FEATURES• Two-way, full range loudspeaker• Classic stage monitor design• Pole mount cup (black version only) for use as main system• Large, user-rotatable horn for optimized pattern control• Beamwidth-matching crossover point• Long-lasting reliability
APPLICATIONSBand PA, DJ System, Dance Club, Schools, Houses of Worship, Rental Systems, Mobile Churches, Auditoriums
DESCRIPTIONThe VFM129i two-way, stage monitor loudspeaker system includes a direct-radiating, vented, 12-in LF cone transducer and a 1-in exit / 1.75-in voice coil HF compression driver loaded with a large, square, user-rotatable 90x60 coverage pattern horn.
Because VF Series full range systems (VFR/VFM) use HF sections similar to those developed for the MK Series, EAW engineers could employ the same revolutionary “beamwidth-matching” internal passive crossover/filter networks that set the MK Series apart from all other two-way systems. If powered by an EAW-specified amplifier or via a UX Series digital signal processor, the VFM129i can enjoy the benefits of EAW Focusing, a technology that eliminates the anomalies inherent in the time domain of any loudspeaker.
The VFM129i features a classic stage monitor design with NL4 connectors located on both sides for easy loop-through connections. They also include a pole mount cup should they need to be used as small PA mains. Engineers integrated the handles into the enclosure design, giving the low-profile enclosure a sleek, clean appearance.
Six year warranty.

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.

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.

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.
