Description
From corporate events to festivals, every aspect of Redline has been
targeted at making life easier for the live sound professional. From
transducers and electronics to enclosure design and tments, Redline is
built to live in the working world of demanding clients, tight schedules
and even tighter budgets.
The RL18S includes a complete on-board 1,000-watt electronics package
mated to a highly-customized precision transducer engineered to meet
the specic demands of the Redline family. In addition to signature EAW
acoustical design, DynO™ algorithms optimize the power transfer from
ampliers to transducers
for improved headroom and integrity of sound
at maximum output
. Push-button cardioid functionality (using two or
more RL18S subwoofers) keeps low-frequency energy o the stage and
on the audience, and a rear-panel LED mute keeps Redline invisible in
aesthetically-sensitive situations.
The RL18S enclosure incorporates EAW’s signature SB rear angle to
minimize input panel visibility in cardioid mode, integral road glove-
ready wood handles and sleek but strong sculpted grilles on RoadCoat™
enclosures.
Six year warranty on enclosure. Two year warranty on electronics.

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 Qualication (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 eects, 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 specications, as shown in Mechanical Specication 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 dened 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 congurations. Between system elements, a comma (,) = separate amplier channels; a slash (/) = single amplier channel. DSP = Digital Signal Processor.
IMPORTANT: To achieve the specied 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 dened 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 insignicant 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.
