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.

Power settings available shall be: 2.5W, 5W,

10W, 20W, 40W @ 70V; 5W, 10W, 20W, 40W

@ 100V; and 40W @ 8Ω (when referenced to

IEC noise for 100 hours). The nominal dispersion

shall be 125° H x 125° V coverage pattern at -6 dB

(average 1 – 4 kHz).

When used with optional junction boxes (wall-

mount bracket variant only), ceramic terminals

and thermal fuse, the loudspeaker shall meet
