Tannoy has introduced the first Active Ceiling Mounted Subwoofer, engineered to render extended, low frequency reinforcement and impact from a concealed position in installations such as retail outlets, theme pubs and clubs. The CMS110B has been designed to fit unobtrusively into a 2ft x 2ft ceiling tile opening and utilises standard air-conditioning covers in place of speaker grilles for additional concealment.Featuring an adjustable low and high frequency filter and EQ boost, the CMS110B also possesses phase and earth lift switching, in addition to gain control. Furthermore, the speaker's long excursion 10" bass transducer is powered by a 110W amplifier with compressor limiting overload protection and fully balanced dual inputs and outputs.
