Sennheiser acquired Klein + Hummel about three years ago. At that time, the company was known in the U.S. only for its reference and studio monitors. In Europe, however, the company is no stranger to the installed sound space. As Klein + Hummel president Achim Gleissner explained at the company’s press conference today, Sennheiser’s aiming to leverage K + H’s success in the European loudspeaker market and raise its profile stateside in the installed sound market.

At InfoComm 2008, Klein + Hummel is showcasing its IS 122, IS 123, and IS 153 installed loudspeakers. The IS 122 is a horn-loaded 1in. model with 12in. woofer. The IS 123, a three-way loudspeaker, has a coaxially integrated 1in./2in. driver and a 12in. woofer. The IS 153 is a three-way model with a 1in./2in. coaxial driver and a 15in. woofer. Peak SPL is 135dB.

All three models are bi-amp only or available with self-powered back-plate options. The self-powered version includes factory DSP tuning.
