The Lubell Labs LL9162 is a high-power full-range pistonic piezoelectric underwater acoustic transducer developed and manufactured by Lubell Labs of Columbus, Ohio USA. The LL9162 is intended for scientific and military uses including harbor defense and interrogation of suspicious divers. The LL9162 may be used portably, or permanently mounted at depths from 6 feet to 60 feet in fresh or salt water.
The LL9162 has a useful frequency range of 200 Hz - 20 kHz, a nominal impedance of 16 ohms, and an SPL of 186dB/uPa/m @ 1 kHz and 190dB/uPa/m @ 10 kHz with 50 Vrms applied. The LL-9162 may be connected to a GFCI protected amplifier with a transformer isolated speaker output up to 300 watts @ 8 ohms. An external series resistor and fuse must be used with the LL-9162 (per instructions). Frequencies below 200Hz must be rolled off at 12dB/octave when reproducing broadband. The LL9162 is mounted in a shock-mount protective cage, and is fitted with a Subconn MCBH3MSS underwater pluggable bulkhead connector with mating Subconn 50 foot (15.24m) 18/3 SOOW cable assembly. Custom cable lengths and gauges are available, as well as multi-tap underwater pluggable umbilicals.
