[. . . ] This JBL flagship loudspeaker utilizes the company's most advanced technologies, components and materials, incorporating more than 60 years of JBL loudspeaker design expertise. ® ® Highlights Superbly detailed Outstandingly dynamic and capable of breathtaking power Delivery of uniform sound to the listening area Luxurious presence High-performance components Key Specifications Description: Three-way floorstanding speaker Frequency response: 45Hz ­ 50kHz (­6dB) Crossover frequencies: 800Hz/10kHz Power handling: 400 Watts RMS Bass extension: 35Hz (­10dB) Sensitivity (2. 83V@1m): 92dB Nominal impedance: 8 Ohms Dimensions (H x W x D): 1295mm x 508mm x 375mm (51" x 20" x 14-3/4") Weight: 90kg (198 lb) K2 ­ S9800SE ® Cutting-edge-technology loudspeakers Features Employs a 380mm (15") (1500AL) woofer with ribbed Aquaplas-coated pulp cone and Alnico magnet and 100mm (4") edge-wound voice coil. Aquaplas applied to the rear periphery of the cone helps to eliminate distortion at high power levels. [. . . ] Aquaplas applied to the rear periphery of the cone helps to eliminate distortion at high power levels. A Symmetrical Field Geometry (SFG) circuit creates vertical symmetry and generates a constant magnetic-flux density across the width and length of the voice-coil gap. TM The 75mm (3") beryllium (435Be) high-frequency compression driver features an Aquaplas-coated diaphragm and 25mm-throat Bi-Radial horn. ® The 25mm (1") beryllium (045Be) super-tweeter compression driver is mounted in a 12. 8mm- (0. 5"-) throat Bi-Radial horn. The K2 S9800SE crossover can be bypassed for active bi-amplification via an external crossover. Board material is the highest-quality glass-epoxy. The network is carefully tuned for changes in the use of high-quality capacitors. The newly adopted high-quality "fast capacitor" reduces distortion further and results in even more transparency and a richer soundstage. TM Three-step bass adjustment, theree-step treble adjustment and normal/bi-amp switching are possible with control switches on the network panel. Large, extruded stainless steel-feet with selectable round and spike tips.
