8381A Master Edition
Discover every detail of sound

Relax, entertain and feel
Meet The Ones
When ideal sound from loudspeakers and wall reflections arrives coherently at our ears, no matter where we are in the room, we are touched by the full emotional impact and healing powers of audio. Genelec The Ones are all built to deliver this experience, with the 8381A 'The Main Ones' model standing at the pinnacle.

Your home at its best
With sound like the artist intended
Depending on positioning within the room, the sound of uncalibrated loudspeakers changes. With the 8381A, automatic calibration is included, so the loudspeaker system adapts with ease to sound neutral in your room – allowing you to freely choose the position. The calibrated sound can be set according to professional music studio standards, cinema standards, or simply to your personal taste. The choice is yours, and presets can be easily stored and switched.

Built on passion and innovation
The apex of Genelec design and technology
The five-way, full-range 8381A incorporates advanced, high SPL evolutions of our phase-coherent, point source MDC™ Driver and Adaptive Woofer System – proprietary technologies that have revolutionised the world of audio forever. Born of the expertise we've gained over more than 45 years as the world's leading manufacturer of studio monitors, this pioneering high-end solution represents the very finest in Genelec engineering.

Dressed to impress
A shining beacon of excellence
Celebrated Finnish Industrial Designer Harri Koskinen has once again collaborated with Genelec to ensure that while every element of the 8381A Master Edition is crafted for absolute acoustical excellence and premium quality, the loudspeaker also looks the part.

Assured sustainability
Genelec's award-winning approach
At Genelec, sustainability and repairability are at the heart of everything we do. At our lakeside factory in the idyllic town of Iisalmi, Finland, we work tirelessly to reduce our carbon footprint, recycle waste, and use renewable energy and materials, following the highest environmental, social and industrial standards.
Like all our loudspeakers, the 8381A is lovingly built to last a lifetime and optimised to minimise consumption wherever possible, making it a truly gratifying investment – capable of igniting your audio passion for decades to come.
