Intro (Our Philosophy)
Bring clarity to an industry
DEM Audio was created to bring clarity to an industry full of smoke and mirrors. With a foundation in signal processing and acoustics, the company focuses on what the waveform actually says rather than following trends. Central to our work are custom loudspeakers, designed to perform precisely in each listener’s space.
Our Technology
At the core of DEM Audio’s approach is LinFIR, a proprietary software developed to design linear-phase FIR filters with surgical control over phase and magnitude. This same technology is applied to every crossover, correction curve, and time alignment in our custom loudspeakers. By combining advanced DSP with careful cabinet design, each system is tuned for accuracy and musical fidelity.
Tailored for Musicians and Listeners
Each custom loudspeaker is engineered for its intended environment, whether a professional studio or a private listening space. Our goal is to make the speakers disappear so that only the music remains. Every project is handled with precision, from conception to delivery, for musicians, producers, and passionate listeners who demand clarity, consistency, and detail.
Why Choose DEM Audio?
We believe that great audio comes from rigorous engineering, not marketing hype. Every DEM Audio system is designed with the same principles: precision, transparency, and fidelity to the original waveform. From software-driven filter design to the final room tuning, we aim to provide sound that truly reflects the artist’s intent.
We also build the speakers
But DEM Audio is not just about filters—every loudspeaker system is fully custom, engineered from scratch to match the client’s space, listening habits, and aesthetic preferences. No generic cabinets, no factory voicing—just pure, purpose-driven sound.
