The SW 1000 Be subwoofer is the redesigned version of the Electra Be subwoofer to ensure compatibility with the other loudspeakers in the Sopra line.
It is equipped with a 13" (33cm) "W" cone speaker driver (high rigidity for no distortion, even at high volumes), a high-power 600 W RMS BASH® amplifier and a front laminar port (no dynamic bass compression).
