check source signal (is a different audio component fed
by the same source playing correctly?)
Check and increase level adjustment at the source device
Place speaker in front of a wall or in a corner.
Check all connections; reduce the level at ELAC speaker

readjusted.
Check of ELAC speaker for inherent hum: disconnect all

hum, but none at the listening place.
