User manual JBL HARMONY

[. . . ] Four metal spikes are supplied for use when the speaker is to be placed on a carpeted surface to decouple the speaker from the floor. To insert the spikes, gently lay the speaker on its side (not its front or back) on a soft, nonabrasive surface. Each spike screws into the threaded insert in the center of each rubber foot. [. . . ] Each spike screws into the threaded insert in the center of each rubber foot. 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 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. WIRING THE SYSTEM IMPORTANT: Make sure all equipment is turned off before making any connections. For speaker connections, use a high-quality speaker wire with polarity coding. The side of the wire with a ridge or other coding is usually considered positive polarity (i. e. , +). NOTE: If desired, consult your local JBL dealer about speaker wire and connection options. · Turn off all electronics and switch the speaker in question with one of the other speakers that is working correctly. Turn everything back on, and determine whether the problem has followed the speaker or has remained in the same channel. If the problem is in the same channel, the source of the problem is most likely with your receiver or amplifier, and you should consult the owner's manual for that product for further information. If the problem has followed the speaker, consult your dealer for further assistance or, if that is not possible, visit www. jbl. com for further information. · Check all wires and connections between receiver/amplifier and speakers. · If more than one pair of main speakers is being used, check the minimum impedance requirements of your receiver/amplifier. If there is no (or low) bass output: · Make sure the polarities (+ and ­) of the left and right "Speaker Inputs" are connected properly. · Consider adding a powered subwoofer to your system for use with digital ". 1" surround formats. 3 SPECIFICATIONS Maximum Recommended Amplifier Power* Power Handling (Continuous/Peak) Nominal Impedance Sensitivity (2. 83V/1m) Frequency Response Crossover Frequencies Ultrahigh-Frequency Transducer High-Frequency Transducer Midrange Transducer Mid-Bass Transducer Low-Frequency Transducer Magnetic Shielding Terminals Dimensions (H x W x D) Weight per Speaker 250W 125W/500W 8 Ohms 92dB 32Hz ­ 40kHz (­3dB) 280Hz, 1. 2kHz, 4. 5kHz, 20kHz 19mm (3/4") Mylar ® Dome 25mm (1") Pure-Titanium Dome in JBL EOSTM Waveguide 100mm (4") PolyPlasTM Cone With Rubber Surround and Cast-Aluminum Chassis; HeatScapeTM Motor Structure 150mm (6") PolyPlasTM Cone With Rubber Surround and Cast-Aluminum Chassis; HeatScapeTM Motor Structure 300mm (12") PolyPlasTM Cone With Rubber Surround and Cast-Aluminum Chassis; HeatScapeTM Motor Structure; Symmetrical Field GeometryTM (SFGTM); High-Temp. , Oversized Kapton® Voice Coil; Magnetic Shorting Ring Yes Gold-Plated Binding Posts, Bi-Wirable 1194mm x 508mm x 330mm (47" x 20" x 13") 38. 2kg (84 lb) * The maximum recommended amplifier power rating will ensure proper system headroom to allow for occasional peaks.
