Kahlenberg T-4A marine air horn in chrome

The Kahlenberg Chimetone T-4A is a three-projector marine air horn constructed entirely out of cast bronze and brass. It offers a deep, sonorous bass trumpet at 134Hz, plus 171Hz and 220Hz to provide a harmonic, highly effective sound signal for larger superyachts and ships.

Finished with the finest quality duplex nickel chrome plating, or offered in other finishes including bare metal, the T-4A is heavily engineered, virtually maintenance free and can operate over a very wide range of air pressure, for adaption to ship supply.
