One large MF/HF horn fills the entire face of the enclosure, better  
maintaining horizontal pattern control throughout the MF/HF  
passband. The curved aperture MF loading slots effectively  
move the MF acoustic origin further into the horn than physical  
space permits. The side-mounted LF drivers provide a forward-  
firing, figure eight type pattern. The drivers are spaced so that  
the LF beamwidth matches the MF through crossover.  
The KF730P input features barrier strip terminals. A separate  
terminal strip is provided for loop-through connection for daisy-  
chaining additional KF730Ps. The KF730P is configured using  
the included KF730P Splay Angle Brackets to bolt the  
enclosures together. This rigging system is fully compatible with  
the companion SB730P subwoofer. Six year warranty.  
1 To achieve specified performance, the listed external signal processing with EAW-provided settings is required.

NOTES  
TABULAR DATA  
1. Primary Measurement/Data Processing System: FChart: proprietary EAW software.  
2. Secondary Measurement System: Brüel & Kjær 2012.  
3. Microphone Systems: Earthworks M30; Brüel & Kjær 4133  
4. Measurements: Dual channel FFT; length: 32 768 samples; sample rate: 48 kHz; logarithmic sine wave sweep.  
5. 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 +/-1°, resolution 1°.  
6. Environment: Measurements time-windowed and processed to eliminate room effects, approximating an anechoic environment. Data processed as anechoic or fractional space, as noted.  
7. Measurement Distance: 7.6 to 8.0 m. Data is referenced to other distances using the Inverse Square Law.  
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 Bass = 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. Peak Sensitivity: Highest axial SPLmeasured within the 20 Hz to 20 kHz bandpass 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.  
17. 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.  
18. Accelerated Life Test: Maximum test input voltage applied with an EIA-426B defined spectrum; measured with recommended signal processing and Recommended Protection Filter.  
19. 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.  
20. Recommended High Pass Filter: This should be used to help protect the loudspeaker from excessive input signal levels below the Operating Range.  
GRAPHIC DATA  
1. Resolution: To remove insignificant fine details, 1/12 octave cepstral smoothing was applied to acoustic frequency response and 1/3 octave cepstral smoothing was applied to the  
beamwidth and impedance data. Other graphs are plotted using raw data.  
2. Frequency Responses: The variation in acoustic output level with frequency for a constant input signal of 2 volts (4 ohm nominal impedance), 2.83 volts (8 ohm nominal impedance),  
or 4 volts (16 ohm nominal impedance) referenced to a distance of 1 m. For processed systems, this applies where the processor gain is 0 dB in the Processor Frequency Response graph.  
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. Referenced to 20 m.  
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).
