EAW NT59 - Manual (Page 12)

NT loudspeakers are designed to meet the requirements and demands of portable
applications as well as permanent installations. The integral electronics are based on proven,
high efficiency amplifier technology, with field-replaceable amplifier modules. The
loudspeakers need to be connected to an ac mains supply and a line level audio signal. The
internal DSP is factory preset to provide correct and consistent performance.

The 2-way NT loudspeakers are available in both 12-inch and 15-inch LF driver formats.
Different beamwidths are offered to meet typical coverage requirements in their intended
applications. The trapezoidal design of the enclosures makes them easy to use as a main PA
loudspeaker or as a floor wedge for stage monitor applications.
A companion NT subwoofer is engineered to complement the NT full-range loudspeakers.
It extends the low frequency response of an NT full-range system and increases the output
capabilities at low frequencies. The drivers are installed so one is facing into the enclosure,
but connected with opposite polarity so both cones move in the same direction. At high
output levels each cone "loads" the other in the opposite direction to smooth out any
mechanical asymmetries. The result is significantly reduced distortion.

As is true of all professional loudspeaker systems, the performance of the NT Series
loudspeakers depends on amplifiers delivering an adequate supply of clean power. To
maximize performance, the full-range loudspeakers are bi-amplified, meaning the LF and HF
drivers each have their own signal processing and built-in, high-efficiency amplifier. The
subwoofer is dual-amplified, meaning each driver has its own, built-in, high efficiency
amplifier.
