The IMO compliant Kahlenberg KM-250 is a popular choice for commercial and military vessels measuring between 75m-200m. Ruggedly built to withstand harsh environments and continuous service demands, with a range of 1.5nm and fundamental frequency of 250Hz
The Kahlenberg KM-250 is ruggedly constructed using a cast marine aluminium bell, with stainless steel diaphragm and fasteners.
