CD18

NEXO R&D has used the advanced DSP power of the digital NX242 TDcontroller to develop an extremely compact and highly efficient method for controlling the dispersion of very large acoustical waves.
The CD18 uses a pair of long excursion neodymium 18in drivers, two amplifier channels and two channels of DSP processing to generate a cardioid or supercardioid pattern with up to -15dB of attenuation at the rear. Yet, the enclosure is no larger than is required for proper loading of the transducers. CD18's deliver high-impacT Subbass energy to the audience while keeping very low frequencies away from open Microphones and reflective/reverberant surfaces. The end result is a much more controlled and coherent foundation for the mix, as compared with conventional Subwoofers.

Used Nexo

NEXO are among Europe's top three sound reinforcement loudspeaker manufacturers. Based in Paris, the company was founded in 1979 by Eric Vincenot and Michael Johnson. Both are still actively involved with the company and Eric maintains the unique role of Chairman and R&D Director. What separates NEXO from the competition is an innovative, integrated systems approach to loudspeaker research and development. Each new product/system begins with sophisticated computer simulations, executed by our highly specialised proprietary software. After the design specification stage, the entire electro-acoustic signal chain is thoroughly modeled and product performance rigorously evaluated to maximize system performance in an incredibly short time frame.

Used Line Array Speakers

Line array speakers make up a loudspeaker system to create a sound source that produces an evenly distributed sound output. The driver of each line array element is close enough to the driver of the next element to create constructive interference. The resulting sound waves go farther than sound waves from traditional loudspeakers. Line array systems date back to the early days of research in acoustics. Many old town halls and public venues still have old line source boxes which were found to project voice well though they are much smaller than horn-loaded speakers. These days, line array speakers use different drivers for high-, mid- and low-frequency passbands that must be in line. Each enclosure must be set up closely to form columns composed of these drivers. To increase the frequency range and maximum sound pressure, the number of drivers per enclosure must be increased. The orientation of line array speakers may vary. Vertical arrays are excellent for focusing sound at audiences without wasting output energy on ceilings or empty air above the audience because of its very narrow vertical output with a normally-wide horizontal pattern. On the other hand, horizontal line arrays have a very narrow horizontal output with a tall vertical pattern. For hanging concert speakers which are usually part of a concert reinforcement system, enclosures are set up together using a specialized rigging hardware and they hang from a single point. These line array speakers are curved backward at the lower portion so that the sound will reach more audience.
