DESCRIPTION

• Compact loudspeaker with no compromise in sound quality

•

For portable use or permanent installation

•

100° conical beamwidth

• Passive crossover for single amplifier operation

The JF60z is an ultra compact loudspeaker, engineered for
exceptional, near-field performance. It provides surprisingly high
output and exceptional fidelity for foreground and background music
applications. It's speech projection capabilities also make it very
effective as a fill or delay element in larger audio systems. Unlike
many compact loudspeakers, the JF60z produces the high impact,
high definition sound projection expected in professional PA
applications. Its wide angle projection makes audience coverage
easy in a variety of situations. While the JF60z is well suited as is for
many applications, the addition of a subwoofer can expand its
capabilities for more demanding applications.

Foam-backed grilles hide the drivers from view for pleasing
aesthetics. T op, bottom and side mounting points allow enclosures to
be mounted in virtually any configuration using eyebolts or accessory
brackets. Additional mounting points accept an OmniMount® 30.0
Series or similar bracket and a third-party , external, stand adapter for
pole mounting, such as the K&M™ 195/8 or Ultimate Support™
BMB-200K. Standard colors are black and white. Other colors can be
specified as a special order items.

The diverse applications for the JF60z include: band PA, multimedia
systems, retail spaces, presentation suites, shopping malls, smaller
houses of worship, theatres, auditoriums, lecture halls, and theme
parks. Fill/delay applications include arenas, stadiums, concert halls,
theatres, and houses of worship.

Six year warranty.

NOTES

TABULAR DA T A

1. Measurement/Data Processing Systems: Primary -FChart: proprietary EAW software;Secondary - Brüel & Kjær 2012.

2. Microphone Systems: Earthworks M30; Brüel & Kjær 4133

3. Measurements: Dual channel FFT ; length: 32 768 samples; sample rate: 48 kHz; logarithmic sine wave sweep.

4. Measurement System Qualification (includes all uncertainties):SPL: accuracy +/-0.2 dB @ 1 kHz, precision +/-0.5 dB 20 Hz to 20 kHz, resolution 0.05 dB; Frequency: accuracy +/-1 %,

precision +/-0.1 Hz, resolution the larger of 1.5 Hz or 1/48 octave; Time: accuracy +/-10.4 µs, precision +/-0.5 µs, resolution 10.4 µs; Angular: accuracy +/-1°, precision +/-0.5°, resolution 0.5°.

5. Environment: Measurements time-widowed and processed to eliminate room effects, approximating an anechoic environment. Data processed as anechoic or fractional space, as noted.

6. Measurement Distance: 7.46 m. Acoustic responses represent complex summation of the subsystems at 20 m. SPLis referenced to other distances using the Inverse Square Law.

7. Volts: Measured rms value of the test signal.

8. Watts: Per audio industry practice, “loudspeaker watts” are calculated as voltage squared divided by rated nominal impedance. Thus, these are not True Watt units of energy as defined by

International Standard.

9. SPL: (Sound Pressure Level) Equivalent to the average level of a signal referenced to 0 dB SPL= 20 microPascals.

10. Subsystem: This lists the transducer(s) and their acoustic loading for each passband. Sub = Subwoofer, LF = Low Frequency , MF = Mid Frequency , HF = High Frequency .

11. Operating Mode: User selectable configurations. Between system elements, a comma (,) = separate amplifier channels; a slash (/) = single amplifier channel. DSP= Digital Signal Processor.

IMPORTANT: T o achieve the specified performance, the listed external signal processing must be used with EA W-provided settings.

12. Operating Range: Range where the processed Frequency Response stays within -10 dB SPLof the power averaged SPLwithin this range; measured on the geometric axis. Narrow band
dips are excepted.

13. Nominal Beamwidth: Design angle for the -6 dB SPLpoints, referenced to 0 dB SPLas the highest level.

14. Axial Sensitivity: Power averaged SPLover the Operating Range with an input voltage that would produce 1 W at the nominal impedance; measured with no external processing on the

geometric axis, referenced to 1 m.

15. Nominal Impedance: Selected 4, 8, or 16 ohm resistance such that the minimum impedance point is no more than 20% below this resistance over the Operating Range.

16. Accelerated Life T est: Maximum test input voltage applied with an EIA-426B defined spectrum; measured with recommended signal processing and Recommended Protection Filter.

17. Calculated Axial Output Limit: Highest average and peak SPLs possible during the Accelerated Life Test. The Peak SPLrepresents the 2:1 (6 dB) crest factor of the Life Test signal.

18. High Pass Filter: This helps protect the loudspeaker from excessive input signal levels at frequencies below the Operating Range.

GRAPHIC DAT A

1. Resolution:To remove insignificant fine details, 1/12 octave cepstral smoothing was applied to acoustic frequency responses and 1/3 octave cep stral smoothing was applied to the

beamwidth and impedance data. Other graphs are plotted using raw data.

2. Frequency Responses:Variation in acoustic output level with frequency for a constant input signal. Processed: normalized to 0 dB SPL. Unprocessed inputs: 2 V (4 ohm nominal impedance),

2.83 V (8 ohm nominal impedance), or 4 V (16 ohm nominal impedance) referenced to a distance of 1 m.

3. Processor Response:The variation in output level with frequency for a constant input signal of 0.775 V = 0 dB reference.

4. Beamwidth:Average angle for each 1/3 octave frequency band where, starting from the rear of the loudspeaker, the output first reaches -6 dB SPLreferenced to 0 dB SPL as the highest

level. This method means the output may drop below -6 dB SPLwithin the beamwidth angle.

5. Impedance: Variation in impedance magnitude, in ohms, with frequency without regard to voltage/current phase. This means the impedance values may not
be used to calculate True Watt s (see 9 above).

6. Polar Data: Horizontal and vertical polar responses for each 1/3 octave frequency band 100 Hz to 16 kHz or Operating Range.
