The 8381A empowers engineers and creators to perceive every sonic detail, offering true-to-life sound level and dynamics – with the full flexibility of free-standing monitor placement and advanced room adaption.

Tailored precisely to your room

Interacting with our Genelec Loudspeaker Manager (GLM) software, the 8381A monitor system intelligently adapts its response to the monitoring room in the optimal way. This offers great flexibility to tackle even the most challenging environments – delivering precise presentation, including low frequency reproduction that integrates perfectly with the complete sound content.

The 8381A has been engineered to deliver the complete audible content, with a response extending to frequencies beyond the standard audible range – and fully aligned in the time domain – it delivers precise understanding of all the minute details in recorded waveforms. With its high SPL capacity, the 8381A is able to make even very low-level details audible, making it an uncompromising tool for monitoring.


Imaging you can trust

Quickly arrive at the right mixing and mastering decisions through uncompromising imaging detail. The point source operating principle of the 8381A offers the unique advantage of maintaining precise sound colour and imaging at all listening distances, enabling exceptional freedom of placement, and removing the vertical sound colour change typical of larger monitors.

The carefully designed Directivity Control Waveguide ensures clean off-axis sound colour, reducing the impact of the reverberant sound in the monitoring room on mixing decisions, while improving the accuracy and reliability of monitoring work in all rooms.

Standing on the floor, the 8381 locates the soundstage at the natural listening height, while supporting traditional high main monitor positions with the included incliner system. This enables the acoustic axis to be optimally configured towards the listening position for all installation heights.

A liberating new solution

The innovations of the 8381A push the limits of free-standing monitoring solutions, creating a powerhouse that deeply envelops the listener in flawless, true-to-life sound images.
The monitor excels at revealing the finest details of audio by combining immense, controlled power with pinpoint imaging precision, even in challenging monitoring spaces.

The point source design principle combined with optimised directivity control maintains the frequency balance in off-axis positions, supporting correct understanding of the sound colour when moving, standing or sitting in the monitoring room.

Genelec quality and support

Crafted with expert guidance from celebrated Industrial Designer Harri Koskinen, the 8381A is completely designed and built in Iisalmi, Finland. Drawing on more than four decades of company experience, Genelec’s passionate engineering team meticulously designed and optimised every component of the 8381A. In doing so, we’ve created a monitoring loudspeaker that’s ideal for the audio world’s most demanding applications – built to perform with effortless power and zero sonic compromise.

The 8381A powers a lifetime of creativity, so it comes included with access to our unique Genelec SonicAdvisor™ services. So, if you require any support on your monitoring journey with the 8381A – from initial configuration to on-site consultation – we’re ready to help.
