The SB15m is the recommended subwoofer for the KIVA system and the XT coaxial series. It allows extending the system operating frequency range down to 40 Hz.The SB15m features one direct radiating 15" speaker in a bass reflex tuned enclosure.

The cabinet is made of first grade Baltic birch plywood to ensure maximum acoustical and mechanical integrity.

SB15m subwoofers can be flown or ground stacked as a standalone array or within a vertical SB15m/KIVA array. A pole-mount socket is integrated into the cabinet, for the mounting of one XT enclosure or two KIVA enclosures.

The SB15m is driven and amplified by the LA4 or the LA8 controller. These ensure linearisation, protection and optimisation for the loudspeaker system in its different configurations including cardioid.
