HK AudioSI Series CM-4 Ceiling Mounted 4" Installation Loudspeaker

The SI SERIES CM-4 is a high-quality coaxial in-ceiling speaker with 4“ polypropylene woofer/midrange transducer and 0.75“ aluminum dome tweeter. Equipped with high-quality, high-performance components, integrated wave guides and the uncompromising sound quality known from SI SERIES.

Its discreet, customizable appearance with magnetically attached white or black front grille makes it the perfect addition to the SI SERIES toolbox. A specially developed and stiffened steel back can makes it absolutely resonance-free. A front-operated 100/70 V transformer with bypass option and detailed equalization via DSP ensure the highest possible sound quality.

The CM-4 plays to its strengths wherever music and speech are not to take place exclusively in the background. For example in restaurants, hotels, conference rooms, retail outlets, community and club houses as well as exhibitions and galleries. Subwoofer models such as the SI SERIES S210 V or FINEO FO S112 (F) are ideal for providing support in the low frequency range.

In addition to high-quality music and speech reinforcement the SI SERIES CM-4 also offers the option of being used as part of an ENS (electro-acoustic emergency warning system) in accordance with EN 50849. Simulation data in GLL format for EASE (4.4/5) and EASE EVAC (2) is available to support the planning of demanding projects.
