CF108 Series
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.
