With the latest “Made in Germany” product of our “CASA” product range, we succeeded in transforming attributes of big floor-standing loudspeakers into a compact enclosure dimension, which can be easily integrated into your individual living environment. Inside the MR-B1, the long excursion 5” chassis is beating the pulse of your favorite music, whereas the extreme high-resolution tweeter ST 40 WS with “UltraSphere™” technology is responsible for the goosebumps factor. Together, they form the perfect symbiosis of power and precision.

    Our number one aim always is to provide you with an unforgettable sound experience. For that reason, the MR-B1 comes with a specific technology we call “X-Sphere”. Core of this technology is a partial omnidirectional radiation system with consistent increase of the directivity from low to high frequencies – or briefly speaking: Your soundstage becomes livelier, wider, and more three-dimensional, however without losing precise positioning. The result is a very wide sound stage with outstanding spatial imaging and a maximum of information, even under angle. For this reason, the so called “SweetSpot” is getting wider which makes for a perfect sound experience, even in togetherness.

    This “X-Sphere” technology is technically realized by the 5” midbass woofer at the bottom of the box, which is playing against a diffuser-cone with optimized geometry. This cone spreads the low and mid frequencies well defined in all directions. The result is a radial dispersion of the sonic waves. In addition, the ST 40 WS tweeter provides a directivity index which represents the perfect balance of spatial imaging and precise positioning.
