the Nubert nuPro AS-3500 are elegantly rounded, and of course a matching loudspeaker grill is included, which is held in position by magnets.

The chassis of the new Nubert nuPro AS-3500 are driven by a Class D amplifier system, which delivers a whopping 240 watts of continuous power or 340 watts of music power. On closer inspection, the data sheet reveals that there are four Class D amplifier modules, each delivering 60 watts. Also impressive is the frequency range that the new Nubert nuPro AS-3500 can cover, which is specified as 36 Hz up to 22 kHz.

Nubert electronic GmbH states that the new Nubert nuPro AS-3500 offers transparent highs, powerful mids and driving basses and guarantees a room-filling sound. It is essential that the user himself can intervene in the sound image according to his individual ideas, for example to increase the bass performance, to optimise it with a loudness function at low levels or to reduce it at late hours.

The so called “Hörizont-extension”, which Nubert electronic GmbH already used in the smaller Nubert nuBox AS-225 and the top model Nubert nuPro XS-7500, and which can also be found in the new Nubert nuPro AS-3500, is probably the most ingenious addition. If desired, the user can use it to expand the sound stage with a special circuit to optimise the stereo image. This is intended to overcome the problem that can result from a very close arrangement of the drivers for the left and right channels, namely the missing reproduction of the said stereo width. This should not only benefit films, but also the sound quality of music in particular.

What is new is that the Nubert nuPro AS-3500 now has a so-called Voice+ function. This is intended to optimise speech intelligibility, as it allows dialogues to emerge more clearly from soundscapes and music. Nubert electronic GmbH states that this function, especially with the Loudness function, is ideal for reproduction at low levels.

Another new feature, we have already briefly mentioned, is that the Nubert nuPro AS-3500 can now process content in Dolby Digital and DTS Digital Surround, whereby playback is optimised for stereo. Nubert electronic GmbH does not operate virtual surround games here either.

The connection to the TV set is, of course, via HDMI, whereby this interface supports not only an ARC (Audio Return Channel) or eARC (enhanced Audio Return Channel), but also HDMI CEC, so that central control is possible with the remote control of the TV set alone. However, Nubert electronic GmbH also supplies a suitable remote control with the new Nubert nuPro AS-3500, this should be mentioned in passing. In addition, all essential operating steps can also be carried out directly on the device itself; a centrally located rotary encoder on the front including status LEDs makes this possible.

Back to the connection options, the new Nubert nuPro AS-3500 is not limited to HDMI alone, but also offers digital and analogue audio interfaces as an alternative or in addition to this, in order to be able to integrate further sources. In addition to an optical and coaxial S/PDIF interface, a stereo RCA input is also available. The new Nubert nuPro AS-3500 is also equipped with Bluetooth, whereby Bluetooth 5.0 is used and aptX, aptX LL and aptX HD are supported in addition to SBC and AAC.

Nubert electronic GmbH expressly points out that the new Nubert nuPro AS-3500 does not support the high-resolution wireless radio transmission Nubert X-Connect in order to network it with the models of the Nubert nuPro X series. However, the company does offer the optional Nubert nuConnect trX transceiver as an extension option, via which this is in turn possible, including the subwoofers of the Nubert nuSub series. Conventional subwoofers can be connected via cable, but of course directly via a corresponding output if there is a need for even more bass.

According to the manufacturer, the new Nubert nuPro AS-3500 is expected to be available from February 2021, but this solution can already be pre-ordered now. Until 31 December 2020 Nubert electronic GmbH will grant a special introductory price of € 895,- to quickly determined customers, after that the price should be € 965,-.

As already mentioned, the new Nubert nuPro AS-3500 offers a choice of matt white or matt black, and both versions of the loudspeaker grill are in anthracite. In addition to the remote control, the front cover and a power cable, the scope of delivery also includes an HDMI cable, an optical digital cable, a stereo mini jack to RCA cable and height-adjustable spikes.
