By following the steps below, a majority of loudspeakers can be returned to their originalfactory performance with minimum effort. Choose the example that best describes the problem you are experiencing.Problem 1: No sound or distorted sound from one loudspeaker in a pair (or set)Connect the dead/distorting loudspeaker to a different amplifier channel (one that had a functioning loudspeaker connected to it). If it functions normally, theproblem is not loudspeaker-related. If the loudspeaker still makes no sound or sounds distorted, a wire may have become loose or disconnected, the network (alsoknown as a crossover) may be defective, the drivers (woofer, tweeter, etc.) may be defective or, in very rare cases, all may be defective.Refer to the wiring diagram and exploded view below. The network is a small circuit board found on the inside of the terminal cup, or mounted to an inside wall ofthe enclosure. It sends low-frequency sounds to the woofer, high-frequency sounds to the tweeter and, if applicable, mid-frequency sounds to the midrange driver.Make sure all wires are secure and connected. Look for components on the network that look burnt, “bulged,” or abnormal. If everything looks normal, connect thenetwork to the drivers from another matching loudspeaker. MAKE SURE you attach the correct wires to each driver – mid- and low-frequency sounds can damagethe tweeter! If there is still no sound or distorted sound, the network is defective. If there is clean undistorted sound, the drivers are defective.Problem 2: No sound or distorted sound from one or more (but not all) drivers in an enclosureRemove the problem driver(s) from the enclosure and make sure all wires are secure and connected. If they are, proceed with the following test:Woofer or midrange driver – Connect the driver’s + and – input terminals directly to the loudspeaker wires from your receiver/amplifier and play some music ata reasonable volume. If the driver now sounds normal (produces a clean, undistorted sound), the network is most likely defective.Tweeter – Replace the tweeter with a functioning tweeter from another loudspeaker. If the tweeter now functions normally (produces clean, undistorted sound),the original tweeter is defective. If the replacement tweeter also sounds distorted or produces no sound, the network is most likely defective.Problem 3: Loudspeakers distort, rattle or pop at higher volumesThis is usually NOT a loudspeaker problem. Common causes are too much power (playing the loudspeakers too loud and causing them to distort), an amplifierwith not enough power (the amplifier can’t produce the required volume without distorting), excessive equalization (turning the tone controls too far clockwise,and/or engaging the loudness/bass boost button on your receiver) or some combination of the above. If only one loudspeaker is exhibiting the problem, and you’reconfident that it’s not caused by too little power/too much power/excessive equalization, see solutions for Problems 1 and 2.Note: A Phillips screwdriver and 3mm Allen wrench (hex key)are required to service this product.EXPLODED VIEWTWEETER SERVICING:The tweeter on the JBL Stage resides behind the silver faceplate affixed to the front baffle with a pin/cup arrangementsimilar to a front grille. After the grille removal, to access the tweeter, use a box cutter, knife or similar tool to workthe top portion of the silver faceplate away from the front baffle - USE CAUTION. Once the top edge is detached (seeimage), work the tool carefully down the length of the faceplate until it can be removed completely. If the faceplate isaccidentally damaged during this process, order JBL part number 301-ABS-05040-0VAE.ITEMNO. PART NO.
