ENCLOSURES AND BAFFLES

The CF108-series ceiling speakers will fit on standard 8 inch (200 mm) baffles, enclosures and back boxes.

All measurements were made in a standard AES baffle for

a 12 inch driver. The driver was housed in a 1.0 ft3 (0.028 m3) enclosure.

Please note that larger volume enclosures will result in altered low frequency performance.

SAFETY CONSIDERATION

1.Appropriate connectors with suitable ratings must be used to make all installation connections.

2.All unused taps must be insulated with suitable insulation.

3.Transformers and speaker combinations must be supplied by a suitable amplifier incorporating ungrounded outputs only and reinforced insulation (as per IEC60065) from output to mains.

ACCESSORIES

Altec Lansing recommends use of our 8 inch (200 mm) round and square metal enclosures, grilles and tile bridge. The CF108 Series will also fit on standard industry ceiling speaker hardware.
