Frequency Range: 90Hz-30KHz +/-2dB at 2m on reference axis (-10dB at 47Hz and 40KHz)

Directional Characteristics: Within 2dB of response on reference axis up to 20KHZ for +/-5degrees verticality, up to 20KHz for +/-20degrees horizontally

Maximum Output: 100dB spl on programme peaks under typical listening conditions

Characteristic sensitivity level: 81dB spl at 1m reference axis for pink noise input of 1W

Distortion: Second harmonic: less than 1% from 120Hz to 20KHz. Third harmonic: less than 1% from 70Hz to 20KHz. Measured at 1m on reference axis at mean spl of 90db

Enclosure: 6.7 litres, closed box

Programme rating: 100W

Maximum continuous sinusoidal input: 28V rms, 100-2500Hz, falling to 8V rms from 4000-20,000Hz

Electronic overload protection (S-STOP): The system is protected against any continuous or intermittent fault conditions which produce input signals not greater than 50V peak from DC to 50KHz

Nominal impedance: 8 ohms

Weight: 6.5Kg

Dimensions: 348 x 180 x 197mm (HxWxD)

Pairing of systems guarantees matching of sensitivity and frequency response to within 0.5dB.
