The new high-end tweeters RBT-10, RBT-20 and RBT-35SR
are part of the so-called real ribbon tweeters. The audio signal flows through the entire cone which is of extra low weight and consists of an aluminium film. A built-in high-quality transformer converts the low impedance of this cone into 5-8 Ω which is non-critical for the amplifier. Ribbon tweeters impress by an extra fine and brilliant reproduction of the high frequency range. Due to continuous further development, it is already possible to use these ribbon tweeters with crossover frequencies from 2,500 Hz on, depending on the type. This makes them a top choice whenever hi-fi speakers or studio monitors of the highest quality are required. Ribbon tweeters require a crossover network for operation!

“The waterfall graph shows a perfect and amazingly fast decay above the fundamental resonance frequency without any interference. ... this tweeter is a top solution for remarkably wide bandwidth applications.”
