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.
