Concrete Speaker CL–02: RAUBEIN 

The full range speaker drivers in the CL-02 versions are able to reproduce the complete audible frequency spectrum. The benefits of using full range drivers are many, especially when used in small speaker systems. Without the need to transition between differing specialised drivers, they are perfect for reproducing clear vocals. In addition, the selected internal components result in balanced and linear sound, perfect for desktops as well as for the living room. Given their dimensions, the CL-02 speakers are surprisingly powerful.



A rigid speaker box that does not vibrate is ideal, concrete is a perfect material for that and in fact gives a great advantage. A speaker box should only reproduce sound given by its source and it should only be the speaker components’ membrane that vibrates.



As it is sourced from close to a single point, LAUTBRECHER speakers allow for perfect spatial depiction.



The speakers can be used for both a capturing music experience in stereo mode (two speakers) as well as for vivid sound landscapes in home theatre applications (five or more speakers). The speakers are compatible with any common audio amplifier.
