AV receiver recommendations
As a rule of thumb, the sine wave (continuous output) power of the AV receiver should roughly correspond to the continuous power handling of the loudspeakers.
An example: A CONSONO 35 loudspeaker has a continuous power handling of 80W - then the AV receiver should also provide this power. A little more (up to max. 110 watts) does not hurt.
