Thank you for viewing. This is a 3m speaker cable made by UCINNOVATE. It has banana plugs at the ends, making it very convenient to use as you can simply plug it into your amplifier or speakers. I was using this while waiting for my original speaker cables to arrive. It has good transfer efficiency and allows you to enjoy high-quality sound. How about using it to connect to your sub-speakers? - Brand: UCINNOVATE - Cable Type: Speaker Cable - Connector Type: Gold-plated connector - Features: High-quality audio playback - Package: Comes in the original box Please note that we cannot negotiate on the price.
