Liveliness and musicality.
Lets dreams become reality.


The name of this high-end loudspeaker already expresses what one can expect in terms of sound: liveliness, musicality and absolute tonal balance.

With a height of only 100 cm, the ESPRIT also looks discreet in smaller rooms. In doing so, it impresses with its elegant and aesthetic proportions and gives the room an exclusive touch as a high-quality piece of furniture. The loudspeaker chassis are covered by a matt powder-coated metal cover.

Hidden behind the metal cover there is a 10“ bass, 6“ midrange, 5“ dome midrange and a 1“ dome tweeter, making it a fully active 4-way system. Together with the LOG AudioEngine and 4 Class A / B power amplifiers, these speaker chassis make the ESPRIT a reference loudspeaker with an incredibly well-balanced tonal expression and impressive bass performance.

The high-quality sound speaks for itself and makes the ESPRIT probably the most convincing loudspeaker of its size.

10" Bass

The 10" bass speaker ensures a rich and dry bass reproduction and provides a solid sonic foundation.

6" Midrange/Bass  Speaker

The 6 "midrange is perfectly integrated between the dome tweeter and the 3" midrange speaker and ensures a clear reproduction of the upper mids.

1" Dome Tweeter

The textile dome tweeter ensures crystal clear and transparent trebles up to a frequency range of around 10 kHz.

3" Dome Midrange Speaker 

Especially for the very crucial low mids, this dome midrange speaker convinces with powerful mids and a crystal clear reproduction of voices and instruments.


The new ESPRIT is the next alternative to the larger models VIVANT and VERVE and provides absolutely outstanding sound performance, especially in smaller listening rooms.


The minimalistic yet elegant shape of the ESPRIT is a masterpiece of sleek design. With a total hight of only 100 cm and the symmetric, slightly curved shape, this model is a prime example of a functional design approach. The handmade wood-based cabinet  is available with either a striking black high-gloss piano lacquer finish or a matt-black lacquer.

The 4-way speaker setup is covered by a magnetic, sound permeable metal plate and can easily be detached from the cabinet to show the avid listeners the speaker-chassis that are hidden behind the cover. To avoid resonance and guarantee a solid stand, the speaker has 4 adjustable spikes, while the rear of the speaker has a digital input and a digital output.

The ESPRIT convinces with its well-conceived design and enriches every room with an elegant and luxurious appearance. 

PROLOG select

In combination with a PROLOG control unit, the ESPRIT offers full connectivity and additional features such as room correction and lossless signal transmission.

Digital & Analog XLR Inputs

The ESPRIT offers digital and analog inputs for maximum sound reproduction quality in every setup. For the best possible sound quality, the digital input is used with a PROLOG control unit. The digital audio signal is then transferred to the speakers losslessy, either via XLR-cable or 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 ESPRIT 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.

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.

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.
