NOTES

TABULAR DATA

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: To achieve the specified performance, the listed external signal processing must be used with EAW-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.High Pass Filter: This helps protect the loudspeaker from excessive input signal levels at frequencies below the Operating Range.

17.Accelerated Life Test: System: Maximum test input voltage applied with an EIA-426B defined spectrum; measured with specified signal processing; Transducer: AES2-1984 R 1997.

18.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.

GRAPHIC DATA

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

2.83V (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.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 Watts (see 8 above).
