Years of laboratory testing and listening, supported by sophisticated measurements, have led us to develop tweeters
characterized by precise choices: RS tweeters use silk domes, a lightweight material with consistent characteristics
that lends itself to various treatments to enhance its dynamic performance. The dome undergoes both internal and
external treatments to create a mini-sandwich structure, preventing deformation. The suspension is treated with a
rubber-based solution for increased stability and elasticity. The voice coil winding usest copper wire, the former
is made of aluminium. The magnetic circuit uses ferrite magnet,
Every element of the tweeter design concurs in the quest for the purest sound, the ultimate target for RS.
