GENERAL PRODUCT DESCRIPTION  
The Altec Lansing Professional CF108 series is the result  
of significant research into the applications of speech  
intelligibility and high fidelity music reproduction. The  
CF108 speakers are an excellent choice for standard ceiling  
height applications in educational facilities, shopping malls,  
restaurants, office buildings and commercial facilities. The  
moisture resistant 8 inch / 200 mm speaker features a  
corrosion-resistant speaker frame. To aid in the dispersion  
of higher frequencies, the loudspeaker employs an  
acoustically isolated free-edge HF cone. The 4 watt  
25 V / 70 V transformer has a low <1 .0 dB insertion loss.  
Our international versions feature a < 0.6 dB insertion loss  
4 W 70 V/100 V transformer. For convenience, the WG  
version features a factory-installed corrosion-resistant grille.
