DESCRIPTION
The SB products are EAW's premium subwoofers designed for
the most demanding professional applications. Abroad range of
capabilities and sizes provide the designer with selections that
can be specifically matched to their application. Top quality
drivers, engineered by EAW, provide the highest output and best
sonic performance possible for a given form factor. All SB
models are direct radiating, with optimally tuned, vented
enclosures. SB subwoofers are the choice where the best sonic
performance, highest reliability, and most robust physical
construction are required.
The legendary SB1000zR is a high output, large-format
subwoofer system with proven performance in complementing
high efficiency, full-range loudspeakers. It is designed for
portable use where the fatter-sounding output of dual 18 inch
drivers is desired. The SB1000zR's driver mounting maximizes
cone area and minimizes frontal area, providing the acoustical
performance and physical configuration well suited for creating
large subwoofer arrays. Its applications include: concert touring,
arenas, band/club PA, large houses of worship, large
auditoriums/theaters, stage/performer monitoring, drum fill
monitoring, and large dance clubs.
The SB1000zR is designed to be used with today's sophisticated
digital signal processing to optimize the LF response. EAW's MX
Series processors are recommended for the required crossover
and equalization.
Six Year Warranty.

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 SPL of 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 SPL points, referenced to 0 dB SPLas the highest level.
14. Axial Sensitivity: Power averaged SPL over 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 SPL represents 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),
2.83 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. 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).
