NEC Article 640: Audio Interconnects and Speaker Wires

Audio interconnect cables and speaker wires fall under Article 640, and so whether they can be installed in-wall or in other specific settings will depend on that article. Under NEC 640.21(C), these are in turn governed by Article 725, "Class 1, Class 2, and Class 3 Remote-Control, Signaling, and Power-Limited Circuits."

General installation of wiring, including installation inside of walls, is governed by 725.61(E), the principal features of which, for our purposes, are:

  • (1) CL2 and CL3 are always permitted;
  • (2) CL2X ("X" is a residential suffix, signifying a lower grade than plain CL2) or CL3X may be installed in raceways;
  • (3) CL2X or CL3X, if under 1/4 inch in diameter, may be installed in a 1 or 2 family residential dwelling without a raceway; if nonconcealed, it may also be installed in multifamily dwellings.

So, if a cable isn't marked CL2 or CL3, is it suitable for in-wall installation? It may be. The NEC allows cable of a higher rating to be substituted for a lower rating, and therefore, any of the following may be used: CM, CMP, CMR, CMG, CL2R, CL3R, CL2P, CL3P, PLTC. CMX also may be used where CL2X or CL3X is required.

In a plenum, 725.61(A) governs; CL2P or CL3P are required, and CMP is a permitted substitution.

A riser presents a bit different situation, governed by 725.61(B). If you're in a single or two-family dwelling, CL2, CL3, CL2X and CL3X may be used (and, of course, any of the substitutions listed above). In a commercial building or multifamily dwelling, any of those cables are permitted if they are installed in metal raceways or located in a fireproof shaft having firestops at each floor. In a commercial or multifamily building, without a raceway or shaft, if the vertical run of the cable penetrates more than one floor, CL2R or CL3R must be used (or any of these substitutes: CMR, CMP, CL2P, or CL3P).

SPEAKER WIRES July 5, 2017
Reviewer: AJG from Altamonte Springs, FL United States  
First off I cannot say how pleased I was with the quality of the speaker wires I bought.  I am having my house built and wanted to do in-wall speakers and did quite a bit of research regarding speaker wires.  Inwall Tech has by far the best price and now that I received the wires - I can see the outstanding quality of the wires themselves .  Oh they have the distance imprinted on them - Excellent !!!!

Pearl 71 and 2 subwoofers January 5, 2017
Reviewer: SRJ from Pittsburgh , PA United States  
Install was relatively easy. Running on Denon AVR 2200 and sound great. Was a bit cautious going with the no name brand but I am very happy with the results and prompt service. Exceeded my expectations.

Ceiling Speakers July 5, 2016
Reviewer: GS from Rochester, MN United States  
I bought the InwallTech® --The Pearl 71 and the speakers sound amazing!  The quality of the speakers are equivalent to any priced at 4 times the price.  The staff at the InWallStore were very helpful and quick to respond to questions.  They were very helpful after my purchase when I needed more speaker wire.  I would buy from them again for sure.

Inwall speaker wire June 1, 2015
Reviewer: J R from California  
Very happy with product and personnel knowledge.  It's not often that you can get solid info about a product from staff and Inwall "knows their stuff."  I was able to buy the proper gauge for the length of runs.
