Item number: 1029-XXXXX

The IG-100 is a professional ceiling speaker with a 2-way coaxial design. Equipped with an integrated transformer and selector switch, the loudspeaker can be operated both with low-ohm control as well as in various 100-volt systems. With its flame-resistant metal housing and flat protection grille, it can be integrated seamlessly and inconspicuously.

Main features

  • 4" woofer with superimposed 0.75" tweeter
  • Low installation depth of only 99 mm, ceiling cut-out 176 mm
  • Frequency range: 85 Hz – 20 kHz
  • Integrated crossover with high frequency protection
  • Exceptionally even dispersion (100° conical)
  • Integrated 100 V transformer with a 5-step switch (16 ohms; 100V (30 / 15 / 7.5 W); off)
  • Three rotating mounting clamps plus safety latch on the enclosure side
  • Magnetically attached protection grille, can be easily removed
  • Enclosure color black, standard color for front grille and frame: white
  • Alternatively available in various colors (RAL, Pantone, NCS) as well as easy to paint / laminate
