D-4A marine air horn
LOA 75m-200m
Kahlenberg Chimetone D-4A
Kahlenberg Chimetone four-series air horns provide superyacht quality sound signals to the increasing number of mega yachts that are being built in the 75m-200m size segment, as well as a wide variety of ships. IMO compliant and suitable for all vessels up to 200m (246ft) overall length.
The Kahlenberg Chimetone D-4A is a two-projector marine air horn constructed entirely out of spun brass and bronze and tuned to 171Hz and 220Hz to provide a harmonic, highly effective sound signal for larger superyachts.
Finished with the finest quality duplex nickel chrome plating, white powdercoat or bare, the D-4A can operate over a very wide range of air pressure, for adaption to ship supply where this is available.
