1. High Efficiency. Modest amplifiers or receivers will be able to produce acoustic levels normally associated with amplifiers of substantially higher power ratings. 2. Cast Frame Woofer. The aluminum die cast woofer frame offers more rigidity than a stamped steel frame. The stronger frame provides a solid foundation for the magnet assembly and cone & coil resulting in a more linear woofer movement and less distortion. With the aluminum frame there is no loss of flux from the magnet assembly (as is the case with steel frames) allowing the voice coil to receive the full strength of the magnetic field. 3. Titanium Laminate Tweeter. Reproduces high-frequency sound waves with accuracy, bringing out clarity and realism. 4. Tuned Port Bass Design. Extends lowfrequency response, reduces distortion and improves power handling capacity.
For the best stereo reproduction, the two loudspeaker systems should be an equal distance from your listening position and separated so that the angle between them, at the listening position, is between 40 and 60 degrees (see Fig. 1). For example, if your listening position is 8 to 12 feet (2.5 to 4 m) from each speaker, the two systems should be about 8 feet (2.5 m) apart. Placing the loudspeakers in corners or against a wall will result in the strongest (not necessarily the most accurate) bass. The CF80 is ported on the front to allow placement directly up against a bookshelf or wall. Since the other CF Series models are ported on the back panel, do not place these speakers closer than 12 inches (305 mm) to the wall behind it if possible.
