Includes a 12-in woofer, a horn-loaded 7-in midrange cone and a 1-in exit compression driver on a 90 x 45 constant directivity horn. Powering mode is switchable: passive (3- way crossover) or biamplified (passive MF/HF crossover). APPLICATIONS The KF300e adapts Virtual Array Technology to a compact arrayable enclosure. 3-way design dramatically improves the quality of vocal reproduction while the cone-driven midrange horn extends pattern control into the lower octaves. It pro- vides high output, high definition coverage for permanent or portable applications. Universal suspension hardware fea- tures a flytrack with integral 3/8"-16 mounting/suspension points. Six year warranty. Applications include: Band PA Ballroom Events Corporate Events Convention Centers Small HOW’s Live Music Club DESCRIPTIVE DATA Part Number 999012 Product Group S LF Subsystem & Loading 1x 12-in, Vented MF Subsystem & Loading 1x 7-in Horn-Loaded Cone HF Subsystem & Loading 1x 1-in Exit Compression Driver on Constant Directivity Horn System Configuration 3-way, Full Range Powering Configuration(s) Switchable: Full Range (passive LF/HF crossover) or Biamplified Controls (switches, knobs) Powering Mode Switch Recommended High-Pass Frequency (24 dB/Octave) 50Hz Cabinet Type (shape) Trapezoidal Enclosure Materials Baltic Birch Plywood Finish Black Catalyzed Polyurethane Connectors 2x Neutrik NL4 Speakon 1 each male and female AP4 Suspension Hardware (6) 3-Position Flytracks with integral 3/8”-16 Threaded Mounting/Suspension Point (3 each top & bottom), (4) 3/8”-16 Threaded Mounting/Suspension points (2 per side), Recessed Cup for Standmount Grill Foam Backed Vinyl Coated Perforated Steel Options 179001 Flyclip with ring 179002 Flyclip with hook NOMINAL DATA Frequency Response (Hz) ±3 db 70Hz to 20kHz -10 dB 50Hz Axial Sensitivity (dB SPL/1 Watt/1m) Full Range 99 Biamped MF/HF 104 Biamped LF 99 Impedance (Ohms) Full Range 6 Biamped MF/HF 6 Biamped LF 6 Power Handling, AES Standard (Watts) Full Range Passive 500 Biamped MF/HF 300 Biamped LF 600 Calculated Maximum Output (dB SPL, @ 1m) Full Range Peak 132.0 Biamped MF/HF Peak 134.8 Biamped LF Peak 132.8 Full Range Long Term 126.0 Biamped MF/HF Long Term 128.8 Biamped LF Long Term 126.8 Nominal Coverage Angle / -6 dB points (degrees) Horizontal 90 Vertical 45 Recommended Complementary Systems Sub SB330e Dimensions inches millimeters Height 27.5 699 Width (Front) 14.75 375 Width (Rear) 9.63 245 Depth 14.75 375 Trapezoid Angle 10 degrees per side Weights pounds kilograms Net Weight 95 43.2 Shipping Weight 103 46.9

The LF driver shall be mounted in a vented enclosure tuned for optimum low frequency response. The MF driver shall be loaded into a midrange horn constructed of 3mm birch ply- wood reinforced with high density polyurethane foam. The MF horn shall incorporate a phase/displacement plug. The HF driver shall be loaded on constant directivity horn with a nominal coverage pattern of 90° (h) x 40° (v). An internal passive filter network shall provide fourth order acoustical crossover and system equalization. System frequency response shall vary no more than ±3 dB from 70 Hz to 20 kHz measured on axis. In passive mode, the loudspeaker shall produce a Sound Pressure Level (SPL) of 99 dB SPL on axis at 1 meter with a power input of 1 Watt, and shall be capable of producing a peak output of 132 SPL on axis at 1 meter. It shall handle 500 Watts of amplifier power (AES Standard) and shall have a nominal impedance of 6 Ohms. In biamped mode, the low frequency section produce a Sound Pressure Level (SPL) of 99 dB SPL on axis at 1 meter with a power input of 1 Watt, and shall be capable of producing a peak output of 132.8 SPL on axis at 1 meter. It shall handle 600 Watts of amplifier power (AES Standard) and shall have a nominal impedance of 6 Ohms. In addition, the mid/high section in biamped mode shall produce a Sound Pressure Level (SPL) of 104 dB SPL on axis at 1 meter with a power input of 1 Watt, and shall be capable of producing a peak output of 134.8 SPL on axis at 1 meter. The mid/high sec- tion in biamped mode shall handle 300 Watts of amplifier power (AES Standard) and shall have a nominal impedance of 6 Ohms. The loudspeaker enclosure shall be trapezoidal in shape. It shall be constructed of 15mm thickness void-free cross-grain- laminated Baltic birch plywood and shall employ extensive internal bracing. It shall be finished in black catalyzed poly- urethane. Input connectors shall be dual Neutrik NL4 Speakon plus one each male and female AP4. The system shall in- clude a switch allowing it to be operated in biamp or passive powering mode. A total of six 3-position flytracks with inte- gral 3/8"-16 threaded mounting/suspension points (3 each top and bottom) plus 4x 3/8"-16 threaded mounting/sus- pension points (2 per side) shall be provided. The front of the loudspeaker shall be covered with a vinyl coated perfo- rated steel grill backed with open cell foam to protect against dust. The three-way full range loudspeaker shall be the EAW model KF300e. 8.75 BACK VIEW A-A TYP BOTH SIDES SAME ON TOP AND BOTTOM TOP 20° 2.89 14.75 27.50 9.81 9.00 14.75 A A 7.04 4.85 3.63 2.00 2.00 SIDE 3.88 3.06 5.56 7.00 FRONT BOTTOM TOP HAT SOCKET FOR POLE MOUNT FLY TRACK MOUNT, 3 POSITION.
