CD408 SERIES
GENERAL PRODUCT DESCRIPTION
The Altec Lansing Professional CD408 series uses Duplex®
technology to maximize the reproduction of high output music
program material. The CD408 is an excellent choice for clubs,
restaurants, performance and transportation venues and all
applications requiring high output and high fidelity performance.
The loudspeaker consists of an 8 inch / 200 mm special moisture
resistant cone woofer, a broad dispersion cone tweeter with heat
resistant voice coils and a corrosion-resistant speaker frame. A
2,500 Hz first order crossover provides smooth high fidelity
transitions. The double magnet design allows physical, electrical,
and magnetic isolation. The optional 70 V / 100 V transformers
(4, 8, 16, 32 Watts) feature a low < 0.6 dB insertion loss.

ENCLOSURES AND BAFFLES
The CD408-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 CD408 Series
will also fit on standard industry ceiling speaker hardware.
