With Dolby Encoding, a sound balance and Voice+, it offers a significant upgrade to the nuBox AS-225.

Your TV has never sounded so good

As a powerful upgrade for the TV, the nuBoxx AS-225 max provides a powerful, well-founded, lively sound for all signals that the TV transmits via HDMI-eARC - including Dolby Digital. With HDMI-eARC, you can conveniently control the volume using the TV remote control. The Voice+ function also makes all dialog clear in every situation.

nuBoxx AS-225 max Stereo

The musician

The nuBoxx AS-225 max is also suitable for acoustically clear, dynamic music reproduction in classic stereo - something you wouldn't expect from such a concept. Your favorite tracks can be played via an existing CD or network player via the digital inputs, or streamed from a smartphone via Bluetooth including aptX.

The nuSub is already waiting

That's impressive: 36 Hz lower cut-off frequency means a lot of depth and bass. But true fans of action-packed spectacles often want even more low-frequency power. Our nuSub portfolio is ready for these users - for example with the compact nuSub XW-700.

Perfect PC partner

A nuBoxx AS-225 max can also be used on a PC as a platform for the screen and at the same time significantly improve the acoustics. You can use the optical or coaxial input to bring lossless digital game audio tracks and music to the soundbar. Alternatively, the signal can be fed in analog via the RCA inputs.

With Dolby Digital decoder

Many films on Blu-ray or DVD as well as content from numerous streaming services usually come with a Dolby Digital track. By integrating the appropriate decoder, we can realize optimal sound from the data stream. Together with the other high-quality features of the nuBoxx AS-225 max, this results in a realistic, captivating sound image.

Technical information

Box type, sound and recommended use

Modern flat-screen TVs draw high-contrast, colorful pictures with ultra-high resolution and buttery-smooth movements. However, the thin housings offer too little space for potent speaker drivers, which is why the sound usually cannot keep up with the display quality. Nubert soundbars provide a remedy: The nuBoxx AS-225 max is the compact sound upgrade for your TV.

The nuBoxx AS-225 max upgrades the acoustics in your living room in no time, provides more TV fun and - thanks to the integrated Bluetooth receiver - music enjoyment in great quality. Setup and connection are done in a few minutes: With many TV models, the flat soundbase can be placed directly under the stand, where it also functions as an attractive pedestal. But the soundplate also cuts a great figure in a lowboard compartment or simply in front of the TV, especially since its clean, angular lines and black or white finish perfectly match many interior styles and furniture.

The easiest way to connect the nuBoxx AS-225 max to your TV is via HDMI cable. The soundbar is connected to an ARC or, even better, eARC-capable input, which also transmits control commands in addition to the sound signals. For example, the volume of the sound system can be adjusted with the TV remote control.

Despite the compact dimensions and attractive price point, the nuBoxx AS-225 max appears amazingly grown-up: with room-filling voice, powerful bass and authentic effect reproduction. For movies and TV shows, you won't want to miss the virtual stage extension (wide effect) and speech enhancement (Voice+). The former provides a wider, more vivid sound panorama that immerses viewers directly in the action. Voice+, on the other hand, puts the spoken word more in the acoustic focus and guarantees clear comments and better understandable dialogs. Thanks to the integrated Dolby decoder, the Soundplate optimally prepares movies and series streams in every situation.

Because the nuBoxx AS-225 max carries true "hi-fi genes" and relies on the same proven driver and amplifier technology as Nubert's compact active speakers, it shines not only with movie and TV sound, but also with music playback. Using a cell phone or tablet as a wireless Bluetooth player, you can easily enjoy your favorite songs, listen to radio streams or podcasts. Acoustically, the nuBoxx AS-225 max can easily compete with a compact stereo system and even has advanced sound settings for bass and mids/treble as well as a loudness function for powerful low-frequency reproduction at low volumes.

Thus, the nuBoxx AS-225 max is ideal for anyone looking for a compact and affordable, but high-quality sound upgrade for the TV at home.

Design principle and housing

As a fully active two-way soundbar, the nuBoxx AS-225 max uses an active crossover and a total of four powerful digital amplifiers with 45 watts of music power each, one for each of the four loudspeaker chassis and frequency paths. The digital operating principle enables precise separation and equalization of the frequency ranges, which accounts for the good low-frequency performance of the comparatively compact soundbar.

The speaker cabinet is made of 19 millimeter thick medium-density fiberboard (MDF), which reliably reduces resonances and promotes a clean sound image. Thanks to the stable construction, the nuBoxx AS-225 max supports TV sets weighing up to 40 kilograms. The two bass reflex ports are located on the back of the system.

The cabinet body is equipped with a high-quality decorative foil in white or black, the baffle is satin lacquered. The removable, magnetically adhering front cover is covered with optimally permeable acoustic fabric.

Chassis

The nuBoxx AS-225 max uses two 118-millimeter woofers and two 25-millimeter tweeters, both of which were specially developed for the nuBoxx A series speakers and have impressive performance values for their size class. For example, the soundboard owes its impressive lower cutoff frequency of 36 Hertz (at -3 decibels) to both the precise DSP control and the tuned long-throw woofers. The textile dome tweeters are characterized by excellent omnidirectional sound distribution and particularly fine resolution.

Operation and setting options

When connected to an ARC- or eARC-enabled HDMI port, basic functions such as volume and standby can also be accessed via the TV. The included remote control, which is characterized by its high-quality feel and elegant design, allows quick access to the various sound settings of the soundbase.

Multicolored LEDs around the rotary knob provide clear information about the selected input and the device's status, and are also easy to see through the removable fabric cover.

Tone control

The nuBoxx AS-225 max is neutrally tuned and outputs true-to-original two-channel sound at the factory. In addition, during the sound tuning, emphasis was placed on the best possible speech intelligibility and a wide sweet spot. If an even more effective reproduction is desired, pressing the Wide button on the remote control activates a special DSP circuit, which increases the spatiality of the reproduction and makes the sound events seem more three-dimensional - ideal for movies and TV shows. The effect expands the acoustic stage and immerses the listener even deeper into the sound experience. We call this "listening zone expansion".

The "Voice+" function, which emphasizes the center channel and the frequencies relevant for voice reproduction, proves particularly useful for movies and TV shows. This increases speech intelligibility in suboptimally mixed broadcasts and during quiet playback.

Connections

The soundbar features five audio inputs and one output. There is an optical digital and an electrical digital connection, an HDMI-eARC port, an analog stereo RCA connection and a Bluetooth receiver for wireless connections. Thus, users enjoy almost free choice when it comes to the feed player: Almost all modern media systems can be connected, from classic CD players to multimedia computers, game consoles and TVs, and even mobile multi-talents such as smartphones or tablets.

A sub output is available for connecting an external subwoofer. If this is used, the lower cut-off frequency of the nuBoxx AS-225 max is raised to 80 Hertz, which increases the level reserves.

Energy

The nuBoxx AS-225 max is equipped with a convenient automatic energy-saving feature, which switches the speakers on independently or puts them into power-saving standby mode when not in use. In this stand-by mode, which can also be activated manually via the remote control, the speakers consume less than 0.5 watts. The wide-range power supply allows this soundbar to be used on mains voltages from 110/120 to 230/240 volts.
