The Lubell LL9161 Underwater Acoustic Transducer is designed for general purpose military and scientific applications requiring higher sound levels than the standard commercial LL916.

The LL9161 withstands extreme conditions by virtue of its rugged PVC and stainless steel construction. The LL9161 includes an underwater pluggable SJOW cable that can be field replaced by the operator. The LL9161 operates at depths between 6' to 50' in freshwater or seawater.

Because the LL9161 presents a reactive load, it must be powered by an amplifier having Class AB topology (such as the Bosch PLE-1P240) which can deliver up to 31 Vrms on it's 4 ohm output).
