Tender Specification: IG-100

Compact Ceiling Speaker With 2-way Coaxial Design

Compact, 2-way ceiling speaker, equipped with a 4″ woofer and a coaxial 0.75“ high frequency driver mounted in front. Self-resetting high frequency protection guards the high frequency driver against overload. Able to briefly handle peak power of up to 200 W, the speaker can generate a maximum SPL of 109 dB. Beam dispersion is 100° conical. The frequency range is 85 Hz to 20 kHz.

The ceiling speaker has a powder-coated, steel fire dome enclosure with a maximum installation depth of 99 mm and a flat protection grille. The grille is magnetically attached and can easily be removed.

The ceiling speaker has an integrated 100 V transformer. A selector switch on the front enables low-ohm control, three settings for 100 V systems (30/15/7.5 W) and a complete switch-off. Installation is via three foldout mounting clamps. To secure the speaker in the ceiling, a safety cable can be fitted using the eyelet on the side of the enclosure. Electronic connection is via a cable outlet with a 2-pin twin wire. The ends of the single strand wires are pre-fitted with a flexible 3-pin quick-mount WAGO terminal.
