L’Acoustics SB18M Subwoofer New Color Code (Ral: 8019) in good condition Incl. covers.
The SB18m is the recommended subwoofer for the ARCS® WIDE and ARCS® FOCUS line sources, and other L-ACOUSTICS® mobile systems. It allows extending the operating frequency range of the system down to 32Hz.
The SB18m features one 18” speaker in a dual bass-reflex tuned enclosure. It provides impact, sensitivity, low thermal compression and reduced distortion. One of the vents features a progressive profile allowing laminar airflow and reduced turbulence noise, even at the highest operating levels. These combined properties contribute to the sonic qualities of the SB18m in terms of precision and musicality. The cabinet is made of first grade Baltic birch plywood to ensure maximum acoustical and mechanical integrity.
SB18m subwoofers can be flown or ground-stacked, as a standalone array or within a vertical SB18m/ARCS® WIDE or SB18m/ARCS® FOCUS array. A polemount socket is integrated into the cabinet, for the mounting of one XT, two KIVA, one ARCS® WIDE or one ARCS® FOCUS.
The SB18m is driven and amplified by either the LA4 or LA8 controller. These ones
ensure linearization, protection and optimization for the loudspeaker system in its different operating modes, cardioid included.
