Though I’ve tried some, I have never found it necessary to use expensive XLR interconnects. They were no better than -- some worse than -- simple mic cables made with Mogami W2549 and Neutrik connectors.
The need for fancy wires would be even less for low frequencies of a subwoofer. If sound quality is the goal, I would also second Blue Jeans or Mogami cables or cables made with good Mogami mic cabling.
