WS 620XT
WATERPROOF SPEAKER FOR FLUSH-MOUNTING
DESCRIPTION
WS620XT is a ceiling speaker that can be
flush-mounted in false ceiling or panels. It has
been designed for external use, even on
boats. WS620XT incorporates a 160 mm (6”)
loudspeaker, with a 25 mm (1”) coaxial
tweeter. The speaker is equipped with a line
transformer that enables direct connection to
constant voltage systems at 70 V or 100 V. It
is possible to use the low impedance taps (4
ohm) removing the transformer. In this case
the installation can be done even with
reduced depth.
FEATURES
• Weather resistant splashproof speaker
