The SB212i-LO is an ultra low profile, high efficiency, high impact sub-bass loudspeaker with exceptionally high power handling. This incredibly capable sub is ideally used when an excellent sub performance is required, yes space constraints are tight. It provides high impact, high sensitivity, low thermal compression and incredibly low distortion out of a compact package, even at the highest drive levels. These combined properties deliver the characteristic RMS-Acoustics sonic qualities of Impact, precision, and musicality.
The SB212i-LO is one of the recommended subwoofers for use with the C coaxial series and is also well suited for use with the VC system family from RMS-Acoustics. The SB212i-LO can be deployed in standard or cardioid configurations, with dedicated presets for each configuration, in flown, or stacked configurations.
The SB212i-LO features two long excursion, high power handling 12” cone loudspeakers mounted in a mechanically and acoustically optimized bass reflex cabinet with laminar venting. Port turbulence is virtually eliminated, and high drive level distortion is minimized via large, flared, symmetrical laminar venting. It operates from 29 Hz to 100 Hz when used as a general ground support subwoofer.
The SB212i-LO enclosure was designed with installation in mind. The compact ultra low profile allows the SB212i-LO to fit easily under stages, up tight to ceilings, and between standard framing for flush mount installations.
The enclosure is constructed of premium birch hardwood plywood to ensure maximum acoustical and mechanical integrity. It is then coated with a weather and wear resistant textured urethane hybrid finish. Optional rigging components are weather and corrosion protected with a heat cured epoxy powder coated finish or zinc plating with passivation.
The optimum processed loudspeaker solution for the RMS-Acoustics SB subwoofer family are RMS-ACOUSTICS series of processed amplifiers. Additionally, the Linea Research C and M series amplifiers, with proprietary presets provided by RMS-ACOUSTICS are supported.
