DESCRIPTION

The high output yet incredibly compact SB2001 dual
21-inch cone driver subwoofer is a recommended
companion for all larger format EAW KF Series systems
and will likely find a home in many club environments.
The SB2001 represents a very noteworthy upgrade
to the SB1001/1002 offering in terms of output
capability and low frequency extension (17% larger
voice coils, 59% greater Xmax, and more than double
the volume of air displaced) without much increase in
size. The impressive result is a new and more powerful
workhorse that has greater impact, power handling
and output capability than its celebrated brethren.

Just like the SB1001 the unique driver mounting of
the SB2001 maximizes cone area and allows for the
integration of an extremely low turbulence port while
minimizing frontal area, providing the acoustical
performance and physical configuration well suited for
creating large subwoofer arrays. The enclosure design
additionally integrates sixteen 3/8-16 suspension
points for installation applications and is fully prepped
and ready to receive the user installable quick release
rigging kit accessory for touring applications (coming
soon). The SB2001 is perfectly suited for a wide range
of applications including concert touring, arenas,
large houses of worship, large auditoriums, theaters
and large dance clubs. As always, optimized processor
settings for the UX8800 Digital Signal Processor are
available for download at www.eaw.com

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 Quali cation (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 e ects, 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. SPL is referenced to other distances using the Inverse Square Law.

7. Enclosure Orientation: For beamwidth and polar speci cations, as shown in Mechanical Speci cation drawing.

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

9. 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 de ned
by International Standard.

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

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

12. Operating Mode: User selectable con gurations. Between system elements, a comma (,) = separate ampli er channels; a slash (/) = single ampli er channel. DSP = Digital Signal Processor.
IMPORTANT: To achieve the speci ed per formance, the listed external signal processing must be used with EAW-provided settings.

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

14. Nominal Beamwidth: Design angle for the -6 dB SPL points, referenced to 0 dB SPL as the highest level.

15. 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.

16. 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.

17. Accelerated Life Test: Maximum test input voltage applied with an EIA-426B de ned spectrum; measured with recommended signal processing and Recommended Protection Filter.

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.

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

GRAPHIC DATA

1. Resolution: To remove insigni cant  ne 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. Beamwidth: Average angle for each 1/3 octave frequency band where, starting from the rear of the loudspeaker, the output  rst reaches -6 dB SPL referenced to 0 dB SPL as the highest level. This method
means the output may drop below -6 dB SPL within 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 Watts (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.
