VC115Si — RMS Acoustics

OVERVIEW

The RMS-Acoustics VC115Si is a compact, high output subwoofer designed to extend the low frequency bandwidth of the variable curvature (VC) family of products. The VC115Si is the recommended subwoofer for the VC system and well suited for use with the coaxial C series from RMS-Acoustics. Combinations of VC10 curvilinear source modules can be flown or stacked with VC115Si subwoofers via the integrated rigging plates. The VC115Si can be deployed in standard or cardioid configurations, with dedicated presets for each configuration, in flown, or stacked configurations.

VC115Si features one high excursion, direct radiating 15‘‘ transducer mounted in a bass-reflex tuned enclosure. It operates from 40 Hz to 100 Hz when associated with VC10 and from 38 Hz to 90 Hz when used as a general ground support subwoofer. The cabinet is made of premium exterior grade Baltic birch plywood to ensure maximum acoustical and mechanical integrity. The VC15S features laminar vents that significantly reduce turbulence and port noise at high drive levels.

The VC115Si subwoofer 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 optimum processed loudspeaker solution for the RMS-Acoustics VC Family are Linea Research C and M series amplifiers, with proprietary presets provided by RMS-Acoustics.
