page 1 MODEL 4,5,8 CONNECTING YOUR SPEAKERS I l I INTRODUCTION ESS Perfonnance Series speakers are among the most effi cient Reil air- motion transformer loudspeakers available; all feature a 10" passive radiator tuned to optimize the bass response in their respective system; all speakers provide the tonal clarity characteristic ofHeil air-motion transformersys terns; all are superb instruments meant to last a lifetime with proper care. We urge you to read this Owner's Manual care fully.
page 2 • The "Left" and "Right" designations on the speaker out put terminals of your amplifier or receiver refer to the speakers as you face them. Thus the Left Channel output of your receiver should be connected to the speaker on your left, and the Right Channel output from the receiver should be connected to the speaker on your right. It is very important that the positive (" +") and (" ") posts of your electronics connect properly to responding speaker posts.
page 3 SPEAKER PLACEMENT A speaker's room placement and its orientation to the listener can have a major bearing on the quality of sound you hear. The proper functioning of the passive radiator at the rear of the model 5 & 8 requires that these speakers be placed no closer than one inch from the wall. Maximum bass perfor mance will probably occur with the speaker placed 3 to 5 inches from the wall.
page 4 LOW FREQCENCY DRIVER THE PASSIVE RADIATOR Different low frequency transducers are used in ESS Perfor mance Series speakers to complement cabinet size and the Heil air-motion transformer. Each woofer utilizes a magnetic circuit that critically damps the drivers moving assembly and makes possible a flat frequency response over an extended range. The model 4 woofer operated from 35 Hz to the cross over point at 2400 Hz into the Heil amt.
page 5 NOTE: In the model 5 and 8 speaker systems you can tune your passive radiator to a lower frequency by mov ing the rear of the speaker enclosure closer w the wall. Maximum bass performance will probably occur with the speaker placed 3 to 5 inches from the wall.
page 6 THE IMPORTANCE OF "CLEAN" AMPLIFIER POWER OUTPUT MULTIPLE SPEAKER CONNECTION The power rating on your ESS Performance Series loudspeaker represents the maximum amount of clean power which the loudspeaker will handle indefinitely. ESS Performance Series speakers have an impedance of 6 ohms. Most receivers and basic amplifiers have no difficulty whatsoever with impedance loads above 4 ohms, but can develop problems if the load drops below 4 ohms.
page 7 HElL ROTATION FOR HORIZONTAL PLACEMENT The Heil air-motion transformer in your ESS Performance Series speaker is mounted for optimal performance in the upright, vertical position. If you plan to lay your model 5 or 8 speake,rs on their longest side in the horizontal "bookshelf" position, then the Heil amt may be rotated 90° in the follow ing manner to optimize dispersion. • Place the speaker on its back.
page 8 LIMITED THREE-YEAR WARRANTY When ESS Performance Speakers are used in accordance with the written instructions contained in the Owner's Man ual, ESS will repair any defect in workmanship and materials that occurs in normal use for a period of 36 months from the date of original purchase without charge for parts or labor. The warranty applies only to the original owner and is con tingent upon purchase from an authorized dealer, except where prohibited by law.
IMPORTANT ESS is constantly researching new materials, production methods and design refinements which may be introduced into product lines without notice or obligation. For this reason, any current ESS Performance Series product may differ in some respect from its published description but will always equal or exceed perfonnance of the original design.
