Lubell Labs LL964C/H
Underwater Speaker (Military / OEM sales only)
The
LL964H (harness mount) and LL964C (cage mount) are
high-performance piezoelectric underwater speakers developed,
patented, and manufactured by Lubell Labs of Columbus Ohio. Because of
the higher impedance of the LL964C/H, long cable lengths with
minimal insertion loss are possible using standard SO cable.
For instance, four LL964C/H underwater speakers each having a
1.5km long 14/2 AWG cable may be connected in parallel (14
ohms) to an amplifier rated at 200 watts @ 8 ohms (40 Vrms)
resulting in a sound pressure level of 177dB/uPa/m at each
transducer. The LL9XX series continue to set the world
record for having the widest frequency response and output level
of any commercial
underwater speaker made, at a price that is both reasonable and
affordable. Because of it's
rugged die-cast aluminum housing with 150 mil PVC overmold, the
LL964C/H may be used in rivers, lakes, and ocean without worry
of corrosion. The LL964C and LL964H are for sale to
OEM manufacturers only. For portable commercial underwater
speakers, please see the Lubell LL916C/H...
and for an in-wall underwater speaker see the Lubell 9484.
