GENERAL PRODUCT DESCRIPTION  
The Altec Lansing Professional CD408 series uses Duplex®

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

and magnetic isolation. The optional 70 V / 100 V transformers  
(4, 8, 16, 32 Watts) feature a low < 0.6 dB insertion loss.
