Sony’s Extra Bass Speaker range adds color to your life with its powerful sound. The new products in the series include the SRS-XB12, SRS-XB22 and SRS-XB32 portable speakers, as well as the new high-power speaker GTK-XB72. Despite their compact size, the XB22 and XB32 feature dual passive radiators that work together with stereo full-area speakers to empower the bass sound and enhance low-frequency sounds. The XB12, on the other hand, uses a single passive radiator to create a similar effect.
