The tight driver cluster gives the 4401 outstanding coherency in the near field, making it also an excellent choice for a console-mount secondary monitor.The 4401 shares the design philosophy of the larger JBL4430 and 4435 monitors, smooth response over a wide coverage angle, with wide dynamic range and clear, open sound. Particular attention has been paid to the design of the dividing network and to the physical placement of the drivers. Each driver is the product of extensive research and testing, and each has been designed for optimum performance in the system.High Frequency Dome RadiatorTodays recording techniques place a premium on high frequency accuracy and definition, and JBl has designed the 4401s high frequency dome radiator to meet these demands. The dome is formed of a lightweight phenolic material and coated with a microscopiclly thin layer of aluminum through a sophicticated vapor-deposition process. The hard dome construction provides smooth response with higher efficiency and acoustic output than a comparable soft dome. Additionally, the driver exhibits outstandings linearity over its full operating range - there is virtually no power compression. Low Frequemcy DriverThe 4401 utilizes a low frequency driver specially designed for optimum performance in a compact enclosure. The 1700 mm loudspeaker exhibits unusually smooth frequency response, superior transient response, and extremely low distortion. It features a die-cast aluminum frame for structural integrity under the most adverse operating conditions.Symmetrical Field Geometry DesignThe loudspeakers magnetic strukture features JBLs unique Symmetrical Field Geometry (SFG) desin to reduce second harmonic distortion to less than one tenth the level found in conventional designs. The cone is of laminated construction to achieve the desired combination of light weight and rigidity. The coating, and exclusive JBL formulation, adds, a precise amount of mass and provides optimum damping characteristic . Carefully engineered suspension elements reduce DC offsets and an unusually long voice coil allows exceptional excursion linearity.Frequemncy Dividing networkThe sophisticated dividing network contributes significantly to the overall performance of the system. The carefully chosen transition slopes and crossover point provide flat axial response and minimize off-axis variation, so that power response is also smooth. The design allows a more predictable interface of the 4401 qand the studio environment. Stereo imaging also remains stable over a wider area. to take full advantage of the inherently excellent transient response of the two drivers. JBL engineers applied a principle typically found only in active high frequency electronics. Polypropylene and polystyrene bypass capacitors are wired in parallel with the networks larger Mylar capacitors to reduce the hysteresis effects on the signal. This provides improved resolution of complex transient waveforms.The networks iron-core and air-core inductors are carefully chosen for their high current capacity and low DC characteristics. A high frequency level control protrudes through the grille for individual adjustments to the spectral balance.To simplify wall or console mounting, the 4401 may be ordered with optional cradle mounts manufactured of rugged steel.SPECIFICATIONSSystemFrequency Response: 70 Hz to 18 kHz (±3 dB)Power Capacity: 60 WSensitivity: 88 dB SPLNominal Impedance: 8 ?Crossover Frequency: 2,500 HzLow Frequency LoudspeakerNominal Diamater: 170 mm (6-1/2 in)Voice Coil: 38 mm (1-1/2 in)Magnetic Assembly Weight: 1,3 kg (3 lb)Flux Density: 0,95 tesla (9,500 gauss)Sensitivity: 89 dB SPLHigh Frequency Dome radiatorNominal Diameter: 25 mm (1 in)Voice Coil: 25 mm (1 in ) copperMagnetic Assembly Weight: 0,68 kg (1-1/2 lb)Flux Density: 1,4 tesla (14,000 gauss)Sensitivity: 89 dB SPLGeneralFinish: Oiled walnutGrille Color: Dark blueDimensions (W x H x D): 375 x 238 x 183 mmWeight: 16 kg (shipping)Due to the age and because I sell privately, no returns. The warranty expired 40 years ago. For legal reasons, Im selling the device as a hobbyists item, despite its function. Shipping at your own risk. ATTENTION! IMPORTANT HINT!! Due to the new legal provisions, the sale is made without any warranty, guarantee or return. Since this is a private sale, I cannot assume any guarantee under new EU law. The buyer agrees to this and acknowledges this with his purchase! I exclude any liability for material defects. Liability for damages due to injury to health, body or life and grossly negligent and/or intentional breaches of my obligations as a seller remains unrestricted. According to the new EU law, this addition must appear under every online sale, otherwise the seller is also liable as a private person for a whole year for the goods sold! If you have any questions, just ask.

Ersatzlautsprecher der nie eingebaut war.Sicher ist er nur bedingt als neu zu bezeichnen,wennman solche Teile beim Hersteller bestellt liegen sie teilweise auch schon Jahrzehnte im Regal.Deshalb bitte die Bilder von der Sicke genau anschauen und dann bieten.
