User manual JBL RIF5

[. . . ] The curvaceous TiK form is the result of a complex wood molding process developed by expert Scandinavian furniture builders. Tightly controlled curvature and extreme structural integrity are achieved by bonding seven layers of MDF under high pressure, resulting in a material more rigid than a wood panel of comparable thickness. The slender front panels provide diffraction damping and reduce the effects of edge reflections, creating an ideal platform for the custom-designed JBL TiK drivers which are flush-mounted in the 25 mm MDF front panel for an air-tight seal using non-magnetic stainless steel screws. In order to convey the open, airy "sweetness" of the upper frequency range, the TiK Series highlights perhaps the most advanced dome tweeter in the world, taking the remarkable achievement of JBL's pure Titanium dome driver technology a giant step further. [. . . ] The pure Titanium dome is terminated in a soft surround which places the driver's resonant frequency well outside its operating range. To prevent the build-up of a disruptive captive air mass beneath the dome, the driver incorporates a rear pressure vent. Exceptional efficiency is achieved through the use of an aluminum voice coil with 50% lower mass than a typical coil employing more common copper windings. With a pure Titanium dome which acts as an effective heatsink for the voice coil, the TiK high frequency driver surpasses the competition in all critical areas: smoothness, transparency, efficiency, power handling and transient response. JBL engineers devised a novel midrange driver based on a 4" inverted dome of pure Titanium to seamlessly blend with the pure Titanium dome tweeter in the Ti10K and Ti6K. The inverted Titanium dome offers near-perfect pistonic motion, virtually eliminating distortion caused by break-up modes which occur when more conventional cone materials flex uncontrollably. Driven by a powerful neodymium magnet mounted inside the large (37 mm) voice coil, the magnetic system provides its own magnetic shielding. Fitted with spikes, the TiK speakers are immune to resonances in the floor itself, enabling them to deliver more controlled, dynamic deep bass and a more stable and accurate stereo image. Every loudspeaker in the TiK Series is based on the same driver, enclosure and crossover technologies which led one reviewer to name the Ti10K "The best JBL loudspeaker ever. " All drivers and cabinets originate in JBL's own advanced design and assembly facilities. An electro-plated film of pure Titanium on each TiK driver chassis adds a distinctive sheen to the rim of each driver. Isolated bass sub-enclosures with minimal acoustic damping in the Ti10K and Ti6K prevent interaction with the other drivers and contribute to the extreme dynamics and transient speed of the TiK Series. Inside surfaces are coated with a bituminous material for additional resonance damping of the enclosure. The low-loss phase-coherent crossover networks mounted in the loudspeaker base incorporate high quality internal wiring, sonically neutral compo0nents and time alignment circuitry. Input terminals are mounted directly on the crossover board for the shortest possible signal path. Specifications Ti10K: Rec.
