DESCRIPTION  
EAW SB subwoofers are premium products designed for the most  
demanding professional applications. A broad range of capabilities  
and sizes provide designers with selections that can be specifically  
matched to the application. Top quality drivers, engineered by EAW,  
supply 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 absolute best sonic performance, highest reliability, and most  
robust physical construction are required.

The SB1002 is a large-format, high-output subwoofer system  
that can be ground-stacked or easily flown via an integral rigging  
system, making it ideal for a wide range of live and installed sound  
applications.Itoffersthefatter-soundingoutputofdual18-inchcone  
drivers, with the mounting of these drivers maximizing cone area  
and minimizing front area, providing the acoustical performance  
and physical configuration well suited for creating large subwoofer  
arrays.ThedriversaredesignedspecificallyfortheSB1002,offering  
very large (4.5-inch) voice coils as well as powerful neodymium  
magnet structures that also reduce weight.

The SB1002 is designed to be used with sophisticated digital signal  
processing to optimize the LF response. EAW UX and MX Series  
processors are recommended for the required crossover and  
equalization.  
The rigging system, similar to that of EAW’s popular KF760 Series  
line arrays, features a fast, easy-to-use two-point approach that  
accommodates flown arrays of up to 12 SB1002 units. A handle  
on the rear upper corner of the SB1002 enclosure provides added  
guidance and convenient “push-pull” ability in the flying process.  
Applications include large live music and dance clubs, houses  
of worship, performing arts/auditoriums, corporate events, and  
concert touring.  
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-windowed 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. CalculatedAxial Output Limit: Highest average and peak SPLs possible during theAccelerated 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),  
2.83 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).
