OEM, military and ocean engineering only

A higher impedance version of the LL916 for acoustic barriers and harbour defence. It runs over very long cables with minimal loss.

Lubell LL964C underwater speaker in a black protective cage

Overview

The LL964C (in a cage) and LL964H (in a harness) are high performance piezoelectric underwater acoustic transducers. They are the high impedance version of the popular LL916, which lets them run on very long cables with little loss.

They work in tanks, rivers and the open sea, and can be special ordered with an underwater pluggable Subconn bulkhead connector.

Highlights

  • 180 dB re 1 µPa at 1 m, 1 kHz
  • 200 Hz to 23 kHz
  • Long cable runs with minimal loss
  • Cage or harness version
