QUAD ESL-2912

摘要

Quad claims 86dB sensitivity for the ESL-2912 'referred to 1m'. Measuring at 1m we recorded a sensitivity of 81.6dB averaged for the review pair, which is within 0.1 dB of the figure we measured from the previous ESL-2905S. Quad's higher figure almost certainly reflects the fact that, because of the large diaphragm area, output from the ESL-2912 will initially decrease less rapidly with distance. Nominal impedance is stated as 8ohm but we measured a minimum modulus of 2.7ohm at 20Hz.
