DESCRIPTION

EAW’s JF290z two-way loudspeaker system provides high output, low distortion sound reinforcement for the entire range of pro audio applications.

The newly re-engineered 12-in low frequency cone and 1.4in exit 3-in voice coil high frequency compression driver provides higher output and lower distortion plus enhanced power handling capabilities for better performance in both portable and permanently installed applications. The new constant directivity HF horn – inspired by the new AS Series systems – provides optimized dispersion of HF information without problematic beaming.

EAW’s advanced beamwidth matching crossover selects a crossover point where the HF horn’s beamwidth matches that of the woofer. The result is more even off-axis frequency response (power response) for more complete coverage.

The JF290z offers a switchable powering mode: passive operation using the internal crossover filter network or biamplified operation requiring the use of pre-configured

MX Series processor settings.

APPLICATION

The JF290z was designed to support the widest possible range of pro audio applications and was optimized for use in distributed systems.

The pole mount cup and balance-optimized handles allow for quick and easy load-in of portable uses. Its high output capabilities let it act as a main system for smaller concert or portable A/V events or even provide front or side fill for concert touring applications.

The comprehensive system of integral 3/8”-16 threaded mounting points permit safe, load-rated suspension in permanent installations.

A & E SPECIFICATIONS

The two-way full range loudspeaker systems shall incorporate a 12-in LF transducers and a 1.4-in exit/3-in voice coil compression driver HF transducer.

The LF driver shall be mounted in a vented enclosure tuned for optimum low frequency response. The HF driver shall be loaded on a constant directivity horn with a nominal coverage pattern of 90

°

(h) x 45

°

(v).

A switch shall be provided allowing the user to select between bi-amplified or full range passive powering modes. In full range passive mode, an internal passive filter network shall provide fourth order acoustical crossover and system equalization between the low and high frequency sections.

System frequency response shall vary no more than

±

3 dB from 67 Hz to 17 kHz measured on axis. In full range mode, the system shall produce a Sound Pressure Level (SPL) of 97 dB SPL on axis at 1 meter with a power input of 1 Watt, and shall be capable of producing a peak output of 129.0 dB SPL on axis at 1 meter. In full range mode, the system shall handle 500 Watts of amplifier power (AES Standard) and shall have a nominal impedance of 8 Ohms.

In biamplified mode, the low frequency section shall produce a Sound Pressure Level (SPL) of 96 dB SPL on axis at 1 meter with a power input of 1 Watt, and shall be capable of producing a peak output of 129.0 dB SPL on axis at 1 meter, and the high frequency section shall produce a Sound Pressure Level (SPL) of 105 dB SPL on axis at 1 meter with a power input of 1 Watt, and shall be capable of producing a peak output of 134.0 dB SPL on axis at 1 meter. In biamplified mode, the low frequency section shall handle 500 Watts of amplifier power (AES Standard) and shall have a nominal impedance of 8 Ohms and the high frequency section shall handle 200 Watts of amplifier power and shall have a nominal impedance of 16 Ohms.

The loudspeaker enclosure shall be trapezoidal in shape. It shall be constructed of 1/2-in thickness void-free cross-grainlaminated Baltic birch plywood and shall employ extensive internal bracing. It shall be finished in black catalyzed polyurethane. Input connectors shall be dual Neutrik NL4.
