2.5, 10, 20 Watt WATERTIGHT NAVAL LOUDSPEAKERS
NSN 5965-99-537-2183 (VQ85496) & 5965-99-537-2184 (VQ85490)
These loudspeakers for ships, which are current Royal Navy stock items, are primarily for naval use both above and below deck. They comply with the relevant British Standards and UK MoD (Navy) specifications. They are for general use above deck and are also used below deck in noisy areas, such as near propulsion machinery and helicopter loading bays.
They have been type tested by the Royal Navy to 70 G force. This demonstrates their effectiveness in battle conditions where they are able to withstand close proximity explosions and damage. Main broadcast reliability is an essential safety requirement on warships. They also have the critical benefit of being designed and proven to be blast and shockwave proof. This is necessary for both battle conditions and battle simulation where even firing of the ship’s own surface to air missiles will destroy the diaphragm of normal marine loudspeakers.
These marine loudspeakers are used extensively throughout the UK, Australian and New Zealand navies’ and are the main above deck loudspeakers used by the Royal Navy. Their sheer durability and reliability makes them the best choice for communication safety.
