LL1424HP

Science and defence customers only

A high power broadband underwater transducer for marine science, sub bottom profiling, acoustic deterrence and defence, and an underwater speaker wherever very high power is needed.

Lubell LL1424HP transducer in a stainless cage beside its AC1424HP transformer box

Overview

The LL1424HP is a piezoelectric underwater acoustic transducer for applications that need a lot of sound: marine biology, sub bottom profiling, acoustic and diver deterrent systems, and general military and scientific work.

It is built for the ocean, with an epoxy finish and a 316 stainless steel cage. It comes with an AC1424HP bridging transformer box, which connects it to amplifiers of up to 2500 W at 4 Ω bridged mono, and a Subconn cable that plugs into the transducer’s bulkhead connector.

Highlights

  • 197 dB re 1 µPa at 1 m at 600 Hz
  • Stainless steel protective cage
  • AC1424HP bridging transformer box included
  • Pressure fitting option for depths beyond 12 m
