The great advantages of our products

Configuration Options & Available Heights

DEMVOX ™ soundproof booths are modular, so in addition to being able to create an infinite number of available sizes, there is the possibility of configuring each piece in the position that best suits your needs.
In this way, the door, window, cable glands, ventilation, etc. can be placed in any available position.

Of course, you can also add more windows, choose the opening side of the door, place windows on the roofs, or use panoramic windows. On the DV model, it is also possible to choose higher heights in 228mm steps (and a low -228mm height).

Durability, Maintenance & After-sales

Thanks to the quality of the materials we use in our cabins and the acoustic felt finish, the product has an extremely long service life. The felt finish provides unique acoustics both inside and outside, as well as providing protection against bumps and scratches when handling, moving, transporting and installing each module.

Great durability over time: the product remains in optimal condition over the years.
Low maintenance costs: our cabins have practically no maintenance costs.
Retrofitting: the booths adapt perfectly to new projects, extensions or reductions in sizes to adapt to a new space, change in height, etc.
Post-sale: taking into account the above points, one of the great advantages we obtain is the great ability to recover the initial investment if a project is completed and the products need to be sold. When planning a project, this option to recover the capital invested in cabins is very important, and in our cabins it can be around 80-85%. DEMVOX also offers disassembly, transport and installation for all customers who need to move or expand their cabin. Also in second-hand sales. 

Expandable & Reducible, Forever

Our cabins can be expanded at any time, achieving a larger space and adapted to the needs of each moment.

It is also possible to add any extra element: extra windows, additional cable glands, doors, panoramic windows, special platforms, shelves, acoustic panels, bass traps, etc.

In DV models it is also possible to modify the total height, making the cabin lower, or higher in 228mm sections.

Of course, it is also possible to reduce the size, or even obtain several small cabins of a larger cabin (by adding the necessary panels such as the door and ventilation). DEMVOX offers each item for sale separately to meet the demand of any project.

Technical Service & Transportation

We offer customers the most practical and safe option for transportation and installation of the purchased product. Because some sound booth models have a precise fastening system, the DEMVOX™ Technical Service will be responsible for conducting this process only for the initial installation, by ensuring proper leveling of the ground and optimizing the fitting of all parts and panels.

We send our cabins to practically all countries in the world by land and sea, and we also go to the facility if the client requires it.

Technical Service and Transportation Service

Portability & Installation by Own Customer

All our models are easy to transport, install and uninstall as many times as necessary and in the place that is necessary for each project. (We recommend that the first installation of the DV model be carried out by our technical service, or through online advice.) 

With our patented fastening system by means of screws and metal bushings, the modules can be installed safely, guaranteeing the ideal pressure to prevent leaks or areas where sound can flow. Each layer is attached independently of the other, and the whole set of different layers are coupled in the structure through silentblocks and insulating materials, which allows an ideal operation to combat medium and severe frequencies.

The clamping system also provides our soundproof booths with a solidity and robustness unique in the market. 

DEMVOX 5 Year Warranty
