ribbon driver

‘The realistic performance of the high frequencies is due to a true ribbon driver, custom-made by RAAL. Being clean and extremely detailed, it reaches up above 40 kHz. This ensures a rich and natural music picture without any colouration. 

A magical realism


The 5" midrange driver with open-back tube and uniform damping provides very smooth and airy sound, with no audible distortions. The open back tube approach allows you to listen also to the midrange driver back wave to get the feeling of magical realism. It also brings an incredible micro-detail, wide sound stage, and unbelievable instrument separation. 

Experience the base

The optimal bass performance is ensured by 10" woofers located on the side of the floor-standers. The drivers are placed in a closed volume box with floor boundary radiation reinforcement. This design allows you not only to hear the base but feel it with your whole body.
