The VFR9i two-way, full range loudspeaker system includes a direct-radiating, vented, -in LF cone transducer and a -in exit /.75-in voice coil HF compression driver loaded with a large, square, user-rotatable 90x60 or 60x5 coverage pattern horn built on the classic MK Series horns. These horns deliver exceptional high frequency dispersion, and their square shape lets users rotate the enclosure around the horn to maintain directivity in a horizontal configuration. The standard horn is field replaceable with an optional 60x5 horn. This change incorporates a passive filter adjustment to maintain consistent acoustic response and smooth beamwidth throughout the crossover region. ecause VF Series full range systems (VFR/VFM) use HF sections similar to those developed for the MK Series, EW 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 EW-specified amplifier or via a UX Series digital signal processor, the VFR9i can enjoy the benefits of EW Focusing, a technology that eliminates the anomalies inherent in the time domain of any loudspeaker. The VFR9i black version includes traditional portable features such as a pole-mount cup, parallel NL -terminal connector, barrier strip connector, an optional transformer and handles that accept accessory covers for permanent installation. The white, installation-only versions omit handles and the pole-mount cup but include NL connector, barrier strip connector, an optional transformer, and multiple mounting points. The new design leaves the enclosure sides completely smooth and attractive. Optional rigging hardware is available for preconfigured arrays with VFS sub bass systems. Six year warranty.

Measurement/Data Processing Systems: Primary - Fhart: proprietary EW software; Secondary - rüel & Kjær 0.. Microphone Systems: Earthworks M0; rüel & Kjær. Measurements: Dual channel FFT; length: 768 samples; sample rate: 8 khz; logarithmic sine wave sweep.. Measurement System Qualification (includes all uncertainties): SPL: accuracy +/-0. khz, precision +/-0.5 d 0 Hz to 0 khz, resolution 0.05 d; Frequency: accuracy +/- %, precision +/-0. Hz, resolution the larger of.5 Hz or /8 octave; Time: accuracy +/-0. μs, precision +/-0.5 μs, resolution 0. μs; ngular: accuracy +/-, precision +/-0.5, resolution 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: 7.6 m. coustic responses represent complex summation of the subsystems at 0 m. SPL is referenced to other distances using the Inverse Square Law. 7. Enclosure Orientation: For beamwidth and polar specifications, as shown in Mechanical Specification 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 defined by International Standard. 0. SPL: (Sound Pressure Level) Equivalent to the average level of a signal referenced to 0 d SPL = 0 micropascals.. Subsystem: This lists the transducer(s) and their acoustic loading for each passband. Sub = Subwoofer, LF = Low Frequency, MF = Mid Frequency, HF = High Frequency.. Operating Mode: User selectable configurations. etween system elements, a comma (,) = separate amplifier channels; a slash (/) = single amplifier channel. DSP = Digital Signal Processor. IMPORTNT: To achieve the specified performance, the listed external signal processing must be used with EW-provided settings.. Operating Range: Range where the processed Frequency Response stays within -0 d SPL of the power averaged SPL within this range; measured on the geometric axis. Narrow band dips are excepted.. Nominal eamwidth: Design angle for the -6 d SPL points, referenced to 0 d SPL as the highest level. 5. xial Sensitivity: Power averaged SPL over the Operating Range with an input voltage that would produce W at the nominal impedance; measured with no external processing on the geometric axis, referenced to m. 6. Nominal Impedance: Selected, 8, or 6 ohm resistance such that the minimum impedance point is no more than 0% below this resistance over the Operating Range. 7. ccelerated Life Test: Maximum test input voltage applied with an EI-6 defined spectrum; measured with recommended signal processing and Recommended Protection Filter. 8. alculated xial Output Limit: Highest average and peak SPLs possible during the ccelerated Life Test. The Peak SPL represents the : (6 d) crest factor of the Life Test signal. 9. High Pass Filter: This helps protect the loudspeaker from excessive input signal levels at frequencies below the Operating Range. GRPHI DT. Resolution: To remove insignificant fine details, / octave cepstral smoothing was applied to acoustic frequency responses and / octave cepstral smoothing was applied to the beamwidth and impedance data. Other graphs are plotted using raw data.. Frequency Responses: Variation in acoustic output level with frequency for a constant input signal. Processed: normalized to 0 d SPL. Unprocessed inputs: V ( ohm nominal impedance),.8 V (8 ohm nominal impedance), or V (6 ohm nominal impedance) referenced to a distance of m.. Processor Response: The variation in output level with frequency for a constant input signal of V = 0 d reference.. eamwidth: verage angle for each / octave frequency band where, starting from the rear of the loudspeaker, the output first reaches -6 d SPL referenced to 0 d SPL as the highest level. This method means the output may drop below -6 d 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 / octave frequency band 00 Hz to 6 khz or Operating Range.
