JBL Control NOW - speaker

Key Features and Benefits: One speaker, dozens of possibilities The shape of the JBL Control NOW speaker makes it perhaps the most flexible speaker ever developed. Mounting options for single speakers and multispeaker arrays are literally too numerous to list in detail. But just to get you thinking in the right direction, here are a few possibilities. Single speakers may be mounted horizontally or vertically on walls, and in corners between walls, or between walls and ceilings. They can sit horizontally or vertically on a shelf or tabletop. And everything a JBL Control NOW speaker can do, JBL Control NOW AW speakers can do outdoors. Use them in traditional stereo setups, for home theaters or for whole-house-music and background-music systems. Forget the usual technical challenges that come with wiring multiple-speaker systems. JBL Control NOW speakers eliminate impedance restrictions with a wiring adapter that makes configuring multi-unit arrays simple. High-frequency transducer waveguide design JBL Control NOW speakers can go places where other speakers cannot. Corner-mounting and some multi-unit configurations would sometimes cause unwanted sound reflections that would normally adversely affect frequency response across the listening area. It' a common problem in professional installations, and JBL engineers have addressed it with an adaptation of its patented Bi-Radial horn, a proven technology that strictly controls the directivity of high-frequency sound. For JBL Control NOW speakers, a Bi-Radial-horn profile with smoothly blended edges was developed to minimize diffraction artifacts. The result is remarkably wide and uniform high-frequency response, which is also exceptionally smooth. It's a high-efficiency design for maximum power handling, minimal thermal compression and very little magnetic flux leakage. Low-frequency transducer design JBL Control NOW speakers' low-frequency transducers deliver an ideal combination of enhanced power handling and output, with reduced distortion. Finite Element Analysis was used to optimize motor strength and motorstrength symmetry. Dual neodymium boron-iron magnets are used to increase magnetic flux in the gap, and to provide greater magnetic saturation of the pole plate, which reduces flux modulation and harmonic distortion. The large contact area between the motor and the transducer frame allows the frame to act as a heatsink, dissipating thermal energy and improving reliability during high-output program peaks. Finite Element Analysis was also used to improve the suspension geometry of both the spider and the surround, reducing harmonic distortion. The spider employs a progressive-roll design, and the surround incorporates unique features such as variable-roll thickness and linear surround transition, contributing to the outstanding performance characteristics of JBL Control NOW loudspeakers. System acoustical design As you would expect, the frequency response of JBL Control NOW speakers is optimized for maximum placement flexibility, particularly relative to walls, ceilings and corners. The speakers have constant-directivity characteristics when wall-mounted, and omnidirectional characteristics when corner-mounted or grouped in a four-speaker circular array. The Straight-Line Signal Path (SSP) dividing network ensures accurate reproduction along the shortest possible signal path by employing only the highest quality network components. Mechanical design Enclosures and baffles are constructed of a thermoplastic composite material containing both glass and mineral fill. It's exceptionally stiff, yet well damped, and enclosure walls are double-thick (1/4"). A highly integrated mechanical design uses die-cast aluminum lock plates, port tubes - and even the electrical network board itself - to augment rigidity and structural integrity, further reducing unwanted resonances and acoustical loss.
