This year DNH will celebrate 80 years of being at the cutting edge of industrial and commercial loudspeaker technology. From our small factory in the picturesque town of Kragero in Norway we have developed into a world recognised and respected brand, with offices and warehouses around the world.
In our 80 year history we have been responsible for many "firsts" in loudspeaker research and development.
The worlds first fully certified loudspeaker for use in hazardous area's, and later the first plastic loudspeaker for the same environment.
The much emulated full frequency range Music Horn was a DNH product.
A fully encapsulated underwater loudspeaker for music reproduction that has now been modified and adapted to become the first, fully certified, clean room loudspeaker for use in class 1 clean rooms.
But we don't let up
Now DNH is developing a range of products to comply with the very latest Marine Equipment Directive, you can view a range of these units and our EN-54 approved units at the Fire Safety Event
