Our take on the AudioQuest FLX-16/4 16-Gauge 4-Conductor In-Wall Speaker Cable

by Amanda P.

Four-conductor design for simpler stereo cable runs

Enjoy clean, detailed sound with this four-conductor in-wall speaker cable from AudioQuest. It features 19 precisely arranged, tightly packed strands in each conductor for excellent signal transfer and low distortion. Plus, twisted pair construction minimizes radio frequency and electromagnetic interference to keep your music noise-free.

Handy extras for easy installation

AudioQuest includes sequential footage markers on the cable jacket to simplify measuring. Directional arrows tell you which way the signal should flow through the cable for the best sound. Plus, with a 4-conductor cable, you can run just one cable from your amplifier or receiver to a pair of speakers or in-wall volume control, so you'll have just one cable to pull, secure, and identify.

Keep your home and family safe with in-wall-rated speaker wire

When you're running wire inside your walls, it's important that you use speaker cable that's approved for in-wall runs. This cable's CL3 certification means it passed safety tests administered by the Underwriters Laboratory (UL). The UL looks at heat generated from current flowing through wire, how quickly the cable will catch and spread fire when exposed to flame, and the wire's susceptibility to damage from external stresses. Also, be sure to check your local building and fire code and buy wire accordingly.

Features

Overview: The FLX-DB16/4 in-wall speaker cable has four 16 gauge conductors to supply wiring for two speakers, or bi-wiring for one speaker. Using Semi-Solid packing, the individual copper strands within the bundle don't change position, resulting in reduced distortion. The long grain structure in the low distortion, oxygen free, high-conductivity copper AudioQuest uses results in a natural sound, uncolored by the cable. The Star-Quad geometry lowers cable inductance, reducing susceptibility to external noise sources.
