Vintage JBL 2402H Horn Bullet Tweeter, 8 ohm. - UNTESTED - Professional Series Key Features: c 40 W continuous program c 2.5 - 15 kHz response c 44 mm (13?4 in) aluminum ribbon voice coil c 110 dB sensitivity, 1 W, 1 m c 40° conical dispersion at 10 kHz Sound reinforcement applications demand loudspeakers with high acoustic output and controlled disper- sion. The JBL Model 2402H ultra-high frequency transducer is engineered to meet these demands, providing tight pattern control, deep penetration, and extremely high on-axis sensitivity. The high end of the audio spectrum is reproduced with incredible clarity and crispness – all the realism a performer could desire. Frequency response extends smoothly from 2.5 kHz to 15 kHz. A circular exponential horn assembly provides a dispersion pattern that is 40° conical at 10 kHz. For a given power input, the 2402H produces an exceptionally high acoustic output, converting a 10 W input into a sound pressure level of 100 dB at a distance of 10 m (33 ft). Such efficiency allows the 2402H to re-create intense high frequency onsets and transients with outstanding clarity and accuracy. The 2402H utilizes an anisotropic strontium ferrite magnet, manufac- tured using a wet-pressed forming process. The benefits of this technol- ogy are better temperature stability, resistance to demagnetization, reduc- tion in weight over typical ferrite material, and the highest performance on an actual production basis. A flux density of 1.75 T (17,500 gauss) in the voice coil gap is realized. Specifications: Horn Mouth Diameter: 79 mm (31?8 in) Nominal Impedance: 8 ohms Minimum Impedance: 8 ohms at 2.5kHz DC Resistance: 6.25 ohms ±10%@25°C Power capacity: 40 W continuous program Sensitivity : 110 dB, 1 W, 1 M (3.3 ft) Frequency Response (±3 dB): 3 kHz to 15 kHz Frequency Range (–10 dB): 2.5 kHz to 15 kHz Dispersion: 40° conical at 10 kHz Recommended Crossover: 2.5 kHz or higher Diaphragm: 0.056 mm (0.0022 in) aluminum alloy Voice Coil Diameter: 44 mm (13?4 in) Voice Coil Material: Aluminum ribbon Magnetic Assembly Weight: 1.9 kg (41?8 lb) Flux Density: 1.75 T (17,500 gauss) Baffle Cutout Diameter: 79 mm (31?8 in) Dimensions: 121 mm diameter (43?4 in) 98 mm depth (37?8 in) 1Continuous program is defined as 3 dB greater than continuous pink noise and is a conservative expression of the transducer’s ability to handle normal speech and music program material. Continuous pink noise power ratings are tested with pink noise input having a 6 dB crest factor, with a high-pass filter set at the specified lower limiting frequency for two hours duration. 2Averaged from 5 kHz to 20 kHz. The circular exponential horn assembly is die cast of solid aluminum. Internally, the annular diaphragm is pneumatically formed of fatigue-resistant aluminum alloy. Wire used in the 44 mm (13?4 in) voice coil is aluminum, milled to a thin ribbon. This process places a maximum amount of conductor in the magnetic gap for optimum efficiency and transient response. The use of high-temperature voice-coil former materials and adhesives has improved the power handling and rug- gedness of the drivers. Architectural Specifications: The transducer shall have a measured sensitivity (SPL at 1 m with a 1 W input swept from 5 kHz – 20 kHz) of at least 110 dB on axis. On- axis frequency response measured under free-field conditions at a distance of 1.8 m (6 ft) or more shall extend from 3 kHz to 15 kHz, within plus or minus 3 dB. Dispersion shall be 40° conical at 10 kHz, when measured at 6 dB down points relative to on-axis frequency response charactistics using 1?3-octave band pink noise as the signal source. Nominal impedance shall be 8 V and the power capacity shall be at least 20 W when driven by pink noise, band-limited from 6 kHz to 20 kHz. The transducer shall have a maximum diameter of 121 mm (43?4 in), a depth of 98 mm (37?8 in) and weigh not less than 2.3 kg (5 lb). The exponential horn shall be die cast of aluminum and the magne- tic circuit shall weigh not less than 1.9 kg (41?8 lb). Voice coil diameter shall be 44 mm (13?4 in) operating in a magnetic field whose flux density measures at least 1.75 T (17,500 gauss). Voice coil wire shall be milled aluminum ribbon. The transducer shall be JBL Model 2402H. Multimeter not included Sold as Preowned vintage ,,,,ebay charges & collects the tax not me.
