Not for the faint of heart, the newest DXS XLF’s go deeper than any model before, with an extended low frequency of 30Hz— perfect for professional touring musicians, DJ’s, and sound engineers who need that extra-low, thundering bottom end that you just can’t get from other subwoofers in this class. Flexible DSP and a bass-reflex cabinet design with a wide, flared port ensure your lower frequencies maintain outstanding clarity and musicality even when the volume is cranked.
