"Colossus Speaker Cable" is a high-end speaker cable that fully utilizes the potential of your amplifier! It keeps the sound image tight while retaining the power of the low range, which tends to blur the sound image, and reproduces the contours of the mid to high ranges clearly. Using Colossus will correct any previously unnoticed out-of-focus issues, bringing out the true potential of your amp and cabinet. Colossus delivers significant improvements in high, mid and low frequencies that you'll hear for the first time from your guitar, amplifier and cabinet. The copper wire has undergone a cryogenic treatment which changes its molecular structure at ultra-low temperatures to stabilize the cable and improve signal transmission. It is also treated with a protective film containing pure gold and silver to improve conductivity and reduce oxidation. Once you try it, you'll understand why it's called Colossus. Main specifications Ultra-pure silver eutectic solder is used for manual soldering. Highly durable outer coating OFC cryogenically treated pure copper (12AWG) Diameter 13.5mm Handmade in the USA with a protective coating containing pure gold and silver for improved conductivity and reduced oxidation
