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.
The Tweeter
- Titanium dome with Neoprene surround for controlled dome motion and authentic sound reproduction
- Tweeter dome with hand-stamped anti-resonance rim
- Felt pad underneath the tweeter dome to prevent turbulence
- Vented voice coil former with flexible stainless steel lead wires
- Connected acoustic volume for low-resonance frequency and optimal linear frequency response
- Ferrofluid-free magnet system for fast and precise pulse response
- 8-holed backplate to connect tweeter to the acoustic volume
- High efficiency neodymium magnet with reversible magnet energy up to 175 degrees Celsius
The Crossover
- Vanadium Line crossovers are remarkable for their intrinsic features. Fitted with low-impedan...

The Tweeter
- Titanium dome with Neoprene surround for controlled dome motion and authentic sound reproduction
- Tweeter dome with hand-stamped anti-resonance rim
- Felt pad underneath the tweeter dome to prevent turbulence
- Vented voice coil former with flexible stainless steel lead wires
- Connected acoustic volume for low-resonance frequency and optimal linear frequency response
- Ferrofluid-free magnet system for fast and precise pulse response
- 8-holed backplate to connect tweeter to the acoustic volume
- High efficiency neodymium magnet with reversible magnet energy up to 175 degrees Celsius
The Crossover
- Vanadium Line crossovers are remarkable for their intrinsic features. Fitted with low-impedance and low-distortion foil capacitors, they provide high saturation, excellent fidelity, and faithful phase linearity throughout the treble range. The low-impedance, low-stray coils ensure minimum power loss at the crossovers. Palladium-plating ensures the best possible connections, and the variable tweeter level attenuation in combination with the HALO-system prevents excessive treble output.
The Woofer & Midrange
- Extremely stiff special plastic compound basket for resonance-free operation
- Palladium-plated screw terminals for high quality cables with large diameters
- Extremely flexible surface-refined lead wires fixed via glue-points to guarantee resonance- and break-free operation
