The cone used in the RUBICON series draws upon the heritage from the EPICON technologies, and has a light, rigid and randomly uneven structure. This lower the complexity of the central part of the motor, ensures even piston like movements, reduces the possibility of surface resonance greatly and creates an extremely low distortion within the RUBICON series. The soft low-loss rubber surround is designed and bespoke specifically for the RUBICON series, and all of the components are situated in an aluminum chassis designed for maximum airflow around the cone and magnet system.

In the RUBICON series, DALI makes use of both the soft dome tweeter working alone, and the hybrid tweeter configuration an amazing rendering of the high frequencies. The voice coil used in the RUBICON series is designed to be very light and agile in order to achieve a broader bandwidth. This lighter voice coil is placed inside a powerful ferrite magnet that keeps a tight control of its movements. The ribbon tweeter is the master of wide dispersion and combining it with the soft dome, the tweeter module starts working as low as 2.5 KHz. This extreme bandwidth combined with the ultra wide dispersion is an important part of the DALI sound philosophy.
