I need some technical assistance please regarding the crossover network of the Infinity Reference Standard 9 Kappa loudspeaker, manufactured in 1989. One unit's rear Emit tweeter isn't working. I tested the tweeter and its working fine, so the problem must be caused by a fault in the crossover network. A diagram of the crossover can be downloaded from:

The Rear Tweeter circuit of the network consists of 4 components: A Cap, an Inductor, a Resistor and then something that's only labeled as RDE050A. The symbol is that of a resistor with a circle around it. Could anyone please tell me what this component is and what it's role is? I am also curious as to why this component is not used anywhere else in the crossover network - any ideas? I'd appreciate any assistance please!
