Very powerful speakers for PA applications.   DESCRIPTION A 3-way broadband system in a trapezoidal housing with bass reflex opening. Includes a 38.1 cm(15 inch) low tweeter in a Waveguide hollow with ARCTM technology, a horn-loaded 25.5 cm(10 inch), and a compression driver with 5 cm(2 inches) output, which is coaxialally mounted in the Waveguide cavity on a horn with a constant directional characteristic (60 x 45). The operating mode is switchable: Bi-amping (passive MF/HF frequency pair) or tri-ampling.   APPLICATIONS The real 3-way design of the KF650e Virtual Array system significantly improves the quality of vocal reproduction, while its conus-controlled midrange horn and horn-loaded woofers extend the beam characteristics to the lower octaves   The fields of application include: - Band-PA, - Events in ballrooms - Corporate events - Congress Centres - Big live music clubs   TECHNICAL DATA Deep Sound Subsystem & Loading: 1x 38.1 cm(15 inch) loudspeaker in a waveguide cavity with ARCTM & midrange subsystem Loading: 1x 25,5 cm(10 inch) horn-laden cone tweeter subsystem & Load:1x 5 cm(2-inch) output compression driver on constant directional horn System configuration: 3-way, full range Control configuration(s): Switchable: Bi-amping (passive MF/HF frequency pair) or tri-ampling Controls (switches, controllers): Switches for operation mode Recommended high-pass frequency (24 dB/octave): 45 Hz   Type of housing (form): trapezoidal Housing material: Baltic birch plywood Surface: Black, catalyzed polyurethane Connections: 1 Amphenol AP4 plug and socket each, 1 AP6 plug and jack each   Suspension devices: 3-position flytracks with integrated 0.95cm (3/8)-16 thread Mounting/hanging points (each 3 top and bottom) Grid: vinyl-coated perforated sheet, foam-coated   INVESTMENT VALUES Frequency response (Hz) –3 dB: 65 Hz to 17 kHz, –10 dB: 50 Hz Axial sensitivity (dB SPL/1 Watt/1 m): - Bi-amping MF/HF 107 - AF 100 - Mediumrange 107 - tweeter 107 Impedance (Ohm): - Bi-amping midrange driver / tweeter 8 - bass driver 8 - Midrange 8 - tweeter 8 Load capacity, AES standard (Watt): - midrange driver/ tweeter in bi-amping operation 400 - bass driver 1000 - 400 midrange driver - tweeter 200 Calculated maximum output power (dB SPL, at 1 m): - Bi-Amping mid/ tweeter tip 139,0 - bass driver tip 136,0 - Mediumrange 133.0 - tweeter tip 136,0 - Bi-Amping mid-/ tweeter continuous power 133,0 - bass driver continuous power 130,0 - MF Long-term 133,0 - HF Long-term 130,0 Nominal coverage angle / -6-dB points (degree): - Horizontal 60 - Vertical 45 Dimensions (millimeter): - Height 845 - width (front) 502 - Width (back) 328 - Depth 502 Trapezoidal angle: 10 degrees per side Weight: 63.7 kg Year of construction: end of the 1990s   The speakers are used. They've been tested. Sound came out. Since the correct cables and no suitable amplifier were available, no extensive test could be carried out. They have traces of use such as scratches and abrasions and are dusty due to a longer storage.   The offer includes only the loudspeakers, no other furniture or objects depicted.   Visit possible by arrangement.   Payment: bank transfer only - no cash payment   Shipping not possible. Dispatch and loading is carried out by the acquirer or by a company commissioned by him after consultation.   A delivery of the goods takes place only after receipt of the payment.
