FEATURES• High output sub bass system• Dual 15-in cone transducers• Optimally vented for increased response• Extended pole mount cup creates stable base• Easy lift handles (Black version only)

DESCRIPTIONThe VFS “i” revision brings the VF concept more fully into the EAW product line. VFS “i” Series black versions use handles from the KF and JF Series. An installation only white version comes without handles or a pole mount cup.

The VFS250i sub bass system includes dual, direct radiating 15-in LF cone transducers mounted in an optimally vented enclosure. Enclosure venting uses the enclosure’s resonance to enhance LF response while limiting driver wear.

The VFS250i black version includes traditional portable features such as a pole-mount cup, parallel NL4 4-terminal connectors, barrier strip inputs, and handles that accept accessory covers for permanent installation. The white, installation-only versions omit handles and the pole-mount cup but include NL4 connectors, barrier strip inputs, and multiple mounting points. The new design leaves the enclosure sides completely smooth and attractive. Optional rigging hardware is available for preconfigured arrays of VFR and VFS systems.

Six year warranty.

NOTESTABULAR 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,resolutionthelargerof1.5Hzor1/48octave;Time:accuracy+/-10.4μs,precision+/-0.5μs,resolution10.4μs;Angular:accuracy+/-1°,precision+/-0.5°,resolution0.5°. 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. SPL is referenced to other distances using the Inverse Square Law. 7. Enclosure Orientation:Forbeamwidthandpolarspecifications,asshowninMechanicalSpecificationdrawing. 8. Volts: Measured rms value of the test signal. 9. Watts:Peraudioindustrypractice,“loudspeakerwatts”arecalculatedasvoltagesquareddividedbyratednominalimpedance.Thus,thesearenotTrueWattunitsofenergyasdefined 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:Userselectableconfigurations.Betweensystemelements,acomma(,)=separateamplifierchannels;aslash(/)=singleamplifierchannel.DSP=DigitalSignalProcessor. IMPORTANT:Toachievethespecifiedperformance,thelistedexternalsignalprocessingmustbeusedwithEAW-providedsettings. 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:MaximumtestinputvoltageappliedwithanEIA-426Bdefinedspectrum;measuredwithrecommendedsignalprocessingandRecommendedProtectionFilter. 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:Toremoveinsignificantfinedetails,1/12octavecepstralsmoothingwasappliedtoacousticfrequencyresponsesand1/3octavecepstralsmoothingwasappliedtothebeamwidthand 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:Averageangleforeach1/3octavefrequencybandwhere,startingfromtherearoftheloudspeaker,theoutputfirstreaches-6dBSPLreferencedto0dBSPLasthehighestlevel.Thismethod 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.
