No crossover network is required. The excellent transient response provides a pure and clean sound with very low harmonic distortion. Improve the stability of your amplifier by connecting a 33 ohm / 10W resistor in series with the tweeter.
■ impedance: 4-8 ohm
■ nominal power: 75W
■ maximum power: 150W
■ frequency response: 1.2-23kHz
■ sensitivity: 90dB
