DEMVOX: manufacturers of professional soundproof booths since 2009

Since 2009 we are a pioneer in the field of modular soundproof booths, developing our own solutions to meet the real needs of musicians, recording studios, speakers, companies, schools, offices, voice professionals and users who need to control the sound effectively.
Unlike generic solutions or standard acoustic cabins, DEMVOX is a manufacturer. We design, develop and evolve our own product families, with modular systems designed to offer acoustic insulation, flexibility, durability and adaptation to different spaces.
In-house manufacturing and patented assembly system
One of the great differential elements of DEMVOX is its own assembly system, unique and patented worldwide. This system has been developed by our company to improve modularity, assembly precision, structural strength and adaptability of our soundproof booths.
Thanks to this patented system, DEMVOX cabins can be assembled, disassembled, extended, modified or relocated with a flexibility far superior to that of a traditional fixed construction site, while maintaining a solid, professional structure ready for intensive use.
This way of understanding modular acoustic insulation allows us to offer more versatile solutions, adaptable and adjusted to the real needs of each client.


Soundproofed cabins of European manufacture, for the whole world
DEMVOX is a European brand specialized in professional soundproof booths. For those looking for soundproof booths in Spain, European manufacturers of soundproof booths or professional modular sound insulation solutions, DEMVOX offers a solid alternative based on experience, own manufacturing and technical development.
Our booths are not impersonal products or imported solutions without specialization. They are our own systems, developed in Madrid, Spain for years and designed for different levels of acoustic requirements, from everyday voice and recording to high demand professional applications.
We ship our products all over the world, and we come to install them in the projects required by the customer.
DV: the most complete, versatile and adaptable system from DEMVOX
Within our range, the DV system represents the most complete, versatile and adaptable solution from DEMVOX. It is a high performance professional soundproof booth, designed for the most demanding uses and with unique insulation capabilities within the modular soundproof booth market.
The DV range allows multiple configurations of size, access, doors, windows, ventilation, finishes and interior layout. This adaptability makes it a particularly suitable option for recording studios, rehearsal rooms, acoustic drums, percussion, amplified instruments, music production, audiovisual environments, educational centers, companies and technical facilities.
DV is not a standard booth. It is a professional modular system developed by DEMVOX to offer insulation, customization, durability and flexibility in projects where acoustic control is a fundamental part.
Solutions for music, voice, recording, office and industrial applications
Throughout our history, we have developed different families of booths to meet very different uses and needs. DEMVOX offers solutions for singing, playing instruments, recording vocals, voiceovers, producing audiovisual content, teaching, video calls, creating privacy spaces, technical testing or developing customized acoustic projects.
Our booths are used in homes, recording studios, music schools, conservatories, offices, companies, educational centers, rehearsal rooms, production companies, clinics, laboratories, industrial spaces and other environments where it is necessary to reduce sound transmission and improve acoustic control.
This experience allows us to understand that not all booths must fulfill the same function. A booth for voiceover does not have the same needs as a booth for acoustic drums, a meeting room, an office booth or a technical space for sound tests.
Professional soundproof booths, not just acoustic booths
Not all acoustic booths are the same. There are solutions designed exclusively for privacy, call or interior reverberation reduction, but a professional soundproof booth must be designed to reduce sound transmission to the outside.
In DEMVOX we clearly differentiate between office privacy booths, basic acoustic booths and professional soundproof booths. Our work is focused on offering modular acoustic insulation solutions adapted to the actual use of each client.
Technical advice before choosing a booth
Buying a soundproof booth should not be a decision based only on a measurement or an image. The result depends on the intended use, the type of sound, the volume, the environment, the neighbors, the location, the access and the characteristics of the space where it will be installed.
For this reason, at DEMVOX we give importance to the previous advice. We evaluate each case to guide the customer towards the most suitable product family, avoiding oversized or insufficient solutions and helping to choose a cabin really adapted to their needs.
A brand with a track record, real customers and constant evolution
Since 2009, DEMVOX has worked with individuals, musicians, producers, broadcasters, studios, companies, educational centers, offices and professionals from different sectors. This trajectory has allowed us to accumulate real experience in very different installations, uses, acoustic needs and configurations.
Our cabins have evolved over the years thanks to our own technical development, experience in real projects and the continuous improvement of our systems. Each new DEMVOX solution is born from a clear idea: to offer professional soundproof booths, modular, reliable and adapted to real spaces.
