Breaking traditions.

Making a statement.

Now full wireless connectivity with
the optional control model


The CUBE is a technical masterpiece designed specifically for ultimate high-end requirements of discerning audio enthusiasts.

Ultra-fine trebles, crystal clear mids and a powerful, dry bass response come from a 3-way speaker combination that has proven itself as top-of-the-line solution for many years. The 1" dome tweeter, the 6.5" bass-midrange speaker and the 6.5" subwoofer combine ultra-low distortion, maximum dynamics and an unprecedented level of supreme musicality. The convincing performance from a speaker of this size is simply sensational.

The design goal was to create something drastically different, but in a way that is feels familiar to everybody. Something that no one would expect from a high-end speaker, but one that is so appealing that it creates instant attraction. CUBE is designed for modern lifestyle individuals who enjoy maximum musical performance but do not insist on the classic "speaker look".

The result is a simple and timeless, yet elegant and luxurious piece of design that can be perfectly integrated into any living space without taking up a lot of space.

The CUBE impresses both in sound and in design, regardless of whether it is used as a stereo system for breathtaking music playback or as a component in a 5.1 or 7.1 home theater system.

6.5" Bass/Midrange

Especially in the middle and vocal range, this bass midrange driver performs with outstanding  assertiveness and clarity. 

1" Dome Tweeter

The fabric dome tweeter brings crystal clear trebles and an unparalleled feeling of lightness in the higher frequency range.

6.5" Subwoofer

For rich bass in the very low frequencies, the bass/midrange speaker is supported by 6.5" subwoofer and impresses with a tremendous precision.


The CUBE impresses with its simple and elegant shape, which fits perfectly into every living room. Despite the small edge length of approx. 30 cm, this 3-way system with a built-in subwoofer brings the ultimate high-end experience into every home without taking up a lot of space.

The CUBE is available in all RAL colors and also in a black piano lacquer finish. For the magnetic front cover, you can choose between silver (stainless steel), anodised black or an even more exclusive hand-made gold version. With the optional stainless steel stand, this high-quality high-end loudspeaker is ideally presented in your elegant living room.

The back of the speaker – a black anodised metal plate – gives room for digital and analog inputs, the power switch and a DIP switch for different adjustment settings.

With the optional WiSA wireless audio signal transmission, you will only need on cable to power this active speaker. No audio cables are required, which guarantees maximum flexibility and – of course – a great, cable-free and independent look – and yes: the power-cable can be hidden inside the stainless steel stand.

Digital & Analog XLR Inputs

The CUBE offers digital inputs for maximum sound reproduction quality in every setup. To ensure maximum sound quality, the digital input is used with a CUBE+ or a PROLOG control unit. The digital audio signal is then transferred to the speakers losslessly, either via XLR-cable or WiSA wireless technology.


The CUBE+ is the exact same speaker as the regular CUBE but with integrated connectivity features such as two TOSLINK inputs, Wifi & Bluetooth

PROLOG select

If not used with a CUBE+, the CUBE can be upgraded to full connectivity and additional features such as room correction and lossless signal transmission using the PROLOG. The PROLOG then serves as digital control unit for two regular CUBE models.

Digital & Analog Inputs

The PROLOG offers digital and analog inputs for maximum sound reproduction quality in every setup. For the best possible sound quality, the digital input is used, either via the optical TOSLINK input or via Wifi/LAN. The digital audio signal is then transferred to the speakers losslessy via digital XLR-cable or using WiSA wireless technology.

Bluetooth aptX

Bluetooth aptX is the easiest and fastest way to connect your smartphone and stream music in high quality.

AirPlay & DLNA

For full wireless connectivity, both AirPlay and DLNA are supported by the PROLOG. Music can also be easily streamed to your CUBE using the various integrated services, such as Spotify Connect, Tidal, Deezer or TuneIn Radio.

Wireless Signal Transmission

It is now also possible to losslessly stream music from the PROLOG control unit to LOG speakers using WiSA wireless signal transmission. This means that there is no need for a digital XLR-cable, making it even more comfortable to install and to use. With 24bits at 48kHz/96kHz, it's also twice the quality of CD audio at almost no latency.

PROLOG phono
Digital Phono Stage

With the new digital phono stage from LOG Audio, you can now combine the best of two worlds – analog and digital. The extraordinary sound quality of vinyl LPs is transferred perfectly into the digital environment of the PROLOG, using digital RIAA equalisation and linear-phase FIR-filters.


With DIP-switches on the back of the speaker, you can easily mute the analog input, define the speaker as left or right (when using the digital input), adjust bass and treble frequencies and change the input level of the analog input.

DIP-switch settings
Linear-phase, digital room correction

With the high-performance DSP of the LOG AudioEngine, room correction is achieved without losses or phase-shifts. All adjustments can be done inside the PROLOG control unit without touching the speaker physically.
