| 39Hz LF Limit, High Power handling, High Efficiency |
| Low distortion, Low thermal compression |
| Laminar vents |
| Integrated locking feet |
| Designed with Cardioid Sub Arrays in mind |
OVERVIEW
The SB112i is a high efficiency, high impact sub-bass loudspeaker with exceptionally high power handling. It provides high impact, high sensitivity, low thermal compression and incredibly low distortion, even at the highest drive levels. These combined properties deliver the sonic qualities of precision and musicality.
The SB112i 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 SB112i can be deployed in standard or cardioid configurations, with dedicated presets for each configuration, in flown, or stacked configurations.
The SB112i features one long excursion, high power handling 12” cone loudspeaker 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 44 Hz to 120 Hz when flown and from 39 Hz to 100 Hz when used as a general ground support subwoofer.
The SB112i enclosure was designed with installation in mind. It features 16 integrated fly points and optional array frames that allow for mounting to ceilings and the creation of traditional and cardioid flown arrays. The compact profile allows the SB112i 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. Components in the front of the enclosure are protected by a steel grill made from perforated steel and lined with acoustically transparent foam. All grill and 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 Linea Research C and M series amplifiers, with proprietary presets provided by RMS-Acoustics.
