Sound by design express our deeply rooted focus on innovation, latest technologies, Danish design and our tradition of collaborative craftsmanship. Our goal is unparalleled appeal to the auditory, visceral, and visual senses.
Founded in Denmark by Ole Siig, 2022
Passion for Science and Music
Authentic Reproduction of Music
Careful consideration goes into every detail of Treble Clef Audio® loudspeakers. Form follows function is not just a design concept to us, it is foundational to the authentic sound and visuals aesthetics that blends into thoughtfully curated interiors.
Our patented no-box Air Velocity Transducer Bass System, state-of-the-art Digital Signal Processing (DSP) and amplifier technologies are consciously applied with a clear goal: To authentically reproduce music and ambience experiences with the true character of bass - like never before.
Taught by His Musical Family
Growing up, Ole Siig was influenced by his creative and musical father Helge Siig, who developed X-Ray equipment used for quality assurance of airplane wings. His father instilled him to his passion for functionalism, design and attention to detail. During the late 1950s and into the 60s, as a hobby, Helge created unique furniture that integrated form and function.
Helge was also an accomplished musician. Hence, the interest in music, audio, design and science all came naturally. Being fortunate to having raised children with musical talent, Ole's home has been filled with the inspirational and initially scratchy sounds on the violin and fumbling fingers on the piano, later developing into fully accomplished and enjoyable performances that tuned his ears to how instruments really sound.
Tuned His Ears to How Music Really Sounds
In his teens, Ole built several box type loudspeakers, an active analog phase-linear crossover and other audio electronics, all as a passion. During high school he worked the evening shift at the Peerless loudspeaker factory in Denmark, responsible for mixing diaphragm paper pulp and managing the machine stamping out and heat forming the center spider for a series of woofers.
Ole's career, until now, went from electrical engineering and computer science to designing and product managing software solutions for the shipping, financial, commodities, energy and law sectors. This experience has equipped him with deep research, technical skills and familiarity with the product life-cycle process. About six years from idea to research and development lead to a fundamentally new patented loudspeaker concept and the launch Treble Clef Audio®.
Behind the Science
Large box loudspeakers have had their time in the limelight, conventional and relatively easy and inexpensive to manufacture, but no matter the materials used, far from ideal. For good reason no acoustical instruments, perhaps with exception of the Cajón, is shaped as a box seeking to contain half of the generated sound.
Our foundation is an understanding of the complex relationships that makes the difference between a pretty good sounding loudspeaker versus our goal of one perceived so authentic that you are always looking forward to more great experiences immersed in the art of music.

Scientific Innovation
Driven by pioneering patented technology and state of the art engineering, Treble Clef Audio® pushes the boundaries of HiFi performance.
The challenge to revive original sound within the constraints of a home demands intense scientific investigation and functional design. Despite a well-established science of acoustics, modern innovation has yet to evolve from ordinary box design loudspeakers associated with inherent bass limitations, optimal sound only in a sweet spot and pronounced room interaction.
Our loudspeakers uniquely maintain the detail and clarity of deep tones, employing our patented vibration eliminating, resonance free, omnidirectional asymmetric dispersion air velocity transducer bass system. The mid-range and tweeter are elevated to ear height, featuring slender shapes and curves to minimise sound wave diffraction. Our design ensures a wide and uniform pattern of sound dispersion, providing both accurate and even tone distribution in and outside the room.
Continuing the Danish Modern legacy, functionalism is a core principle of Treble Clef Audio® design aesthetics. Every component of the Model TCA-M loudspeaker is thorough and meaningful. It is nothing short of a sculpture formed to support acoustic function at every bend.
Built-in modern Digital Signal Processing (DSP) and Amplifier technology ensures optimal consistent performance that adapts to either analogue or digital audio input.
Utilising state-of-the-art audio measurement methods and with the ears and experience of music lovers, Treble Clef Audio® integrates objective science with imaginative innovation and a visual signature that blends effortlessly into home interiors.
Treble Clef Audio® loudspeakers brings you closer to musical performances than ever before.
Traditional Craftsmanship
For Treble Clef Audio®, details are not just a detail. From details the function and design emerge forming unparalleled sound experiences.
Fusing the appeal of Danish Modern design with the philosophy of form-follows-function, we take care to select the finest materials. Our design proudly exposes engineering detail and functionality.
A close relationship between our carefully selected suppliers, partners, and specialists secures the highest production and performance standards.
With the made to order approach, Treble Clef Audio® loudspeakers are carefully hand assembled with the utmost passion and dedication to details, fine-tuned for lasting performance and delivered in sustainable return to base custom flight cases.
Our engineering approach ensures the flexibility to care for and upgrade each customer’s unique models. Because sustainable design, foresight and craftsmanship is essential to us.
Danish Design
Treble Clef Audio® is deeply rooted in the Danish Modern tradition of applied science, function and form. The distinctive design is far from conventional, but grounded in our slogan, Sound by Design™.
By reimagining acoustic principles and technical design with precision engineering, the TCA-M loudspeaker incomparably captures both the character of instruments and the ambience of musical performances from the deepest bass to the highest pitch.
Free of flat surfaces and edges, the TCA-M is not only a translation of objective acoustic science, but equally creating a lasting legacy that combines authentic sound reproduction with timeless design aesthetics.
“To this day, I have fond memories of the desk and chair my father made for me; I spent most of my time with Lego builds and finishing homework here. Eventually, my legs outgrew the desk, but its functional beauty has not been lost.”
