DNH loudspeakers
TTTBV has been an importer for the leading Norwegian manufacturer DNH since the 1980s. The DNH company has an unrivaled reputation for the development and production of high-quality speakers for demanding professional applications. DNH controls the production entirely in-house and has a 100% output control, whereby each loudspeaker produced is thoroughly inspected separately.
DNH speakers market leader in niche markets
85% of all loudspeaker installations on offshore platforms in the North Sea contain DNH loudspeakers. Furthermore, the loudspeakers are used in cruise ships, all types of work vessels, airports, tunnels, trains and metro stations. DNH not only has the highest quality, but also the widest range of loudspeakers for industrial use in the world.
Reliability as the first condition
In environments where communication is or can be critical, it is sometimes of vital importance that one can rely on the functionality and performance of the speakers present. DNH develops and produces very high-quality loudspeakers, which continue to function even under severe or even extreme conditions.
Some characteristic features of the DNH speakers:
- Extremely reliable, each speaker tested individually
- Type approved by, among others, Bureau Veritas
- Wide range for every industrial and commercial application
- Fire retardant, watertight, weatherproof and shockproof variants
- Special loudspeakers for explosive atmospheres (ATEX and IECEx approved)
More than 70 years of experience in speakers
DNH was founded in 1946, shortly after the Second World War, by three Norwegian seafarers. From the start of the company, the aim was to achieve maximum performance and uncompromising quality for every speaker that left the company. In 1962, DNH was the first manufacturer to produce an explosion-proof speaker. Also for other demanding circumstances new products tailored to the task have been developed. For example, speakers have been developed that are resistant to extreme heat, vibrations, salt water, chemical vapors and explosion hazards.
