Pair of speakers, they work, however a review is recommended before enjoying its excellent sound.
Lower cut-off frequency, -3 dB: < 32 Hz
Upper cut-off frequency, -3 dB: > 20 kHz
Free field frequency response tolerance of system ± 3 dB
Maximum continuous sine wave acoustic output @ 1m on axis in half space > 116 dB
Maximum continuous RMS acoustic output in same conditions with IEC-weighted noise: > 116 dB
Maximum peak acoustic output per pair at engineers’ site, speakers @ 2 m from the engineer, with
music material > 122 dB
A -20 dBu signal input will produce 97 dB SPL in free field @1 m on axis with all controls set at the ‘CAL’ position.
The CAL position is the 0 dB position of all tone controls and the maximum sensitivity position of the input level control.
See specification in the Crossover Section
Self generated noise level in free field @ 1m on axis < 15 dB (A weighted)
Harmonic distortion at 100 dB SPL @ 1m on axis
f < 200 Hz < 3 %
f > 200 Hz< 1 %
