Four-conductor design for simpler stereo cable runs

Cross section

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.

Used 2 spools to wire up 4 sets of Polk speakers during construction of a new house. Easy to run and saves time!

Just right

Crazymike from Seattle, WA on 2/10/2016

Crutchfield Customer Review (What's this?)

The release of seasons 1 and 2 of Game of Thrones in Dolby ATMOS was the straw that broke the camel's back. Four more speakers (ceiling) meant more wire to connect them and it was difficult for me to decide what to use. Since the number of ATMOS titles is still pretty low, I could not justify the higher cost of the solid LGC conductors I wanted to use. I bought some 16AWG OFHC speaker cable for really cheap and intended to double it up for 13AWG. It arrived and was a great value but I still wanted to use the long grain Copper from AudioQuest that I have relied on for two decades. With the AudioQuest FLX-16/4, I get 13AWG conductors (pairing up wires) in a single cable, LGC Copper, and the 500ft spool at Crutchfield was the cheapest price I could find. With the increased price of metals lately, $1.04/ft is a decent price for what you get. Maybe the cheaper wire sounds the same but cutting up drywall to swap conductors is not an option so I will go with what has worked for me in the past. It will be awhile before I can enjoy the sound of dragons above my head but I have something to look forward to.

Pros: The higher purity Copper that AudioQuest has used for several decades but offered at a much lower price than Type 4. 13AWG x 2 conductors for the longer, in-wall cable lengths typical for surround sound setup.

Cons: Still relatively expensive for wires that you normally leave behind if you move but not a con if it helps sell your house.

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.
