Choosing a speaker cable is strategic: it ensures that all the information transmitted by the source is accurately and completely transmitted to the speakers. The Classic range cables are made of 99.99% OFC copper. They are as comfortable with micro-information as they are with high power. The shape of the sleeves (round and rectangular) allows the polarity to be easily identified. The CL150 Classic is the ideal cable for small column speakers and bookshelf or surround speakers in hi-fi or home theater systems (up to 10 meters in length).
