full-range HVC (Helical Voice Coil) driver. The
loudspeaker shall be used for installation on
walls, ceilings, and other flat, solid surfaces.
Each loudspeaker shall have a nominal rated
impedance of 8 ohms and shall be wired in
parallel with a line voltage matching (step-down)
transformer with an accessible, front-mounted
level selector appropriate for setting various
output taps. The loudspeaker input connections
will allow for direct connection to 70V, 100V or
low-impedance amplifiers.
The loudspeaker shall have a protection circuit
to protect the product from occasionally being
overdriven.
Each loudspeaker shall have a bandwidth of
80Hz–16kHzandamaximumacousticoutput
of 103 dB-SPL referenced to a full bandwidth
pink noise input at 1 meter at the loudspeaker’s
rated power. The input connection shall consist
of a three-position barrier connector on the
included mounting bracket. Each loudspeaker
shall be wired to the mounting bracket via a
4-pin, pre-wired connector.
