[. . . ] UNPACKING THE SPEAKERS If you suspect damage from transit, report it immediately to your dealer. Keep the shipping carton and packing materials for future use. NOTE: A JBL powered subwoofer will add impact and realism to both music and film soundtracks. Contact your JBL dealer for recommendations on subwoofer models for your application. JBL Subwoofer (optional) Left Front Channel Right Front Channel Center Channel PLACEMENT NEVER drag the speaker to move it, as this will damage the spikes, the feet and/or the wood cabinet itself. CAUTION: Floorstanding (tower) loudspeakers have a high center of gravity and may become unstable and tip over during events such as earthquakes, or if rocked, tipped or improperly positioned. [. . . ] NEVER drag the speaker to move it, as this will damage the spikes, the feet and/or the wood cabinet itself. Always lift the speaker and carry it to its new location. Place pads here WALL-MOUNTING ES10 The ES10 may be wall-mounted. The customer is responsible for proper selection and use of mounting hardware (available through hardware stores), to properly and safely wall-mount the speakers. THESE PRODUCTS ARE NOT INTENDED FOR CEILING MOUNTING. CHANGING THE FEET ES80, ES90, ES100 The ES80, ES90 and ES100 feature attractive outboard feet, installed at the factory. However, if you would like to replace them with the less visible inboard feet (included), follow the instructions below. Remove the four feet on the bottom of the speaker by loosening the two screws in each foot. Keep the screws for later use. 10" (254mm) 1/8" (3mm) Two no. The screw head should be between 5/16 inch (8mm) and 1/4 inch (6. 3mm) in diameter, and the screw should be at least 2 inches (50mm) in length. When installing screws in any wall, always use properly selected wall anchors. Attach two of the four self-adhesive rubber pads that came with the loudspeaker to the back of the enclosure in the two bottom corners so that the cabinet is spaced evenly from the wall. (The ceiling is not a suitable mounting location. ) Drill two pilot holes, appropriately sized for the specific self-tapping screw or wall anchor that you will be using. The holes should be 3/4 inch (19mm) below where you want the top of the enclosure to be positioned. Use a carpenter's level to ensure that the holes are even and that the speaker will mount on the level. 2. Attach the black inboard feet to the outer (closest to front of speaker for front feet, closest to rear of speaker for rear feet) holes, from which you just removed the feet, using the same screws you just removed. Do not use a powered screwdriver of any type. Install the two screws into either a wooden wall stud or anchor, and tighten them until the back of each screw head is about 1/8 inch (3mm) from the wall. Install the loudspeaker by slowly moving the cabinet toward the screws so that the screw heads clear the larger circular portion of the two keyholes. Once both screw heads have entered the keyholes, the loudspeaker should gently be lowered onto the screw shafts. Check that the loudspeaker is firmly locked onto the screws by gently pulling the speaker down and forward. 4. CAUTION: Floorstanding (tower) loudspeakers have a high center of gravity and may become unstable and tip over during earthquakes, or if rocked, tipped or improperly positioned. If this is a concern, these speakers should be anchored to the wall behind them, using the same procedures and hardware customary for anchoring bookcases and wall units. The customer is responsible for proper installation and proper selection of hardware. 3 WIRING THE SYSTEM IMPORTANT: MAKE SURE ALL EQUIPMENT IS TURNED OFF BEFORE MAKING ANY CONNECTIONS. [. . . ] Wiring diagram shows polarity connections for one channel of a stereo or home theater system. Listen to a variety of music selections and note the bass level. Conversely, if you place the speakers closer to the walls, there will be more bass output. BI-WIRING ES30, ES80, ES90, ES100 The outer connection panel and internal dividing network of the ES30, ES80, ES90 and ES100 are designed so that separate sets of speaker cables can be attached to the low-frequency transducer and midrange/high-frequency transducer portions of this dividing network. Bi-wiring can provide several sonic advantages and considerably more flexibility in power amplifier selection. CARE OF YOUR SPEAKER SYSTEM Each JBL ES Series enclosure has a finish that does not require any routine maintenance. When needed, use a soft cloth to remove any fingerprints or dust from the enclosure or grille. [. . . ]
