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 NEC (National Electric Code) safety tests for in-wall usage. AudioQuest's FLX cables are also rated for direct burial. You can run FLX cables to your outdoor speakers and bury them in the ground without a protective conduit.

The best all around wire for speakers in the home.

Hands-on research

Product Research


Overview: The FLX-DB14/2 in-wall speaker cable has two 14 guage conductors to supply 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.

I HATE wires on the floor !! I got this shielded cable for running my speaker wiring in the walls and ceiling. I used monster Cable last time but knew nothing about it having to be shielded. Once again Hogan helped me choose the right product for my needs. [ MIKE  Nov 23, 2016 ]

4 questions already asked

Yes, it certainly can. Both 14 gauge wires and protective casing are of very high quality. Great product. [ Alexey  May 30, 2017 ]
Yes [ Roger  May 29, 2017 ]
I'd contact them directly but usually that's what direct burial means. The outer protector layer is pretty tough stuff on this speaker wire. [ Jacqueta  May 29, 2017 ]
It's outside diameter measurement is 1/4 inch. [ ROBERT  May 29, 2014 ]
the outside diameter is approximately 5/16" [ JAMES  May 29, 2014 ]
5/16 of an inch. Just over a quarter of an inch. The wire by the way is fantastic. The shielding makes it great, and the wire was a breeze to navigate through any hole I put in my studs and floor joists. I would recommend this product to anyone. They wire houses with 14/3, for electricity, so for audio wire this is a great product. Depending on how much you want to spend and the amount you have to run it may seem pricey. But you're only going to do it once! You will not regret the purchase. [ THOMAS J  May 29, 2014 ]
The AudioQuest FLX-14/2 in-wall speaker wire is a high-performance design that uses high-purity 100% oxygen-free copper for clean signal transfer and minimal distortion. It also incorporates "twisted pair" construction to help shield electro-magnetic interference; and its CL3 certification means it passed safety tests administered by the Underwriters Laboratory (UL). If you would like to discuss further, feel free to contact an Advisor directly by phone (1-800-324-9695) or online chat. I hope that helps! [ Larry  Jan 18, 2017 ]  Staff
The only thing you have to pay attention to is make sure you match the colors on each terminal end. [ TRAVIS  Dec 24, 2014 ]
Towards the speaker, or the flow of electrons. Think often sounds being produced by your receiver as "cars" traveling down a road to their destination- your speakers. The strands are aligned to maximize the "traffic" flow so as to be as effective as possible. [ BIIL  Dec 24, 2014 ]
Thanks Michael B.... Happy Holidays! [ Alan  Dec 24, 2014 ]
It honestly doesn't matter, but normally the signal flow from the receiver to the speaker is the direction the arrow should be. Usually with high end cables they put that on there. The cable will work either direction as long as it's good 12 or 14 gauge. Hope that helps. [ ADAM  Dec 24, 2014 ]
Towards the speakers. The signal is traveling that way [ JONATHAN R  Dec 24, 2014 ]
It should say it on the box. The arrows should point towards the speaker. [ Tim  Dec 24, 2014 ]
Alan, the arrows point in the direction of the signal, and the signal obviously transmits from the amplifier. So the arrows point to the speaker. [ Michael  Dec 24, 2014 ]
