DESCRIPTION
The UB22z is engineered for extra-wide-angled coverage
(horizontal) from a wall mounted position. This ultra-compact
loudspeaker provides surprisingly high output and exceptional
fidelity for near field applications. It is highly effective as a fill/delay
element in larger overall systems or for foreground/background
music reproduction as a stand-alone loudspeaker or in distributed
systems.

Because they are compact and lightweight, UB22zs install quickly
and easily in difficult spaces. As components of larger overall
systems, the UB22z series can be used to provide underbalcony,
overbalcony, and side box area coverage. Applications as fill/delay
elements include large and small theatres and houses of worship.As
a main system, they can be built into high definition, distributed
systems for use in industrial or retail environments and as
standalone or distributed loudspeakers for boardrooms, restaurants,
offices, and transportation centers.
Foam-backed grilles hide the drivers from view for pleasing
aesthetics. Side mounting points allow enclosures to be mounted in
using accessory brackets. Additional mounting points accept an
OmniMount® 30.0 Series or similar bracket. Standard colors are
black and white. Other colors can be specified as a special order
items.
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. Enclosure Orientation: For beamwidth and polar specifications, as shown in Mechanical Specification 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 defined 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 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.
13. 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.
14. Nominal Beamwidth: Design angle for the -6 dB SPLpoints, referenced to 0 dB SPLas the highest level.
15. 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.
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 defined spectrum; measured with recommended signal processing and Recommended Protection Filter.
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.
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 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. 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 SPLas 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 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.
