6、ea. Horizontal and vertical dispersion usually vary with 2- way speakers, so installation orientation should be consistent. Models A6 and A8 deliver about 110 and 100 degrees of horizontal sound coverage, respectively, while the coaxial A2 provides about 80 degrees. Too great a distance between any

7、2 speakers will create a dead spot in the coverage. When in doubt, use more speakers to ensure adequate coverage. OTHER FACTORS TO CONSI DER Distance is not the only factor affecting sound intensity. Others that should be considered in the planning phase are adjacent surface reinforcement and enviro

8、nmental effects such as temperature extremes and humidity (mainly in outdoor installations) . LOW FREQUENCY OUTPUT Bass output level depends on a speakers location. The more reflecting surfaces in proximity to the speakers (walls, ceilings, floors) , the greater the bass output. Therefore, speakers

9、mounted in free space (e. g. , hanging from an overhead support) will produce comparatively less bass output. UNDERPOWERI NG VS. OVERPOWERI NG Most speaker damage is caused by amplifiers with too little power. An overdriven amp sends clipping distortion to the speakers. Clipping is usually audible;

10、it may vary from a harsh sound to a fuzzy or blurry sound. I f you hear clipping at loud volume levels, turn down the volume until the distortion is no longer present. Damage caused by operating the speakers at distorted volume levels is not covered by the warranty. PAI NTI NG The speaker cabinet an

Then, if desired, spray the grille lightly to avoid plugging the holes. MAI NTENANCE None required. Speaker cabinets can be wiped clean with a soft, damp cl

12、oth. NOTE: The total number of speakers multiplied by the tap value cannot exceed the output power (in watts) of the 70V amplifier. The above example shows 5 speakers. Using the 16W taps, you need an amplifier with at least (5) x (16) = 80W. A good rule of thumb is to select an amplifier with 20% gr

13、eater power; in this case, an amplifier that delivers about 100W. Observe correct polarity for maximum bass performance.
