This compression tweeter is designed for use in multi-element loudspeaker systems in sound reinforcement applications that require high output, narrow controlled dispersion and long throw. This model produces a very high output level with flat response and excellent transient attack. This unit features an aluminium voice coil diaphragm assembly, which is field replaceable without soldering. * Nominal impedance: 8 Ohm * Minimum impedance: 7.9 ohm * Sensitivity: 107 dB 1 W @ 1 m * Re: 6.3 ohm * Frequency range: 5000-20000 Hz * Power capacity: 25 W AES * Program power: 50 W * Recom. crossover frequency: 5 kHz or higher (12 dB/oct. min slope) * Dispersion HxV: 40 Degrees conical * Voice coil diameter: 38.1 mm 1.5 in * Flux density: 1.55 T * BL factor: 5.2 N/A * Diaphragm material: Aluminium
