DESCRIPTION

The MicroWedge MW15 is a collaboration between original
MicroWedge Series inventor Dave “Rat” Levine (owner of Rat Sound
Systems, Inc.) and the EAW Engineering Department, resulting in
dramatically upgraded performance and ergonomics. A 15 inch woofer
is paired with a 3 inch voice coil HF compression driver on a horn that
provides full yet controlled 90 degree horizontal dispersion.
All frequencies emanate from the exact same point, eliminating
crossover region problems and time/phase irregularities, as well as
optimizing coherency. The coaxial approach also contributes to a very
compact, low-profile footprint.

MicroWedge MW15 monitors are processor enhanced (rather than
processor dependant) for true “plug and play” operation. User
selectable single-amp and bi-amp modes are provided. The large port
on the front of the cabinet enhances LF response in coupling with the
floor, and this port houses both the carrying handle and the passive/
active mode switch. The port also contains dual input connectors,
keeping them concealed and protected, and allowing wedges to be
placed as close together as desired. Additional cable can be stored in
the port without impacting LF performance.

Rubber feet on the bottom of the enclosure reduce abrasion, and new
integral rigging hardware – also mounted on the enclosure bottom –
facilitates easy flying. The Baltic birch cabinets are protected with
EAW’s RoadCoat™ finish that’s extremely durable, and the rugged
steel grille keeps its distinctive shape even when stood upon. All
components are highly liquid tolerant – virtually impervious to spilled
drinks as well as natural elements like rain.

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 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 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.
