Quality in-wall speaker cable on a budget

Enjoy crisp, detailed sound with this two-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.

Durable in-wall- and direct burial-rated speaker wire

When you're running wire inside your walls or underground, it's important that you use speaker cable that's approved for that purpose. This cable's CL3 certification means it passed safety tests administered by the Underwriters Laboratory (UL) 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.

Product Highlights:

  • 16-gauge, 2-conductor cable (16/2)
  • UL-rated for in-wall installation
  • rated for direct burial
  • high-purity copper for high-integrity signal transfer
  • Concentric Pack stranding ensures high conductivity and low distortion
  • twisted pair construction combats interference
  • sequential footage markers printed on jacket for accurate cable measurements during installation
  • directional arrows tell you which way the signal should flow for the best sound
  • warranty: 5 years
  • Our 60-day money-back guarantee

Product Research

Features

Overview: The FLX-DB16/2 in-wall speaker cable has two 16 gauge 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.

Written By Fred, Lincoln, RI on Sunday, June 29, 2014

Crutchfield Customer Review (What's this?)

Well constructed wire and safe for home applications. Easy to route and pulling. I'm running 2 Bowers and Wilkins in ceiling speakers off of it. Even though I over ran it's capacity by 30 feet there's great sound with no distortions or loss of power.

Pros: Flexible and easy to install. Easy to prepare for hook up.

Cons: If you're installing wire yourself it does take some work getting it off the 250' spool.

Top-Notch Speaker Wire

Written By BarnStorm, Fort Myers, FL on Wednesday, June 12, 2013

Crutchfield Customer Review (What's this?)

For most, it's probably a little difficult to get excited about speaker wire. However, the more I learned, the more impressed I was with AudioQuest. From the thoughtful labeling (1-foot markers and "signal direction") to the quality of the copper to the finished product... it was impressive. All this started with my need to run speaker cable through my HOT attic so my new SONOS Connect:AMP could power my outdoor speakers. With some advice from Crutchfield, I settled on this AudioQuest cable... and I'm glad I did. Very high quality.

Pros: quality

Cons: none

Great Speaker Wire

Wire has a very durable cover and the length is stamped on the cover in one foot increments, counting down from the total length; this was very helpful in keeping up with my remaining wire to plan the next run of wire.

Pros: Heavy Duty

Cons: None

Great Speaker Wire

Written By CRW, Hot Springs, AR on Sunday, April 21, 2013

Crutchfield Customer Review (What's this?)

As always Crutchfield delivers, wiring for in celling speakers on a new home we are building, the cover is very durable and was easy to run in the ceiling and through walls. I have no concerns that it will last for the life of my home.

Pros: Wire was marked with the footage starting with the full length and counted down as I used it, this was very helpful in planning my runs of wire.

Easy to Install

Written By Colonel Army of TN, Nashville, TN on Thursday, June 14, 2012

Crutchfield Customer Review (What's this?)

Recently installed in my daughter's house before the drywall was installed. No problems, easy to work with. Easy to pull if you can cut your holes before any drywall installation. 16Ga is smaller than I thought and one of the runs is about 25 feet. For the price diff. I should have gotten the 14 AWG. Have not attached to speakers (Def Tech in wall 6.5" CLR).

Just what I needed

This is a heavy good quality wire that is simple to use. What impressed me most was the feet left numbers on the back of the wire. This made it easy to figure what runs to make first.

Expensive

Written By GK, Hampton, NJ on Tuesday, February 08, 2011

Crutchfield Customer Review (What's this?)

I guess it works well, but similar cable could be had for half the price. Should have done
more research before jumping into buying it. I doubt it is worth the extra money.
