25m Outdoor Rated Double Insulated 4 Core Speaker Cable | 16 AWG 1.5mm² ACID FREE COPPER (OFC) | 100V Installation Speaker Wire For Speakers & Amplifiers

What can it be used for? You can use a speaker cable to attach your amp to your speakers. Because this cable is double insulated, it can be used for commercial grade 100V line amplifiers and speakers as well as low impedance Hi-Fi systems. The main purpose of 4 wire speaker cable is to make installation easier, for example, if you run the cable through the wall. Having 4 cores in one cable means you can just run a single cable through the wall and have it split on each speaker. Technical Specification: 30 strands ~0.25mm diameter per core. Area per core: AWG 16 (1.5 mm² approx.) Oxygen-free copper conductors for the best quality signal Outer diameter - 7.5mm Internal insulation diameter - 2.25mm Color - Black Uses both red and black and green & white internally for polarity - Simple connectivity Overview: A speaker cable is subject to high currents and voltages (totally different from signals that cables have to do with each other) and therefore needs to become good designed to prevent that the signal is lost or distorted. Speaker cable is the last line in the chain before the sound is produced, therefore it is essential that the whole signal is transmitted intact, since you will not be able to restore it later. This speaker cable has tight winding oxygen-free copper conductors and a UV-resistant and thick outer sheath. The purpose of the better quality speaker cable is to give the signal room to breathe, so that the signal can freely pass through the cable. The outcome is deeper bass, a smoother mid-range, cleaner highlights, and a wider sound stage, giving your speakers the ability to play sound as it was meant to be heard and in some cases the difference in sound when using a good quality speaker cable is almost like buying new speakers.
