Excelente cables para tu sistema de alta definición, se ve que tienen una buena construcción, 100% recomendados.

This speaker wire has a short metal jacket on the end of each terminal. That jacket has the name Nakamichi AND the polarity (positive or negative). The problem is that the jacket is loose, cannot be tightened and is prone to falling off. The polarity is NOT on the wire itself, just the jacket so this can be a BIG problem. I had two fall off at the same time while wiring my speakers. This is nonsense.If the jacket just had the name, it would be no big deal. If the jacket was securely attached to the wire ends, it would be no big deal. But being loose and containing the polarity is a MAJOR fail. My recommendation is to look elsewhere for speaker cable.
