Rainbow products symbolize our commitment to technological progress and intensive research. Revolutionary innovations and developments have always served as a driving motivation for our engineers. These factors result in making Rainbow the most sought after audio products.

The highest level of quality and precision in sound and tone reproduction is what Rainbow’s Profi Vanadium Line promises - and delivers. The Profi Vanadium Line grew out of our original Profi Line, allowing our design engineers to maintain all the features that make the Profi Line so exceptional. The enhanced Vanadium Line is part of Rainbow’s ongoing pursuit of audio perfection. The woofers, mid-range speakers, and tweeters all come in foil alloys. This systematic use of alloys in all Profi Vanadium Line components ensures homogenous sound and allows for greatly improved stability and precise reproduction. Reduction of partial oscillations enhances overall stability, resulting in an unparalleled transparent sound experience.

The Profi Vanadium line offers an open, precise reproduction of voice, instruments and fast-kick bass without loss of control of bass reproduction.
