Yes, you have read the measurement results from our lab correctly (in case you checked them): For 94 decibels of sound pressure at a distance of one meter, this speaker needs just 0.07 Watts of power. Seven Watts would be somewhat normal, 0.7 Watts already a sensation – but 0.07 Watts reads like a typo. It is completely true though! This is made possible by the large horn at the top end of the Duo XD, coming from the specialist Avantgarde Acoustic, based in a small town in the Odenwald mountain range in southwestern Germany. This horn is connected directly to the amplifier without any intermediate crossover and visually symbolizes the phenomenal efficiency with its huge opening of 67 centimeters.
