UW30 Underwater Speaker
and Accessories
The
University Sound UW30 underwater speaker is an economical
moving-coil underwater speaker manufactured by Electrovoice, a
division of Bosch
Security and Safety Systems. The UW30 provides a
remarkably uniform (+/- 4 dB) response between 80 Hz - 1300
Hz, with a TVR of 125 dB ref 1 µPa/V @ 1 m. The UW30 is
suitable for activities including: synchronized swimming in
small home pools, marine biology & environmental impact
studies in aquariums and tanks, and relaxation during Watsu
(aquatic massage) and flotation tank sessions. The UW30 is not recommended
for lap swimming in home or commercial pools, or for
synchronized swimming in Olympic pools, as the sound
levels produced by this speaker are not adequate for these
activities. (For these applications, we
highly recommend using the piezoelectric Tonpilz
technology pioneered and patented by Lubell Labs, who's
portable LL916C/H
and permanent 9484
underwater loudspeakers produce at least 8 times the sound
level of the UW30 due to higher efficiencies and
power handling.) The UW30 underwater loudspeaker may be
used in tropical to arctic climates in freshwater or saltwater
by virtue of it's high-impact ABS outer case and flexible
thermoplastic cable.
To insure the safety of
personnel and swimmers at aquatic facilities, the UW30 shall
be mounted in a corrosion-resistant metal forming shell, the
front of which is enclosed by a captive corrosion-resistant
metal speaker grille, which is bonded to and secured to the
forming shell, insuring a low-resistance contact. This
mounting requirement is called out in the 2005 NFPA 70:
National Electrical Code (NEC) Handbook Section 680.27, as well as
in the 2003 International Residential Code (IRC) Paragraph E4106.9.1. In addition,
the UW30 underwater speaker must be connected to a UL or ETL
approved 30-40 watt commercial-sound amplifier's 8 ohm and
Common transformer-isolated speaker terminals labeled "Class
2 Wiring Acceptable"; Amplifier must be installed in dry,
air conditioned area, and it's three-prong grounding power
cord must be connected to a GFCI protected AC outlet which
shall be tested per manufacturer's instructions.
