6. g a conservative design approach for the crossover long life capacitors and low loss low distortion inductors along with stranded hook up wire that will not fracture with road handling the crossover is as durable as the drivers The Model 100S has a four position high frequency control with attenuation capability from acoustically flat to 9 dB in 3 dB steps This control allows for individual preferences or for compensation in different room environments and it is conveniently recessed into the back panel Also on the back panel are dual Y inch input jacks that facilitate the parallel connec tion of multiple Model 100S s There are two precautions however First be certain to employ interconnecting cables that maintain proper relative polarity between any two systems For example if the coded lead is connected to the tip of the Ys inch phone plug at one end of the cable the same connection should be made to other end of the cable Second the impedance changes that result from parallel connection must be kept in mind A single 100S has a nominal 8 ohm impedance When two units are connected in parallel by using the paralleled input jacks the impedance drops to 4 ohms By paralleling additional 100S units the combined impedance will continue to drop example 3 units 2 7 ohms 4 units 2 ohms Many power amplifiers will not drive loads under four ohms so consult the appropriate owner s information The Enter
7. ion in the sound field determines the amount of acoustic power output required of the speaker system to produce a certain sound pressure level at the listener s ears Generally speaking the amount of power output needed from the speaker amplifier system decreases as the room becomes smaller and or more reverberant The frequency response of the overall system can be adversely affected by poor placement of the speakers themselves For best results the speaker system should be mounted on speaker stands away from floor ceiling or wall surfaces POWER HANDLING Power handling specifications are meaningful to the extent that the nature of the test signal relates to actual use The 100 watt specifica tion for the 100S is based on filtered random noise FM interstation noise and tape hiss are common forms of random noise which is fed to the speaker for an extended time more than 15 hours Random noise testing is used because like real music and speech program material it contains many frequencies Low frequencies which cause large excursions of the woofer suspension are present as well as mid bass frequencies which contribute mainly to woofer voice coil heating Thus the woofer is simultaneously tested for mechanical fatigue and voice coil overheating Similarly the tweeter is tested for both mechanical and thermal failure at appropriate power levels MAXIMUM ies Be wevensonaer TTI CEES LT ay RE EAR ARSE room consta
